In the late 1950’s, intercity air travel was on the rise. But while a trip from New York to Boston by airplane might only take about an hour, you’d still need to get to and from the airport. And in many congested cities, that was already taking longer than the flight itself. As a solution, helicopter airlines had begun to crop up in major cities, letting passengers skip over traffic to connect airports with their city centers. But helicopters were ultimately too inefficient to become a viable form of mass transport. The Rotodyne was going to change all that. Taking off from downtown rooftops and heliports, but flying faster, further, and more economically than any helicopter, the Rotodyne would be the quickest way to move from one city centre to the next.
The Rotodyne might have looked like part helicopter, part plane, but it was actually neither. Where a helicopter uses engine power to spin a rotor blade to force air down and create lift, on a Rotodyne the large rotor wasn’t directly driven by a motor. Instead it used a freely-spinning rotor called an autogyro. As air passed naturally through the rotor blades during flight, it caused the rotor spin around like a pinwheel to create lift. The Rotodyne still had wings and a pair of turboprops much like an airplane. But in forward flight, the unpowered spinning rotor lifted more than half the aircraft’s weight. To take off and land vertically and hover, tip jets at the end of each rotor blade would be used to spin up the Rotodyne’s rotor. Once in forward flight, the tip jets were shut off and the rotor would once again spin freely.
When the first Rotodyne prototype took to the skies, it could carry 40 passengers over 700km and reach speeds of over 300km/h, all while being able to land and take off on a space not much larger than the aircraft itself. And after 350 successful test flights, the Rotodyne proved to be safe and capable. But despite plans for an even larger more powerful version, a combination of noise concerns and lack of government support for research and development ultimately led to cancellation of the project.

Hi all - as some viewers are pointing out, it's a mistake to describe a 133 dB to 96 dB reduction as 15%. It's much more than that, as decibels are a logarithmic unit. Sorry for letting that error slip in and any confusion (note that 96dB is still incredibly loud).
Can you make a video about the international space station and the Mir space station
17db reduction is almost 8 times less noise! So a reduction of about 85%.
Well it reduced the noise level by 15%. The whole reason we use dB is to use perceptually linear scales. (EDIT: sound pressure level in dB is not perceptually linear. Sone is. F*ed that up) What you wanted to express is that the -perceived- noise level was reduced by 15% and that is in fact the case. Converting to linear levels, we get a far greater reduction but who cares when we don't perceive the difference as such?
I was just going to point that out.....
*113dB, not 133 while i am being nitpicky once again. :P Still wish you had that awesome Energia-Buran thumbnail picture in high res. :( (asked you a while back about it on twitter, but largest available one was still quite small)
"...and it all went to s$%t"
That took me completely off guard.

Why does the British government need to destroy all useful engineering documents of cancelled projects damnit!
That's the one part I really don't get. There wouldn't be any hassle in just releasing the docs to the public, and they could have even sold them to some other company in the US or something but they decided to just toss them?
More likely somebody have hidden agenda
More or less the same story of the Avro Canada CF-105 Arrow fighter jet.
Random Roughneck Russias eastern sides could use this, Runways are not so common there
The US also
I feel like out of all the failed projects this one is the only one im like damn thatd be cool as hell and i genuinly think it would work
Don't forget Ekranoplans. Utilizing ground effect is far more efficient than any airplane. Best part is that it gets even more efficient and reliable the bigger the craft gets
@@FlyLeah as someone who currently works as an aircraft mechanic, the maintenance with that many engines and salt water that close to the ground makes those things a tactical nightmare, not only that but like the video says, controlling the ground effect makes them super difficult, maybe on a smaller scale they might work but as large military purposes I don't think it's feasible
@@toinfinityandbeyond2082 About the stability issues I've heard its the opposite. Supposedly, the larger the Ekranoplan is the higher and more stable it flew.
The problem is the trans sonic barrier at the tips of all rotary wing aircraft. There is no way around it. This is why the only non jet powered high speed VTOL aircraft are things like the Osprey.
And that is what we need more Gen Z’ers giving us their opinion
I remember, when I was a boy, the sound of the Rotodyne. There was nothing like it. When you saw it flying over you felt like you were seeing the future. And perhaps it could have been, but it was too much ahead of its time.

It should be illegal to destroy research. Maybe shoehorn it into protections on financial records?
Agreed
People have destroyed 3D development because they make no money off ads when people feel disoriented and focus on the 3D more than the ads that make them money.
Absolutely! Engineers can get what they need from them and make something better!
Fear of this rather useful technology falling into Soviet hands, I'd imagine it could make a good troop transport/lander if further developed (where noise no longer matters). So destroying something may be shortsighted given the work and lack of any ROI you'll get, given the risk of the reds though, they must have just thought this way was better.
@@karlosbricks2413/videos Destroy prototypes and manufacturing tooling sure, but keep the paperwork and data squirreled away somewhere safe.
This seems like a technology that should be revisited.
That’s true. But when governments and such are stable.
Totally. If this was developed in the 1960s then think about how better it could be today
It will soon be superceded by electric drones.
@@Spinattitude what kinds of drones
Would be perfect for military use
TIP JETS? That is insane technology!
E
But won’t be it to be too heavy for it and disturbing the lifting force?
No, it's not. In the 1950's the Nederlandse Helikopter Industrie built a small helicopter that way. Not sure if if there's footage on YT, but has an entry in Wikipedia
Assuming a system that works, tip thrusters are an excellent way to power helicopter rotors. There's no torque. Thats why the Rotodyne didn't need a tail rotor.
The tiny Fairey Ultralight helicopter used a tip jet system back in the 50s. Its abandonment, once again, had more to do with politics than engineering.
This joke?
It almost physically hurts to see this beautiful thing to to waste. Couldn't they just resurrect the project and use today's advancements and technologies to fix the 60 year old issues?
No. In general, old technologies need to be re-engineered. I would imagine the safety standards would be different, as well as manufacturing methods. Analogy: you want to make an arrow, and have the best stone age arrow as an example; since you have no skill in cleaving obsidian, your stone arrow head will never be as good, but you can make a better steel head and make it faster with the available tools.
@@Coillcara Agreed, but the basic design is still viable and the concept is a good 👍 one. This would be a valuable aircraft for short flights. Your analogy with arrows is a good one, because the improvements and changes needed were not insurmountable.
@@Coillcara as much as i apreciate the look of the original machine, the point of the argument is to look back to this "concept" and translate it on modern design. Today we have new materials and solution to make this idea to work. Of course it will not have the same form. But the concept is still interesting
Keep in mind, this thing was being compared against helicopters, not fixed wing aircraft. There's no reason to suppose this design would be relevant. And I'm looking at a machine with too many conspicuous points of failure to go trusting it with human lives.
@@Coillcara How much different do you think the design would be, really? It's semantics to get into an argument about the incredible specificities between manufacturing of the 60s and today. Most of the groundwork is still the same.

I sometimes wonder how big of a role does "Corporate Sabotage" play in the failures of these amazing technologies.
For example, a technology like this would've significantly hurt the "Airport Taxi" industry.
There are to many examples of sabotaged technologies to count. The man who invented the diesel engine was murdered and all his designs are "missing". He had designs for all kinds of new engines that ran on different fuels. Big oil didnt like this. Also Nikola teslas research and designs were all stolen after his death. The list goes on and on. Windows and google are constantly buying up patents and small startups to either use or shelf so there is no competition.
For more information on corporate sabotage and the British government try looking up Dr Beeching and his plans to "streamline" the British railway network whilst being actively employed by a massive asphalt company that wanted the government to shift towards road transport.
It's not that far fetched tbh. Tullamarine Airport (Melbourne International) in Melbourne Australia still doesn't have a rail link from the airport to the city centre. The reason? Taxi cab lobbying.
Not just taxis perhaps. Can't see airports supporting the idea of all their short and medium haul flights being handed over to mini inner city airports. All those passengers they would loose that are no longer paying for taxis, carparks or buying over priced food, drink and all the other tat they sell in airports to a captive audience? The financial stakeholders of airports don't care if if people spend hours travelling to airports by car, train or bus with all the additional pollution/congestion that goes with it. Not only that, from an air traffic control perspective, the creation of multiple new airports and the added complexity it would bring to airspace management is something that would take a lot to sort out and probably drive up operating costs.
@@ray.shoesmith same with Las Vegas airport, the idea was to make the Monorail go to the airport but taxi companies lobbied hard and the Monorail stops randomly a few blocks from the airport serving no one in that area
When I was a kid, I put together a plastic model kit of a Fairey Rotodyne, with a detailed interior including seats, passengers, even luggage racks. I really thought it was the wave of the future. Technologically, it could have been, given a sufficient commitment.
If you still have it save that thing in a strong case. We got to save what little is left!
See Greg's Model s. Channel he makes the kit 🥰
6:54 Small correction - since sound is on a logarithmic scale, the reduction in noise wasn't by 15%, *but rather by 86%*
@DT Undercover The loudness of a helicopter is about 85.5dB from 600 feet away - so if the rotodyne was to be no louder than a helicopter, it'd have to reduce its noise by 96% from the original (or 70% from the already revised version).
@DT UndercoverYeah, something like 99.7%
@@MagicznaPanda SPL (sound pressure level; typically measured in dB) decreases with distance, like any other wave. Specifying a dB level without specifying the distance from the source is meaningless. Usually when they say "90 dB", they mean "90 dB @ 1 meter". Your 85.5 dB @ 600 ft would be hella loud @ 1 m.
How did you get the 86% exactly? It should be more like 98%
even though the sound intensity has reduced by 86%, we’ll still perceive the loudness as 15% less

Oof
Boo! Ewwgh! Bad!
Noise concerns? In American 🇺🇸 cities? Oh, come now.
"but it did!"
- someone that missed the memo
But it did
I remember the Rotodyne flying over our house! The Rotodyne was based at a small airfield called White Waltham just outside Maidenhead and as a child we lived on the direct line between White Waltham and Farnborough which was the base of the British Aircraft Establishment. On several occasions we heard the distinct sound of the Rotodyne flying over and dashed outside to watch it go over. Yes, it was noisy, but so were most aircraft at that time, especially the big jets like the Boeing 707. The difference was the big jets landed at airports outside the city centres so did not fly low over the houses, except of course the ones on the flight path into the airports. People these days forget how noisy those old aircraft were!
A few years ago I heard a racket and went outside to see what it was and was treated to the sight of a Dreamliner on its way to the Farnborough Airshow escorted by a Spitfire and a Hurricane. I could barely hear the Dreamliner - the racket was all being made by the Merlins. A beautiful racket though!

I feel like this would be the perfect model for flying cars as it removes the need for a runway
I feel like this concept should be revisited to replace medical helicopters. You could deliver patients faster while burning less fuel. A lot of development has gone into miniature, quiet and efficient jet engines that could go on the blades. The larger cab size could also allow for more than one patient to travel at a time with ambulance like medical equipment and staff there for them.
Medical helicopters are a whole nother shitshow. Back when they deregulated air travel, it was generally good for the public but it left a loophole where air ambulances can charge whatever they choose. The companies behind the air ambulances realized no one really has a choice to take one or not, that’s usually up to a doctor and the patient might be unconscious so they started charging 5-10 times more than they needed too. And especially since doctors like the err on the side of caution with lives a lot of rides are both unnecessary and hyper expensive. So just to be clear the medical helicopters are not the expensive by any necessity, just price gouging lol

This is so great to see. I’m the grand son of Geoffrey Hall who was chairman of Fairey. I never met him but to see the work he and the team of engineers in the company was trying to create is so humbling. One point that was not mentioned was that the British government had also compulsory purchased Fairey airfields which just so happened to be Heathrow, so a vertical take off aircraft didn’t suit the governments new airfields strategy? If anyone know more about this I would love to know. Charlie.
Are you familiar with Jaunt Air Mobility and Skyworks? They’re two companies working very seriously on technology that’s partially descendant from the Rotodyne, if i understand it correctly. The goal is to develop vehicles for urban air mobility, very much like the rotodyne concept. Really cool stuff.
I relish reading comments such as yours. In less than 24 hours, a blood relative of the man happened to watch this particular video and left a comment. What sort of peculiar alignment of interest and circumstance brings that about? The answer, of course, is at once obvious and yet unfathomable. I did not know this craft existed until now.

For places like small islands or isolated cities (like those Spanish cities on the Morroccan coast that actually still have helicopter airlines), this sort of thing could be a really amazing addition to their transportation sector.
I'm not so sure that Spain operates helicopter services between it's North African enclaves and the mainland. Most of these connections are provided by sea ferry services and air services using efficient turboprop aircraft such as the ATR 72.

Ryan M. Yes, at cruise. But gyrocopters are not able to take off vertically. Imagine a gyrocopter in this size with a rotor that is not powered by something. Technically interesting but I don't think that it will make any sense. 🤔🙂
No, the video is completely wrong about that. The rotor was powered but by very noisy rotor-tip jets.
Vaughn Davis Wrong. The video has it absolutely correct and it’s easy to read other sources as well. It’s described as a compound gyroplane, where the rotor is not powered during cruise, but the tip jets are run during hover and the transitions in and out of hover.
Parand ? Why imagine that? This isn’t a giant unpowered gyrocopter, it’s a compound gyrocopter.

@@ptonpc But why though?
@@Admiral_Jezza Because they are fools.

A-10 tooling is gone, Boeing is actually having to rebuild wings instead of building new and it costs way more.
Government bureaucrats.
Seems like a good application for an electric prop engine. The main rotor could also be powered to eliminate the tip jets.
@Drew Peacock probably, could be mounted on a clutch I guess
@Drew Peacock main rotor of all helicopters function as an autogyro (to some degree) if power is lost.
@Drew Peacock Yes, though it's not trivial all single-engine helicopters must be capable of autorotation to be certified.
The US Army has an award (the "broken wing") for successful autorotation under emergency conditions (usually engine failure).
@Drew Peacock you mean every helicopter ever?
Well it still has to counter the torque when the main rotor is being spun, and that's why helicopters have tail rotors or counter-rotating second rotors. The tip jets avoid this problem because the tips themselves propel the rotor, and the gas that's shot out creates reactive force.
My grandfather was a part of the production of this aircraft, and despite it not being adopted, he always spoke fondly of it. It was clear he was proud of his and his teams work, as am I.

One of the coolest aircraft that never went into service.
Canada in the late 1950s had the greatest plane that never was: the Avro Arrow with a top speed of 2,104 km/h which made it the fastest plane in the world and was scraped by Prime Minister Defeinbaker in 1959. Go figure why things are done.
You never saw it fly. I saw it at Farnborough and it was deafeningly loud. There's no way it would have ever have operated commercially.
@@johnevans388 modern jet engines are 100-110 decibels, which are slightly louder than the rotodyne proposed production model (96 decibels). modern jet engines that just happen to be attached to commercial planes that commuters use every single day... :)

Jay Jones Modern jet engines aren’t run at ear level in the middle of cities. The only reason for this to exist was to land in the middle of cities on rooftops. There’s a reason airports aren’t in the middle of office buildings.
An old coworker of mine worked on this project as a young man. He told me some of the technical issues. He liked to say that like Concorde it was ahead of the technology of the day. Even without the ear splitting noise he told me about thermal issues regarding the rotor blades and the complications of combustors in the rotor tips was just beyond what they could reliably build.
That man must write everything he remembers. We must save the data that remains.
Yeah that’s the issue with destroying all the research we don’t have any records of all the problems this plane had. It’s possible they destroyed it cuz they were worried it would made them look bad or something. Would be cool to come back see if it’s viable now
My father worked on the Fairy rotodyne at Heaton Chapel in Stockport Cheshire. We a had photo of all the workers in front of the first plane .

A "flying machine" that would be more economical and faster, got canceled because of "lack of funding". 🤔 I'm pretty sure the oil industry had a lot to do with it as well.

This is one of the most heartbreaking and sad failed projects this channel has covered so far. A genuine bummer.
The loss of this aircraft really feels like industrial sabotage.
Лэнгтон Матраверс. Hey now. More and more of us everyday are getting tired of the corruption.
I agree, it has the same air as The Tucker car story.
More like government shortsightedness and total lack of vision.
Alessandro Arcuri But it would still outperform today. just like the airship is still the cheaper way to distribute mass freight.
@Лэнгтон Матраверс. more like the pesky British aviation industry that couldn’t stay afloat without consolidation you dumb russkie.
A friend who worked at Fairey back in the late 50's said that
the prototype was deafeningly
loud when the tip jets were used
for take off and landing under load. The Napier gas turbines
and propeller tips combined to
make it almost impossible to
tolerate!
That "all went to shit" caught me by surprise
Damn, all this effort to avoid a high speed railway
High speed passenger rail is more expensive.

Mustard: Most revolutionary helicopter...
Rotodyne: Aight imma head out
youre right it's more an autogire/plane
@@Alexandre-ul7oy *autogyro
It's a gyrocopter
I had a kind of "Boys Book of Aircraft" when I was a kid. The Rotordyne was in it. With much hype as the newest and best thing around. It was going to revolutionise short haul travel. City centre to city centre.
you deserve at least 10 times as much subs, great animations, and interesting stories.
next video is gonna be: "the soviet rotodyne you didnt know about"
The Aeroflot livery threw me off.
They had probably had these in Ancient India. The west is so full of itself, thinking it has invented everything, and that history is only 2000 years old.
@@chocomanger6873 lol why you think so? first European country is over 8000 years old, Europe discovered metals and invented forging, West invented wine over 8000 years ago so how the heck it has 2000 year history can you explain?

Angelaine Jarrett that's a joke right?
@@darthsalmon3614 no. I just realized it's the name of the channel. Sorry I've been stuck in the house watching KRplus videos for 2 weeks after an accident. I like I'm losing my mind.
@@angelainejarrett1115 you good?
What about CUM word??
I remember the Rotodyne from my youth when it used to fly over my house on test flights from the airfield at White Waltham in Berkshire, where Fairey had a factory. The engine test bed was right next to the railway line that I used to travel on to school in Maidenhead and you could hear the noise of an engine test from inside the carriage! I still have an original Fairey Aviation publicity brochure about the Rotodyne and made at least two of the Airfix kits of it but sadly I no longer have them!
I feel like the fundamental design of this aircraft is something an imaginative middle-schooler would come up with. A helicopter and an airplane at the same time, and rather than powered by a motor, the helicopter rotors are powered by jets on the tips? C'mon, that's classic middle-school cool. I love it.
*_Alternative Title_* :
_Why The Vertical Takeoff Airliner Never Took off_
It's not VTOL. It's just a big autogyro. It can do short takeoff and vertical landing. Autogyros had jumping takeoff systems when rotor was prespinned to 150% of its usual RPM then angle of rotorblades was changing to high angle and autogyro was making a jump. After jump was done main engine was turned on and craft started to do normal flight.
@@orinpolansky386 smart boi but this was a pun
@@orinpolansky386 This thing literally has jet engines on the tips of the rotor blades to spin up the rotor and vertically take off. It is not a simple autogyro.
@@yeg4k165 thank u
@@orinpolansky386 I mean the creator literally has Vertical takeoff in the title sooo
I literally went on Mustard earlier to check if you had any new videos. So glad your back!
Someone needs to develop a newer version of this machine. From what I saw of that peaceful glide to the ground, it looks pretty safe to fly in.
By far one of my favourite vids by you
To be honest, I would love to fly on that thing. It looked really interesting and actually futuristic.
Maybe one with electric engines would solve the noise issue
@@DsantosGE4PA how would you power the tip jet with electric motor?
This higher quality than most tv documentaries
How this machine was not grabbed by the military is beyond me......faster than a copter, larger and less complex than the OFSPREY, it was so versatile....
The OFFSprey if it wasn't explicitly engineered to be a death trap.
Dont diasgree, but it has real issues.@@ILovePancakes24
If my memory serves me right I first found this channel through this video specifically about 2 to 3 years ago, I think it was one of the best things I did that year.
KRplus: New mustard video

I think that a video about ford airplane would be cool
I dunno about that, gonna look it up now! Thanks.
Ford Airplane??? ._. ????
@@HirokaAkita I just started a 40 minute documentary on it. Sure nuff.
@@HirokaAkita ford tri-motor like on indiana jones
Ford patented brakes and tail wheels. As well as made the first concrete runway. It's fascinating stuff!
I wander how good one Rotodyne with modern technology would be when compared with current Helicopters...
See: OV22 Osprey
@@finnmurtons8727 That's not really the same thing.
@Vitor Leão that is a good question, the Osprey is similar, but not the same beast as this thing.
The v22 has two turboprop engines, similar to the rotordyne but it lacks one thing
An unpowered rotor
Rotodyne is neither a plane, nor a helicopter. It's an autogyro- completely different type of aircraft.
Makes you grateful that we have such differing visions of what might be possible.
So much of what we see from home is often a very limited, confined vista.
This thing looks like when you put bunch of random engines and fans on your car in Bad Piggies.
Love it!
'And of course it all went to sh*t" well that was lovely and unexpected
If he keeps doing the post WW2 British aircraft industry it could easily become his catchphrase... The avro Vulcan is amazing though.
6:00 didn't expect that in a mustard video 😂😂
I like how the cgi of the models on the desk do actually look like plastic models and not jusy scaled down of the full scal ones. The table looks awesome. Like the desk of an executive
I’m surprised they didn’t ditch the tip jets and add a smaller engine they could shut down after takeoff, similar to an APU used on jumbo jets
Mustard: planes
Wendover: it's treason then
There was a small sales model of this aircraft on my dad's desk when I was a kid.
I had the Airfix plastic model of it! Sadly I could never learn to use glue in moderation...
good for yiu
5:07 I like how he does the helicopter test flight wearing a suit and a top hat! 👍😁
"the rotor wasn't powered, but wait, actually it was"
Only at takeoff and landing, yeah it's stretching it to say "unpowered" but for like 90% if the flight it is.
...like a conventional helicopter...
It wasn't. The blades are being pushed, but the rotor itself wasn't connected to an engine. It was only "powered" during takeoff and landing and its kind of a stretch to call being pushed the same as being powered.
@@jacobb17 It had jet engines attached to it for crying out loud. I would say that definitely counts as being connected to an engine, or more precisely multiple engines.
@@pauldavis5665 Not engines, boosters. The rotor wasn't connected to an engine like a conventional helicopter. The rotor wasn't powered or connected to an engine, it had boosters on it that pushed it.
Someone needs to revive this. It seems like a great idea. Even if there aren't any existing blueprints or prototypes, it can't be that hard to try and piece it together while updating as necessary.
6:51 Going from 113 dB to 96 dB is not a 15% decrease in 'noise', but much more than that. Every 3 dB is roughly a 100% difference in sound energy and 23% difference in loudness.
So the decrease of 17 dB was a reduction of loudness by around 130%.
Not sure your math makes sense there. Wouldn’t reducing noise by 130% be physically impossible? If you go from 113dB to 0 that’s by definition a 100% reduction.
Great video ❤ I love the concept
this is actually one of the first (or the first) video(s) i saw in your channel.
There's no reason the US military shouldn't have picked this up, as it seems vastly superior and safer to the V-22 Osprey, and the military doesn't care so much about noise.
If they didn't then it wasnt
@@namesurname624 maybe your not aware of how many people have died in the osprey,so dont be so sure about the militaries decision making
@@namesurname624 I don't think you understand how the US military works lol. The whole thing only exists to make money for contractors and to scare people into submission, safety is a tertiary concern
NIH syndrome.
I've only seen a V-22 in flight about a dozen times, and my initial reaction has always been "A flying Osprey! Run! Take cover!"
This should be revived as many want to avoid traffic.
That's more of a flying car thing, and _that_ is waiting on the FAA to finish their next-generation air traffic control system so that autopilots can hook into it.
Seems like it would be excellent for regional commutes, going the “last mile” from hub airports to the regional one you want, etc.
Then there would be traffic just trying to get to the takeoff location in Manhattan and every other major city. Nowadays it's probably quicker to get to one of the NY airports than it would to get to the rooftop of a midtown Manhattan building. Trust me on this.
yes, like all revolutionary techno, they get squashed
They are check into personal drones there being pushed for the same reasons.
Thx for the video!
Fun fact: At Hamilton Int Airport, there's an aviation museum that has a whole load of historical planes like the Spitfire, Canadair Sabre, (none of the Jets are operational though) and even 1 of only 2 existing Lancaster bombers. However, they also have a summer camp at the museum that teaches a lot about aviation, stories of the historical planes among other things, but at the end of the camp (Either Thursday or Friday as the camp is run for 5 days) they let you ride on a DC-3. I remember getting to ride on it when I went to the camp and it was a truly incredible experience to be on such a plane.
I really like Fairey's logo, so simple yet elegant.
