Power Off Landing In The Huey-

No, it doesn't "drop like a rock".
Compare this to an airplane landing at 60 m.p.h. (or more)!

AND, that's NOT a "D" model...
Any UH-1 lovers out there know how I know that? ;>)

Since I only had time in the back of B's, no I don't LOL!

Greybeard said...

The "D" and "H" model look almost identical from the outside Navy, with this very minor exception.

Not a pilot
Reminds me of oldtime autogyros.
How'd he pull the nose up?

Greybeard said...

In autorotation ya still have complete control over the tilt AND pitch angle of the rotor, Ed. To pull the nose up, (similar to the autogyro), he simply moves the cyclic aft. At the start of the autorotation he pushed the collective lever down to lessen drag, then may actually have had to increase it a little to avoid overspeeding the rotor. But at the bottom, where you hear that "shush-shush-shush-shush" sound... that's where he is increasing the angle of attack on the rotors by pulling up on the collective, thereby setting the bird softly on the ground.
Neat.

Thanks.

Wow, nicely done, pretty much textbook, eh?

That's a very well done auto, in what I've always known as an "Iroquois" I've always wondered how it'd work with those lovely big heavy blades... *sigh*

The links after that video, to a few other of autos, well, some of them broke me out in a sweat.

Another thing I've never seen before (though have heard about plenty) is ground resonance. The news here all seems to have links to a recent event in Brazil with a Squirrel.
I suppose that is what happened. I've always had the living daylights scared out of me by the prospect of it, but was told that it is not much of a risk in a Robinson.
We used to drive a fair few Hughes 300's here, but I never got near to one. Apparently it was quite a risk in them.

Our biggest risk is (would you believe) burning the machine by lighting up grass when landing in the bush.

BZ, there are a few helicopters that are so easy to autorotate, you have to work REALLY hard to screw it up...
The Huey is one of 'em.
Great old bird.

Greybeard said...

And the way to tell this bird is an "H" model is to look at the pitot tube on top of the cabin. The "D" model pitot comes straight out of the nose.

Hi GB,

As usual a bit off topic but I came across this video about ground resonance, scary stuff.

Dave I can hear you saying decel,decel,decel then skids level,skids level,skids level.

Greybeard said...

Not in the Huey, A-98.
In it you keep the nose up and touch the heels of the skids first.
Lower the nose and it will carry you a football-field length before coming to a stop!
It ain't a Robbie!
