Similar issues with uncontrollable roll pitch due to the rotors creating competing vortex caused a lot of fatal accidents in the V-22 Osprey as well. The problem has mostly been overcome with fly by wire and computerized autopilot input. But when flying a literal brick that requires perfect balance between rotors, it's not exactly reassuring to think that you're one defective circuit away from crashing.
WRONG X 100!! Vortex ring state can occur with any helicopter. The sole solution is for the pilot to ensure that he does not end up in such aerodynamic condition. en.wikipedia.org/wiki/Vortex_ring_state
That's why you build in multiple redundancies and have regular maintenance and spare parts. If something is critical, then having one is having none, two is one and if you want it to work near flawless, you put in at least three. That's why these things get expensive.

Great video! I found another interesting and crazy Soviet helicopter design- the Mil mi- 32. It is actually triangular in shape. It would be cool to see a video on that. Keep up the great work!
The SH-34 (HH-34) Choctaw landing US troops in Vietnam during the Vietnam War was an interesting touch in a video about a Soviet Era vertiplane. The Ka-22 and Ka-35 resemble the Focke Achgelis helicopter known as "Hitler's Dragon".

Interesting to compare this with the V-22 Osprey tilt-rotor, the only helicopter-airplane hybrid (at least so far) to be mass produced or enter regular service, really to count as a successful aircraft rather than failure or experiment. Similar in some ways - same objectives, similar capabilities to my understanding (though I think this is a bit bigger than the V-22 - the V-22's concept could theoretically be scaled up to this size or larger though), and same basic idea of engine and rotor/prop at each wingtip. Main difference is that this has a separate propeller and rotor, while the V-22 has a single proprotor per side that serves both functions, tilting between vertical and horizontal axis. I wonder what the pros and cons of each are? This design allows propeller and rotor to each be more optimized for their role (rotor much bigger than propeller) while the V-22 is a compromise, and the complicated tilting mechanism isn't required, nor an engine specially designed to function in either orientation. I also imagine the control system design of this is simpler, the V-22 wasn't really possible (or at least not practical) until fly-by-wire came about, which didn't exist in the '60s. But the V-22's design is probably more aerodynamically efficient and possibly lighter by not having an extra rotor causing drag in horizontal flight, and the gearbox is surely much simpler by not having to have - and clutch and de-clutch - both a rotor and propeller driven by the same engine, that would reduce weight, complexity, and failure possibilities. Based on all this, I think the tilt-rotor comes out ahead, and apparently the engineers at Bell and Boeing agree.
I think though that in forward flight, the disconnected rotors essentially become autogyros, acting as extensions of the wing for extra lift and providing anti-stall safety.
It would still be useful in countries that can't support the V-22 or unable to properly maintain them. This could be seen as a cheaper alternative especially if built with today's technology.
damn can you imagine a ka-35 fully kitted with missiles on the wings, guns front, back and on the side, a spooky version, or close air support version with 4 miniguns per side and side firing rpgs, mount ball turrets at the ends of the wings and have the guns timed to the rotors so they can shoot through the props.
Any rotorcraft with powered rotor and horizontal extra propulsion is called gyrodyno. If has unpowered rotor is an autogyro. Helicopters are rotorcraft with powered main rotor that use it as propulsion without extra propellers.
Both the KA-22 and the Fairey Rotodyne only powered the lift rotor / s when taking off and landing vertically.. When cruising the rotors were un-powered and operated as an autogyro. A clever concept, that with the Rotordyne worked well, although it was never adopted commercially…Possibly too far ahead of it’s time!
I never knew THAT history of Kamov, interesting... 😎 But you should definitely do a video on the massive Mil Mi-12 (W-12 / V-12), how it came to be and why it failed. ✌️
Thanks for sharing....what an enjoyable video about two powerful Soviet made helicopter...kamov-22 & kamov- 35 strange & powerful designed helicopters 🚁
I wonder what was the intent behind attaching the KGB shield to the photo of Dmitry Yefremov. Yefremov's short biography (1920-1961) is well known in very fine detail, there is absolutely no connection to the organization.
Beautiful Kamov design (not Ka-22, though...) on Ka 31 and 35. I saw real Kamov helicopters on civil use in Romania, and some older than Ka-31 in a museum in Varna, Bulgaria. A pilot said that civilian Kamov was dull and so predictible very stable, literally boringly reliable (simple radial engines)...
On the KA-35, I don't see how a turbofan/turboshaft engine could work. With the engines powering the rotors, they'd also be producing forward thrust, so hovering would not be possible.
I seem to recall that helicopter-plane hybrids want to keep them spinning slowly rather than stopping them, as forward motion would cause excessive aerodynamic loads on the rotor, possibly more lift on one side than the other, without centrifugal force to counter it. If stopped the rotor would tilt over and hit the fuselage, or the blades would bend upward or downward, possibly breaking them. As long as it's spinning, centrifugal forces keep it reasonably level (within limits) and straight. Helicopter blades aren't really rigid, they're quite flexible (we see them sagging under their own weight when a helicopter is sitting on the ground, said own weight is tiny compared to the weight of the helicopter), could never withstand the aerodynamic forces without centrifugal force holding them out - sort of like the string of a weedwhacker. And likewise I understand that most helicopter rotors are not rigidly connected to the mast but free to tilt, to control roll and pitch the blade angles are changed side-side or fore-aft with the cyclic pitch control, which tilts the entire rotor disc (forces have to be applied 90° from the desired tilt axis due to gyroscopic effect), the helicopter fuselage basically dangling under it. Having it spinning helps keep it level, I vaguely recall a helicopter pilot explaining that more lift on one side is compensated for naturally (no pilot input required) by the rotor tilting up on the high-lift side, the blade moving down - having a higher angle of attack - as it goes over to the low-lift side, resulting in balanced lift, the blades moving up and down through the tilt compensates for the different amount of lift due to different relative airspeed. Plus the rotation axis remains vertical relative to the helicopter, centrifugal force pulls the blades perpendicular to that - thanks to this single-blade rotors or propellers are possible (and do exist though are quite rare). Thus on a helicopter-plane hybrid, the rotors wouldn't be supporting the weight of the aircraft, meaning less forces that would need to be counteracted by these effects, so it doesn't need to go full speed. But even with the rotors neutral-pitch going so fast would put forces on the rotors that would damage them if not spinning. They would go slower than usual to reduce power consumption (I think just auto-rotating by setting the blade pitch, similar to a gyrocopter, but relatively slowly so they don't produce as much drag as they would if auto-rotating at full speed), as well as to avoid tips going supersonic (or even transsonic) as forward speed increases. Advancing tip velocity = airspeed + rotor speed (in rad/sec ideally, otherwise conversion factors are needed) * rotor dia/2. This needs to be kept subsonic, so slower rotor speed allows for more airspeed without hitting this limit. I seem to recall one helicopter-plane hybrid design had the rotor tips packed with depleted uranium to maximize centrifugal force on the rotor, allowing it to spin slower without damage. I do think I've heard of other concepts that actually do stop the rotor, but they use a very different rotor design. Shorter, wider, fully rigid blades, look more like airplane wings than helicopter rotor blades. If I remember right that would stop with the rotor blades perpendicular to the fuselage and they would act as wings. I'm a bit skeptical of how well that would work though, as such short and wide-chord blades would be rather inefficient as a helicopter rotor. And there's the problem that as the rotor is slowing down or speeding up it would get too slow to act like a helicopter rotor but at moments be parallel to the fuselage, effectively meaning no wings, so transitioning between helicopter and airplane mode would be problematic. Maybe it had fixed wings as well, once the rotor is stopped it was a biplane. Or maybe it goes zero-G during the transition so lift is momentarily not needed. Or maybe the designers hadn't thought of that problem. Probably a much longer answer than you were looking for, but it's a very interesting question.
@@quillmaurer6563 All the examples shown in this video has fixed wings. I got a hunch transition to the ga horizontal flight may be simple. But as you mentioned, back to helicopter mode may be not as responsive. Hmm. Definitely i would think something more rigid blades as they also an airfoil or wings. Like if somehow can be stopped, it would be a kin to an + or x shaped wing. Which if they kept free spinning i think would interfere while at high horizontal speed. Like all the experiments here 'only' aiming at 400-500kmh ish maximum airspeed. You have explained this but, thinking from my perspective. Also an option to 'pack' the rotor when not in use but it would be sluggish to unfold and would need extreme precision design. I think? Or maybe ducted rotor design? But it has dimension limit. Then again idk how fast it will transition to helicopter. Imagining from near mach 1 to a safe airspeed for hovering. The duct will keep the rotor not interfering while at horizontal flight. But from all of my ideas, i think this is the most plausible option. Although will need multiple of those, not just twin.
@@ericstromberg9608 It seems they provide drag and unnecessary turbulence to me. During the horizontal flight. Helos do not flying horizontally (they tilted down-forward while flying to get the forward push), but those planes does. As the fixed wing would provide most the lift during the time. I could be wrong, but it is what i see.
This was contemporary with and similar in concept to the civilian Fairey Rotodyne which had a single rotor, half the power, half the lift capacity, and 60% greater range. The Rotodyne didn't have the stability problems of the Ka-22 but it did have noise problems due to its tip jet rotor propulsion which conflicted with its intended ability to fly direct to city centre airports.
Living only 5 miles from Westland Helicopters, I saw the Fairey Rotordyne fly several times. The chief engineer, Vic Rogers, was our next door neighbour. It was a great idea that worked well…it ought to be re-visited with more modern Technology.
Hate to be annoying, but a double letter designation such as "SU" and "KA" would be said "Es-Yoo" and "Kay-Ay," as in vocalizing the individual letters. Edit: We can just call the KA-22 the "Platypaircraft"
No, because it's an abbreviation and not the first/second letter of the word. Ka is short from Kamov, Su is short from Sukhoi, Tu is short from Tupolev etc. These are all the last names of the plane designers, so Ka/Su/Tu etc. are just abbreviations of their last names. On the other hand F/A-18, for example, is a double letter designation with F standing for Fighter and A for Attack so these are vocalized as individual letters. Check any Russian documentary and see how they read aircraft names :)
Never understood why you anglos do that pronouncing letter by letter instead of just pronouncing the combined syllables. SU, KA, just read it phonetically not the anglo nonsense shifted vowels.
so it is like an Osprey but without the rotors capable of pivoting up and down, despite being more simple than an Osprey the thing is still a complex machine.
The Fairey Rotodyne avoided KA and Osprey limitations decades ago by using the large rotor for taking off and landing only. It was physically separate from the props, could double as a 'parachute' in the event of main engines failure and use free spinning to generate electricity. Also it was pressurized which the Osprey cannot be. Kamov's twin large rotor system was too complicated and always linked to motive engines whereas Rotodyne's gyroplane classification achieved what the others -- old and new -- could not and even early tests showed that airliner speeds of the period were built in. It failed because the USA cancelled orders on grounds of 'noise' and bullied Canada to do the same. Noise levels from the rotor tip boosters were reduced to being below the levels of Boeing and Douglas airliners but a foolish UK government failed to support development. Russia would have advanced ALL of its aviation (inclusive of lift gyrodynes for the BAM railway project) had it used Fairey Co design personnel.
This is the main reason why the Americans and the Russians compete for when it comes to war machines. It produced mixed result like in the past up until now. Also aside from companies america and russians also are manufacturers of death. Like how the Russians and the Americans used Afghanistan as their so called adventurism. This wars were created by both nations so that they could test their readiness and of course profitability of their weapons and war machines. It also serves as advertisement for their wars. For example how helicopters were widely used in warfare. Its like how Americans manufactured the Vietnam Wars where it was the first wars that fully utilised the capability of the Americans. But despite how the Helicopter revolutionised military mobility and warfare it also goes to show how vulnerable low flying slow moving helicopter. Americans and Russians sacrificed their footsoldiers just to test this helicopter usage in Vietnam and Afghanistan wars. Both the Americans and the Russians failed in Afghanistan. For these two world powers escape the humiliation of defeat and the numerous death and destruction they created they call those who serve and died in those wars a war heroes. Heroes is the key word every now and then.

This hybrid gyroplane design should be reexamined with modern materials. Imagine the Osprey internals with use with this design.
On the KA-35, I don't see how a turbofan/turboshaft engine could work. With the engines powering the rotors, they'd also be producing forward thrust, so hovering would not be possible.

I always had this favorited in my tabs because I found it while looking at other kamovs but there was no information about it, I didn’t think it flew.
Basically the real Airwolf in terms of propulsion concept. I wonder if the rotor blades can be fixed during horizontal flight.

And there's the problem that as the rotor is slowing down or speeding up it would get too slow to act like a helicopter rotor but at moments be parallel to the fuselage, effectively meaning no wings, so transitioning between helicopter and airplane mode would be problematic. Maybe it had fixed wings as well, once the rotor is stopped it was a biplane. Or maybe it goes zero-G during the transition so lift is momentarily not needed. Or maybe the designers hadn't thought of that problem.
Probably a much longer answer than you were looking for, but it's a very interesting question.
@@quillmaurer6563 All the examples shown in this video has fixed wings. I got a hunch transition to the ga horizontal flight may be simple. But as you mentioned, back to helicopter mode may be not as responsive.
Hmm.
Definitely i would think something more rigid blades as they also an airfoil or wings. Like if somehow can be stopped, it would be a kin to an + or x shaped wing. Which if they kept free spinning i think would interfere while at high horizontal speed. Like all the experiments here 'only' aiming at 400-500kmh ish maximum airspeed. You have explained this but, thinking from my perspective.
Also an option to 'pack' the rotor when not in use but it would be sluggish to unfold and would need extreme precision design. I think?
Or maybe ducted rotor design? But it has dimension limit. Then again idk how fast it will transition to helicopter. Imagining from near mach 1 to a safe airspeed for hovering. The duct will keep the rotor not interfering while at horizontal flight. But from all of my ideas, i think this is the most plausible option. Although will need multiple of those, not just twin.
I think they need to autorotate to provide lift.
@@ericstromberg9608 It seems they provide drag and unnecessary turbulence to me. During the horizontal flight. Helos do not flying horizontally (they tilted down-forward while flying to get the forward push), but those planes does. As the fixed wing would provide most the lift during the time. I could be wrong, but it is what i see.
This was contemporary with and similar in concept to the civilian Fairey Rotodyne which had a single rotor, half the power, half the lift capacity, and 60% greater range. The Rotodyne didn't have the stability problems of the Ka-22 but it did have noise problems due to its tip jet rotor propulsion which conflicted with its intended ability to fly direct to city centre airports.
Living only 5 miles from Westland Helicopters, I saw the Fairey Rotordyne fly several times. The chief engineer, Vic Rogers, was our next door neighbour. It was a great idea that worked well…it ought to be re-visited with more modern Technology.
With the lift rotors placed laterally, weight balance on the length axis must have been tricky to manage. No mention of that?
Chinook and it's banana like predecessor seemed to do fine without too much sensitivity to lift imbalance.
I LIKE IT, SO COOL LOOKING!!👍
Yes we need that sh*t
there is a guy bringing a kamov 6 back from being parked in 92. they are about to fly it for the first time
Pesawat baling2 2 nya pendorong jet/ roket di belakangnya di pasang aja biar cepet bos
Fascinating!
Hate to be annoying, but a double letter designation such as "SU" and "KA" would be said "Es-Yoo" and "Kay-Ay," as in vocalizing the individual letters.
Edit: We can just call the KA-22 the "Platypaircraft"
No, because it's an abbreviation and not the first/second letter of the word. Ka is short from Kamov, Su is short from Sukhoi, Tu is short from Tupolev etc. These are all the last names of the plane designers, so Ka/Su/Tu etc. are just abbreviations of their last names.
On the other hand F/A-18, for example, is a double letter designation with F standing for Fighter and A for Attack so these are vocalized as individual letters.
Check any Russian documentary and see how they read aircraft names :)
Never understood why you anglos do that pronouncing letter by letter instead of just pronouncing the combined syllables.
SU, KA, just read it phonetically not the anglo nonsense shifted vowels.
@@Argentvs does Anglos include Caucasians?
you know the people who invented that language.
needed a few touches In order end its journey
How about an episode on the british Hotol ?
so it is like an Osprey but without the rotors capable of pivoting up and down, despite being more simple than an Osprey the thing is still a complex machine.
Its not complex, but fascinating. I wonder if somehow this thing manage to achieve commercial success
I have dreamt of a jet helicopter... but F35 can do the same...
Soviet vessel likes to StarTrek USS Enterprise NCC-1701. A peaceful, science vessel with cannons and torpedoes.
The Fairey Rotodyne avoided KA and Osprey limitations decades ago by using the large rotor for taking off and landing only. It was physically separate from the props, could double as a 'parachute' in the event of main engines failure and use free spinning to generate electricity. Also it was pressurized which the Osprey cannot be.
Kamov's twin large rotor system was too complicated and always linked to motive engines whereas Rotodyne's gyroplane classification achieved what the others -- old and new -- could not and even early tests showed that airliner speeds of the period were built in.
It failed because the USA cancelled orders on grounds of 'noise' and bullied Canada to do the same. Noise levels from the rotor tip boosters were reduced to being below the levels of Boeing and Douglas airliners but a foolish UK government failed to support development. Russia would have advanced ALL of its aviation (inclusive of lift gyrodynes for the BAM railway project) had it used Fairey Co design personnel.
why V22 can't be pressurised? due to the tilt mechanism?
Pressurised? So you can fly it at high altitude?
Soviet: So comrades, what if
AMAZING
Does ot bother anyone else that the model shown has rotors that are supposed to turn the same direction but they counter rotate?
starboard rotor is wrong. if it is vouter rotating.. then the blades need to be mirrored as well
Sikorsky S-97 is already in development
KA22 looks kinda like a unrefined version of V22 Osprey
Please do a video for Mi 24 series
osprey, but.. not osprey
Osprey rotodyne lovechild.
Did rotors on Ka-35 had their own engines, or they take power from the jet engines?
with distributed electric power it could work in present day pretty well...
soviet engineers when no magellanTV: bruh
soviet enginners wwhen magellanTv: ez sercet intel
The right helicopter propeller blades are reversed in relation to the rotation direction
wait is this channel riding off the mustard format? This is like watching a mustard video, down to the animations... hmm..
just thougth the same thing
Awesome! 👍🤗
Awesome indeed!
I believe the Soviets got some inspiration from the German made Focke Achgelis FA 223
As the author mentions, the inspiration came from Bratukhin B-11, which in turn was a late development of Bratukhin Omega that flew back in 1941.
This is the main reason why the Americans and the Russians compete for when it comes to war machines. It produced mixed result like in the past up until now. Also aside from companies america and russians also are manufacturers of death. Like how the Russians and the Americans used Afghanistan as their so called adventurism. This wars were created by both nations so that they could test their readiness and of course profitability of their weapons and war machines. It also serves as advertisement for their wars. For example how helicopters were widely used in warfare. Its like how Americans manufactured the Vietnam Wars where it was the first wars that fully utilised the capability of the Americans. But despite how the Helicopter revolutionised military mobility and warfare it also goes to show how vulnerable low flying slow moving helicopter. Americans and Russians sacrificed their footsoldiers just to test this helicopter usage in Vietnam and Afghanistan wars. Both the Americans and the Russians failed in Afghanistan. For these two world powers escape the humiliation of defeat and the numerous death and destruction they created they call those who serve and died in those wars a war heroes. Heroes is the key word every now and then.
So soviets had the idea for the v-22 first?
I guess the designers for the v22 got inspired by this aircraft
reminds me on the Rotodyne
Watching with auto-generated captions: "The karma car 22"
I'm getting the Rotodyne vibes.
Nice!
On another note, I can't think of any reason Australia shouldn't invest in a fleet of V-22, can you do a video to prove me wrong/right
A foundation concept for tilr rotor helicopter
Where's the gift code for free trial?
You should do the cx hls proposals of the c-5
is it the same type of aircraft as the rotodyne from Fairey Aviation?
Yes
