The Weirdest Helicopter Ever Built?

[@johnjephcote7636]

I saw her at Farnborough and was very impressed. The way that officialdom was not behind a larger version when Canada wanted it and the way it was cut up and data 'dispersed' reminds meof many innovative British products. Sadly, I saw a scrap lorry, by chance coming past my old school at Rickmansworth loaded with very recognisable chunks of Rotodyne.

[@fryertuck6496]

Those were the last chunks of The British Empire. 😓

[@echomande4395]

Britain seems to have largely given up on innovation after World War II, with not too many exceptions.

[@DoktorBayerischeMotorenWerke]

There is no evidence that there were any legitimate orders at Fairey for the Rotodyne, Fairey was a deeply troubled company, and it seems its marketing staff made many claims that were never true... some Fairey literature suggests there were firm orders and that they had solved the noise problems... neither of these claims is even remotely true..

[@wilfdarr]

"And we'll add afterburners!" "Afterburning turboprop? I like it!" "No, we'll put them on the rotor" "🧐"

[@joshcarter-com]

It’s not easy to build a quiet helicopter in the first place, but to build one with afterburners on the rotor tips-for use in cities!-was truly a lost cause from the start.

[@talon2pro]

One of these Rotodyne built with new smaller engines (yet more powerful and reliable), components made of composites would be feasible today. I am sure the sound decibels could be lowered within an acceptable range. The gyro copter idea seems better than the Osprey's plagued twin rotors that causes more often a dangerous Vortex ring state.

[@rogergriffin9893]

Agreed. These in a modernized version would be better than the Osprey.

[@STB-jh7od]

Using modern electronic methods to lower the decibels would probably help alot.

[@sthenzel]

There was a proposed heli design from the late 80s or early 90s with wingtip nozzles, but those only exhausted air. The system used a vertically mounted jet engine with a large precompressor to power the nozzles and the rotor basically rotated around the top of the engine. While it did not need any means against counterrotation, it had a tail nozzle for directional control. Its main advantages were the complete lack of rotor adjustments, that greatly reduced complexity and therefore construction and maintenance cost, it was said it could be build for around 10% the price of a regular heli of the same size.

[@TheNiteinjail]

Run the rotors electrically... Put super quiet engines on the wings and modernize this is a real possibility

[@martinsaunders7925]

I heard it flying as a kid. It was very,very noisy at a time when aircraft engines were very,very noisy. The combination of a 90ft power rotor,two turbines and turbo propellers was over the top.

[@Phaaschh]

Something I recall about the noise problem, was that the huge size of the main rotor; coupled with the speed of rotation meant that the rotor tips were travelling supersonically. No amount of noise reduction could overcome that problem.

[@DoktorBayerischeMotorenWerke]

And that is exactly why this concept was a failure... no one has ever solved the noise problem

[@Zbigniew_Nowak]

Oh, interesting, you see, there is little talk about this problem.

[@dafyddllewellyn6636]

The blade tip speed is given in Wikipedia as 720 feet per second. At sea level, the speed of sound is 1100 feet per second. So the rotor tips were travelling at Mach 0.65 when the aircraft had zero forward speed. At 100 mph aircraft speed, the advancing blade tip would therefore be travelling at 867 ft/sec, i.e. Mach 0.79. The rotor operated in autorotation mode at higher speeds. So no, the tips were NOT travelling supersonically (the designers were not THAT stupid) - but the exhaust from the tip jets presumably was, which would indicate that the exhaust velocity relative to the rotor blades was higher than (1100 + 720) = 1820 ft/sec. That's what caused the noise.

[@DoktorBayerischeMotorenWerke]

@@dafyddllewellyn6636 Excellent comments. Yes, not the rotor tip speed, the jet engines were Ramjet type and the exhaust nozzle gas velocity was extremely high... resulting in painfully loud engine noise.

[@antberbal21]

@@DoktorBayerischeMotorenWerke Sadly after the passage of some fifty five years you are correct with the info. The Helicopter we used was a Sikorsky S-61 which was the current helicopter used in the late 1960s as part of the service which lasted into this century and made it the longest running public service to be based on the use of helicopters..

[@echomande4395]

I would love it if gyrodynes could be made to work, they look to be able to fill several niches in aviation, mostly currently filled by helicopters, and expand others (flying busses). However, there would still have to be some serious research to make this happen. Gyrodyne, including the Rotodyne, have more in common with autogyros than helicopters. The main thing is that the rotor shaft isn't driven by the engine(s) but rather freely rotates in the breeze. What allowed the Rotodyne to take off vertically was that (if I understand it) compressed air and fuel were pumped down the rotor blades and ignited in combustion chambers at the rotor tips. This rotated the rotor without creating the torque that requires single rotor helicopters to have tail rotors, however it also created a lot of noise. There would have to be a solution to the noise problem before gyrodynes could seriously take off (pun intended). Modern autogyros do have spin-up motors for their rotors however as far as I'm aware they are for ground use only. What might work for providing power to the rotor without causing torque might be some kind of compressor or gas generator feeding compressed gas into a turbine attached to the rotor shaft. With modern batteries it might be able to build a battery powered system with power for 15 minutes, enough for takeoff, landing and some hover time.

[@rockoorbe2002]

Although definitely very impressive looking and innovative for its age, that aircraft had to be a maintenance nightmare for its engine and hydraulics crews.

[@annehersey9895]

Now that there are Helipads on top of buildings, it might be time to revisit something like this especially in the US where people still live in suburbs and work downtown. I’m hopeful the noise could be mitigated although I live near a military base and helicopters still cause conversation to stop until they are gone!

Then they could have just disengaged the main rotor from the shaft when autorotation was applicable? Unless such an engine concept was not available at the time? Any way, just a thought

[@mandolinic]

With that setup, the machine would also need a tail rotor to counter the reverse torque on the fuselage. The whole beauty of the tip jets was no tail rotor was needed.

Might be possible to reduce transit noise when in gyrocopter mode but you’re still going to need to engage the rotors to carry the weight on vertical take off and landing.
