Helicopter Ejection Seat
2016-10-28 13:39:17 · answer #2 · answered by Anonymous · 0⤊ 0⤋
Not at present, but the Prototype Bell Cheyenne helicopter (which lost out to the cobra) tested a sideways ejection seat. It actually was to extend laterally from the cockpit, and after it was outside the rotor diameter, would then fire the seat. Tested with dummies, but never installed. From what I have read it would only have worked if the aircraft was in an upright, stable (more or less) attitude, hardly what you would be in if you had to eject. the Russian method, explosives to blow the rotor off (problem, blades disintegrate, explode, shrapnel etc.) then pilots eject. kind of like flying though an exploding hand grenade, not to practical. Auto-rotation, building up kinetic energy in the blades, change the pitch, pull up and set her down. Military pilots practice this all the time.

no cobra nor apache dont have ejection seats. the only helicopter having the ejection seat is the russian kamov 50 and itsderivates. of course the ejection system of Kamov includes pyrotechnic jettison of rotor blades.
Cobras and Apaches are said to have higly tolerable seats regarding hard landings, they /pilots/ should even survive the 7meters per second vertical speed.

No Cobra and Apaches do not but the Russian Kamov does.
As for an engine failure, we helicopters pilots conduct what is called an auto-rotation. A controlled decent to the earths surface with a run-on landing or a slight bump if there is no room for a run-on.

No, there are no helicopters with ejector seats right now.
Been done though. They blew the blades first, but the pilots didn't like to have to trust the system to do that, so it was dropped.
Flying helicopters has always been a risky business, they are fragile and comparitively easy to shoot down and destroy. I know people like to think that they can autorotate and live to tell the tale, but it often doesn't work out all that well.
No parachutes, no ejector seats, just an unreasonable expectation that they might get lucky and survive the crash.

Cobra and Apache have no ejection seats.
There is only one helicopter in the world with ejection seat and it's Kamov Ka-50 "Hokum" (or Alligator). Its ejection seat is quite different from usual ejection seats like Martin-beker because it's not rocket powered. To avoid impact with blades, blades are released with explosive bolts.
Ejection in other direction(forward, backward, downward, rightward and leftward) are impossible to use because human body can not stand the same acceleration in all direction, it suffer acceleration(consider opposite to ejection direction) sideward, upward(in downward ejection) and forward(in backward ejection), and ejection foreward and downward can "fire" the pilot to crush against obstacles and terrain.

How come they just don't have a Wedge block throw it's self into the mechanism stopping the blades in a X pattern. Then simply ejecting like a normal ejection seat....
Stupid engineers.

No they are designed to Auto Gyro down, and sort of do a hard landing.
The Russians had a helicopter with ejection seats, but the blades would jetison when you pulled the lever. I'm not sure if it was production or prototype.
More importantly why are the Russian 20 years ahead of us in the hottness of the tennis players? What is Bush going to do about this? I'm 33 and remember when there players had the mustaches, and not ours!!!

No.
But not for the reason you think. Ejection seats can be made to shoot DOWN also. Like some of the seats in a B-52.

No. ALL helicopters have no ejection seats, be it ejecting upwards/downwards/sideways.
Why not upwards? Make a guess.
Why not downwards or sidewards? You'd probably eject during emergencies, which is probably when the aircraft is unstable. The problem is, when a helicopter is unstable (ie. stabiliser malfunction), the direction it is heading is quite unpredictable. So escape is almost impossible.
Hope this helps, Peace.
