Reduces engine rpm to rotor rpm. The bearings for the output shaft take the entire weight of the helicopter. Failure of the gearbox loses drive, and so long as the pilot is quick, the rotor can be configured like an autogyro, and the hekicopter can be converted to a glider. Failure of the support bearings or any part of the suspension system of the rotor is regarded as a significant probem, unless the (small) helicopter has a ballistic 'chute system, because it is usually followed by and immediate splatdown..

+Stan Albatross +Stipan Lisica He didn't explain it fully imo. He did mention most of how it works but. A video wouldn't help you at all because what you do is basically a completely normal landing. I have been in a helicopter with an instructor and asked him to do an autorotation landing. He throttle down to idle and we just slowly glide down towards the ground. While you glide down you build up rotation momentum in the rotorblades. Just like if you hold a fan up and swing it through the air without it being powered it will start spinning. When we get close like a couple meters (1 meter = ~3 foot) above ground he would just pull the collective pitch up using the built up rotation to slow down and make a soft landing. If this was video'ed from the outside it would just look like a normal landing.

lol why are guys so harsh against him

Working in the North Sea I was supposed to be on a chopper that actually had to do this maneuver into the sea, but luckily my plane to the airport from which it departed was delayed. Everyone aboard was fine, no one was even harmed. Got to listen to the audio log from that incident, and the helicopter pilot was so calm going down, it seemed like it was just a routine landing. Amazing balls on that pilot...

My father was an officer for the VNAF during the Vietnam war. When I was a kid my favourite pastime was listening to his war stories, it is something that taught me deep respect for veterans. My favourite story was his time learning to fly the Hueys delivering soldiers to the frontlines. Once I asked him what happens when the engine dies midflight, and he responded that it is the most difficult test for a helicopter pilot. I don't remember all the details, but he went through the procedure of landing the vehicle safety and saving everyone on board. One of my favourite memories that I hadn't thought of in many years.

This was (is) reasonably accurate, I was a crew chief on a UH-1N I the Air Force and a lot of factors play into how smoothly an auto-rotation landing is accomplished, starting with how well the pilot is trained, weight on board, altitude at engine failure, forward airspeed and badly everyone on board just shit their pants.

The premise that helicopters are safer than airplanes during an engine failure is false. While it's true that helicopters can autorotate, they can only do so in a very fine window while flying above a certain altitude and going over a certain speed. Get an engine failure while hovering, flying slow or flying low and you will not be able to autorotate. Also the reaction time for initiating autorotation is very low in the best of cases. It's one thing doing autorotations while practicing engine failures (and expecting it) and completely another reacting to the unexpected event in less than ideal conditions. Statistics on crashes and successful autorotations tell a different tale than your video.

Totally agree Riccardo! The guy in the video was trying to use one piece of data to make an overall assumption about whether a helicopter or airplane is safer. The answer is much more complex than just looking at engine failures, like you were saying. Before watching this video, I was researching whether helicopters or airplanes were safer. Turns out, both are extremely safe. Apparently airplanes and helicopters are safer to use for transportation than car travel. Statistically, driving your car through a parking lot is more risky than riding in an airplane or helicopter. When looking at all the data between airplane and helicopter safeness, airplanes are considered safer.

so I'm on my first week of commercial heli pilot course, and have 4 hours of flight time already and have done (assisted) over 10 auto rotations already haha, I love them, the flare is the best part, definitely loving learning how to fly!!!!

I was a helicopter power train repairman in the army. I had a hard time understanding a high energy rotor system, one of our test pilots started an OH-58 helicopter throttled up to flight rpm let it stabilize throttled down to ground idle pulled up the collective lifted up the aircraft spun it 360 degrees and set it down with only the energy stored in the rotor.

I started hearing about him after he died

A guy that I worked with who was a Huey pilot in Vietnam said that with practice and if the machine wasn't heavily loaded you could set a Huey down on auto gyro and lift off and set back down as many as four or five times.

At one time I worked at a place where a neighboring organization had a number of helicopters. They had their pilots practice autorotation landings often. However, they would appear to "glide" in for that landing. Naturally this would be hard on the skids, so they had liners on the skids which they changed often. I am intrigued that another contributor wrote in here, likening the autogyro to a autorotation landing. Though I have been told that the blades on an autogyro were not adjustable. Anyway, my old Dad talked about these a lot, so I had an idea what the pilots were talking about when I was introduced to autorotation. Fascinating! As all of aviation is.

RIP Kobe Bryant

It`ll be nice to see actual video or animation demonstration of what we are learning. More so when its a technical subject like this one - Nice channel :)

I used to fly RC helicopters and i've done a few no power landings either from a low voltage cutoff or from the motor sliding back. I've landed hard, or tipped over, but thankfully always upright (broke a few skids tho). But i still don't get how you're supposed to land with no tail servo, mainly because i've never had to do it. Is it simply a matter of action/reaction where no motor instantly removes all torque? Come to think of it, removing the torque means the helicopter will now spin the other way along with the main rotor wouldn't it?

So plane stores kinetic energy from its speed while helicopter store kinetic energy from rotor rpm

I've known for years, ever since I was a wee little lad and got myself involved with model aeronautics, more notably 3D helos. However, I can see why people would seem to think that helicopters are incapable of landing like this. How a helicopter really works seems to elude people, and most I've talked to seem to just assume they fly kind of like airplanes that can stop on a dime and hover in place. There's much more to a helo than that. Hell, 99% of the people I've had conversations with don't even know what collective pitch is or even have a faint idea of how it works!

I already know quite a bit about autorotation and the amazingness of autogyros. Still wanted to hear you explain it.

You actually don’t have to autorotate if you lose tail rotor thrust. Turning is then done using collective, and in certain situations, the throttle, changing the different torque directions.

Ian I practice to support that image.

Students learn autorotation first, not last. I am a helicopter student and if there is ever an engine failure during training or solo flight, I will be very glad to have learned this manuver in the very beggining.

The time the pilot has to react to the engine failure, although trained, is what makes helicopters drop like a rock. I've known experienced helicopter pilots die, because they simply weren't quick enough. Dependent on the model, this time is a matter of seconds. In the air, when you get an engine failure, your immediate reaction is what's happened, concluded it's an engine failure, possibly why has the engine failed and can I restart it, and/or, act upon it. By the time that has gone through your mind, you are too late. No, it is not more likely you survive an engine failure in a helicopter than in a plane. The plane will fly without the pilot doing anything. For an example, in the very common Robinson Beta R22, you have only 1.6 seconds to react. Count it out loud and see how quick that is and how when surprised by an unexpected scenario like the engine failure this time will be hard to beat even for experienced pilots

Matt Woolford im well aware of that, but most of the time you usually have a co pilot, but engine failures are rare so long as the engine is properly maintained, i would honestly rather be in an helicopter when the engine quits than a plane, since most planes dont glide too well and some really will drop like a rock, sure most plane crashes can be survived but the issue is, finding a place to land..but due to proper maintenance you have no real need to worry about either crashing, and ive seen more people walk away uninjured from helicopter crashes even at low altitudes, though i dont keep track of the stats..

@mattwoolford

7 жыл бұрын

Austin Wright not true at all. Unless you are in an F18 where it takes 20 or so computers to keep it airborne, any commercial jet is designed to be able to fly on one engine even if the performance is reduced. For those with single engines, gliding is often very easy to achieve. Even if a plane was not capable of such a feat as flying in a single engine (which they are), or in the case of dual/quad-engine failure, the pilot would still be able to glide it well. If the pilot was not able to glide it well for whatever reason (which in itself would have to be an achievement) the plane would descend at a fast, but not severe rate of descent, gain lift from the airflow over the wings and actually ascend rather than descend before it loses lift and begins descending again and so on. There is a lot of time for a pilot to react, a pilot can react more safely because even autorotation in a helicopter puts you down 10 times harder than a normal landing where gliding a relatively normal, possibly slightly hard landing would be achieved depending on how well you handle the descent. An amateur would still be able to land it well on flat grass. Planes naturally by build want to fly whilst helicopters force their way into the sky by brute-engine-force. :)

@PlutoProtogen

i know how airplanes work while gliding, it isnt too hard but you have alot of drag unless you feather the propeller, and an airliner if it loses an engine on climb, theres a high chance it will struggle to get back to safety due to the weight, but in cruise it isnt as bad, but losing both engines they will be forced to land and there arent too many places for a tubeliner to land, a small cessna possibly, but you have to remember a small hill can be the end of the aircraft as it hits the ground it will slide, the gear are more likely to collapse in a landing and if thats the case, you better hold on..if a 4 engine airliner loses 2 engines she wont have the ability to stay up and will not always have the power to climb, if it loses any more than that it is going down for sure but on a propeller driven aircraft, just pull the rpm lever or flip the switches or press the buttons to feather the props and you will be able to glide decently, but you dont glide that well...so in a way yes you drop out of the sky, you put your nose down and even then if you make one mistake your shit outta luck because you cant gain airspeed without losing altitude

You left out a very important detail. Autorotation cannot be initiated if the helicoopter does not have proper combination of airspeed and altitude. That is, if the power fails below a certain altitude without enough forward airspeed, it will not be possible to trade speed and altitude for increased rotor speed to autorotate, and thereby cushion the landing. Helicopters are very vulnerable when in hover below minimum autorotation height. If power is lost in that situation, they will start to decend rapidly, and will not recover before striking the ground. This is why when taking off helicopter pilots try to gain forward speed as quickly as possible.

This was very enjoyable and well done.

Oh I didn't think that's what you were doing. I will say, I'm a bit jealous of Destin actually getting to ride in such a helicopter doing that. Much more fun way of explaining it. :-)

Is there anything Destin can't do? :-) Mindboggling that NASA hasn't selected him yet for the astronaut program. :-)

This is badass, but I think that when most people say that helis drop like rocks, they're probably talking about a full catastrophic engine failure. like propellers shearing off and stuff that would make autorotation impossible.

It's called auto rotation. Negative pitch keeps the rotors spinning. Adding positive pitch along with a flare close to the ground counters the decent before landing.

u need way more subs than 80K.....

What do you mean. Airplane engine failure/ crashes are way more survivable than helicopter crashes

Nope. Let me explain this quickly. Planes have to glide when crash landing. Meaning they need a long stretch of open and flat ground to land on. Helicopters are far more agile, smaller and they can still move around a lot while descending. They are able to find very small spots to land with little problem. So basically a heli can land on a small street next to your house while a plane would need a very large highway. Plane=large flat area to land and cant maneuver much. Heli= small agile and can land pretty much anywhere. Also one thing I forgot to mention... When crash landing in a plane, you are going much faster then you would be then while flying a heli. That is the main reason it is safer to be in the heli

Ethan Cole but that's why airliners have more than one engine. Plus a lot of small planes can land in 50 feet. The ability to glide gives the plane a chance to reach an airport where rescue is immediate. Also planes are way safer than helicopters. You are way more likely to survive a crash in a plane than a helicopter

Star Excelsior thing is. the helicopter does not need to reach the airport. Yes the plane may have 2 engines, but in the crash landing senario all engines could be dead.

Helicopters can glide, I have heard that some have a better glide slope than fixed wing, the point is a fixed wing must maintain forward air speed in order to touch down safely. A Cessna 150 touches down at about 60 MPH where as a helicopter could touch down at 0 MPH.

I think he means, an aeroplane total engine failure almost always results in a crash landing. A plane can only perform an unpowered landing if there is a suitiable place to land, ie if you are close to a runway. A helicopter engine failure can be easily turned into an unpowered landing as opposed to a crash. Yes plane *crashes* are more survivable than chopper crashes (which have a close to 100% pilot kill rate) but if 100 planes and 100 choppers experience total engine failure at cruising altitude, 99 of the planes but only 1 of the choppers will crash.

there is a few other things considering the Autorotation, such as adjusting the Angle Of Attack on the rotor blades, etc, but othervice nice explanation

2020 we all here because KOBE RIP

I'll just say this whole kobe thing is funny and I think the shitt they showing on the news is false.

My ass! I would much rather be in a airplane than a helicopter if the engine was to die.

They can glide far... in a straight line. It's incredibly touchy to do a landing maneuver since the slightest mistake will make you permanently lose control and you'll probably need to land at much higher speeds, which might be enough to overshoot or obliterate the plane even on an otherwise successful landing. Unlike the chopper, the plane will need to maneuver onto a landing strip.

yeah me too, unless you are very low and no place to land. This thing in helicopters only works if it isn't to high.

Anyone here a pilot? It would be nice to hear from someone who knows what they are talking about instead of people who think they know what they are talking about.

As an avionics mechanic in the US Army. I like the UH-60 because it has redundant systems to avoid this. Most noticeably from having 2 engines. Aircraft can fly with one engine. The likeliness of a double engine failure is rare. Auto-rotaion is still taught though.

Learning to fly at the moment. Helicopters will drop like a rock if RPM dips too low. In the R22 you have 1.5 seconds to dump the collective and pull aft on the cyclic before it drops. R44 is 4 seconds. The higher the weight class the safer it is.

Bro 1 million subscribers,wow just a few minutes ago. Congratulations

A short video demonstrating this would have been nice to add

A really cool example of an autorotation done right is Bristow Flight 56C, a North Sea helicopter tail rotor lightning strike and no power landing on the sea resulting in all hands surviving.

Thanks for explaining it. I have always wondered how it works.

this auto-rotation stuff seems too tricky to do during an emergency. Why doesn't an onboard computer automatically take over, perform all the math, and does all the optimal maneuvers? It is crazy to have to rely on humans.

Because lots of helicopter does not have a flight computer or capable of auto pilot like planes

What I understand from talking with a pilot, the rotors are turned by the fall when pressing down thru the air. He said most helicopters would basically do the job for you. Training is minimal.

i think there is a key component of this that you have left out either. contrary to what most people think lift for ascending and descending in a helicopter isnt controlled by throttling the engine in fact the engine throttles up to a sustained and efficient point and the pilot controls lift by controlling the angle of attack/pitch of the rotor blades themselves the greater the pitch the more lift generated this is called collective pitch. in the event of an auto-rotation landing the pilot pitches the heli forward and lowers the pitch of the blades as far as they will go so they can spin freely and faster storing energy and during the flare he increases the pitch of the rotors spending the stored energy to create a bubble of lift to land on

This sounds like it would actually look good in movies.

a year a go there was a helicopter crash at cost of norway I think, where the whole rotor assebly blew off and that helicopter did fall like a rock and killed like 6 people on board

How can an engine die when it is not alive in the first place?

as a CFII-rotorcraft helicopter, i can tell people that you spend more time with the engine off then on when doing your CFI. overall the info in the video is great.

I’m an FAA helicopter flight instructor. Cool video on the basics.

I never thought about it, but this makes sense. I think water landings should have been covered though, because that sounds like death.

Helicopters usually dont operate at higher altitudes. They are for short travel and work, at hundreds of feet, not thousands. When you have an engine failure, the ground can come up real quick. A good pilot is always scanning the for open spaces.

sounds like someones listening to music on their headphones while you were recording
