I learned to fly the Huey in 1968. I later became an instructor pilot. When performing simulated engine out autorotations in those days it was US Army policy to take the aircraft all the way to the ground, sliding it a short distance and braking the forward motion by lowering the collective slowly putting full weight on the skids. It was sometime in the late 70s/early 80s that full autorotations to the ground were suspended. Autorotations were now to be completed with a power recovery to a 3 foot hover. It was found that there were too many instances of helicopters becoming damaged doing autos to the ground than there were actual engine failures to justify doing the full maneuver.

It's unnecessary anyway, since the engine, below a certain RPM, won't be providing power to the rotors. It's probably best to maintain that connection anyway. It makes aborting the test simply a matter of throttling back up again.

People calm down it is real, the engine can still be running, the rotor has an overunning clutch which allows the rotor to maintain rotor speed with engine idle during decent. The pilot controls the rotor speed by using the decent to create both Thrust for the rotor blade (rotate faster) and Lift (Slowing the rotor) There is a balance point in which the pilot must control.

In the UH1 and most other turbine driven helicopters, the “power” section of the turboshaft is a free turbine. So there is no need for any clutches to disengage to freely rotate the rotors. Im pretty sure. The engines provide a very tiny bit of power to the system when the throttles are at idle, and that little power is so little that its basically the same as shutting down the engines.

Roll the engine to idle, lower the collective. Aircraft will start to descend. Lower the collective to keep the rotor disc spinning. Pull too much collective and the rotor's angle of attack to the wind will be too great and it will stall just like an aircraft wing. (you will drop faster than a rock at that point). Start putting in collective as you get lower to slow down and do a running landing. Was a crew chief on a UH-1H. Pilots have to practice auto rotations to stay current, though most were not done all the way to ground. That can be hard on the airframe.

For an autorotational check you lower the collective first so you DO NOT DECAY ROTOR RPM before you roll the engine back to idle. Maintain the rotor in the green all the way through the event until full stop. Then you roll the engine back up and wait for the MP or the IP to initiate the next maneuver.

The rotor blades on the Huey, UH-1, UH, for Utility Helicopter, are 48 ft long, (Tail rotor is 8ft long). The main rotor blades have a 21 inch cord, which means they are large flappers and weight is added to the ends. They have tremendous inertia. The Huey is the Only Helicopter that can be set down, power cut off, and the inertia of the rotor blades can still lift n hover the chopper, 4 to 5 ft, do a complete 180° pedal turn n sat back down, all done by the energy of the inertia (energy) in the rotor blades like a large flywheel. Newton's law applies here. A body in motion, tends to stay in motion. Long story short, if a Huey pilot cannot autorotate the Huey down, with all that inertial energy (and weight to keep them spinning) at his disposal, he's not worth a damn as a Huey pilot. Lighter weight choppers are more of a challenge to autorotate, but can still be done. ALL Helicopters must be able to autorotate to be certified by the FAA...

Just an FYI, this is called a power off autorotation. The throttle is rolled back to flight idle after the collective is lowered to its lowest. That removes collective pitch from the rotor and the helicopter descends. The rotor continues to turn because air is driving the rotor system, not the engine. In this particular video, the pilot rolled the throttle back to full open prior to getting close to the ground and terminated the autorotative approach to a hover with power. The reason the rotor system continues to turn with the collective control full down is because the pitch change links are adjusted to have a small amount of pitch when the collective control is full down, enough so the wind going through the rotor will rotate it at the same RPM as during normal operations.

You can perform the maneuver in different ways... Such as sliding it when on a runway; greasing the runway.... Or if landing on rough terrain simply stalling the rotor system with the helicopter a foot off the ground. When I was an instructor pilot at Fort Rucker we used to have a blast thinking up different ways to end the maneuver. Loads of fun. Starts out with a 9:1 descent to forward movement ratio. At about 100 feet you put in a little angle on the rotor blades which causes your descent rate to reduce; instead of dropping like a rock you begin sliding forward, then at 50 feet you begin a slow steady input (raising the collective) and increasing the angle of,the rotor blades and creating more and more lift, so you can basically touch down with no forward speed. When the 'no forward airspeed' method is used the helicopter behaves like a bear that is shedding water.....everything is shaking and shuttering as the rotor speed drops and the rotor system finally stops producing lift and you just drop to the ground, or the front end lowers to the ground much like a controlled landing....right front then left front. SO MUCH FUN.

Brandon Matthew asides of nerves and not having the chance to recover if you mess up the descent, this is, if we're talking the flight dynamics of an autorotation, it does not matter at all wether the engine is still running or on idle, if rotor spins faster than the engine it will "detach" and spin on it's own, hence the name autorotation

If by "MUCH different", you mean "almost exactly the same" then I agree with you.

If you roll the throttle back you have no engine power. So they are pretty much the same concept

Anthony Italiano When the turbines are idling, the clutch disengages and the rotor spins freely. Have you ever watched a helicopter start up. The turbine starts first, and they usually idle for a few minutes while the pilots are finalizing the preflight inspection, then they give it more throttle and engage the main rotor.

set throttle to idle will cause the engine rpm decrease immediately. as long as engine rpm is below rotor rpm. it will not drive the rotor

the engine is at low RPM it wont create lift. It's left on during practice in case they need to power out of the auto rotate by increasing the throttle. It's like being in "Neutral" in a car, engine running but it doesn't affect forward motion. In an emergency, the pilot can put it back in "Drive" per say, to get out of trouble.

I made helicopters for thirty years, and as a professional, I have to speak out and say that I can clearly hear the engine on this video. This is a fake. I'm reporting it to KZitem for having a misleading title.

Have fun reporting every fucking youtube video lol. If you were a "professional" you would know what torque is. I think what you mean to say is you sat watching a bunch of people put together helicopters for you for thirty years and got payed by the hour for it.

No torque to the blades at idle. That's why a helicopter stays on the ground when it idles

If you had bothered to actually read what the video's creator has said you will of had noticed that the engine is not creating torque: helicopter training in rotations have never involved shutting the power off completely because that would be unnecessarily dangerous.

David Taylor "It's not dangerous if you know what you're doing". Well hello there sunshine, these are trainees: they don't know what they are doing, which is exactly the reason why they're going through... You guessed it, training! If you are an untrained pilot and your instructor wants to teach you autorotations, it's a damn lot safer for them to just cut off the torque (therefore allowing the instructor to grasp back control in a bad situation) than cut off the engine. If you know what you're doing and you're in the middle of nowhere? Sure, cut it off completely if you want. But if by that bad luck you somehow fuck it up and can't regain control (since the engine is off, after all), there's only yourself to be held responsible.

Nope. This is something every heli pilot has to do to gain their license. They cut the throttle back but they leave the engine on in case of emergency. In a real situation you'd see the same thing without the noise obviously.

The title says without engine POWER. The pilot overrides the throttle which disengages the sprag clutch thus: no engine power to the rotors.

A real auto rotation shut the engine down flame it out. The training still has the engine running at idle. Not real engine out auto rotation. Even a idle turbine engine has power to the rotor.
