Ejection seat switches

[ThunderChief]

There are three seperate switches to arm the ejection seat. What would happen if you activate only one or two of them? Ejection without cutting of the rotorblades? :unsure:

[Buren]

You would have a new haircut.

[Yellonet]

Another question, will the ejection handle be "clickable"? I wouldn't want to be on a long mission, 1 hour in and then by mistake click (pull) the handle :)

[Buren]

Shouldn't it activate only when you pull it for at least 1 second, so you couldn't get out of the aircraft sooner than intended? :)

[GGTharos]

Probably the ejection system won't fire. In other words, you'll be pulling on the handles and going 'wtfwhyaminotejecting' :D

 

Anyway, I find that in most cases the ejection system is useless.

How come?

[GGTharos]

You're typically too low/rolled over when you eject, and you end up rocketing yourself into something denser than air.

I would guess for at least two different reasons:

Well unless you don't HAVE rotor blades you can usually still always land a helicopter due to auto-rotation.

 

The other reason would be you just simply blew up... :D which would definitely render ejection useless! :thumbup:

 

Edit: LoL Ejecting into a house isn't a good idea either Tharos! :)

Still better then cutting off rotor blades and then no ejection...

I think the russian ejection seats have the ability to straighten in the correct position if you ejects inverted or sideways. And are zero/zero about speed and height. But only a think, i am not sure.

I've found it quite useful, especially until I master auto-rotation landing!

I believe all modern ejection seat can do that, but, I do not know if the K-37-800 can do that. I do not know if it has a pitch correcting rocket like other ejection seats do. The ACES 2 uses a vernier rocket for pitch stabilization AFAIK.

This is correct. You can remember how in 1988 Pugachev shot himself right into the ground from inverted MiG-29 at 100m during French airshow. He stay unharmed.

Theres still a minimum height for inverted bailouts, even if the seat is able to do it.

I couldn't find any pictures of that crash (I remember it was impressive).

 

But I did find these (the pilots survived, although a lot of other people didn't):

Those booms on the K-36 do wonders at higher speeds in correcting its trajectory, killing any roll/yaw and inducing a bearable oscillation in pitch (comes down to 2 Hz, do not violent at all). Guess the boom drogues also help in zero/zero ejections to corrent an offset center of gravity (like the vernier rocket beneath the ACESII). The K-36 3.5 has an option for roll correcting rockets, but I don't think anyone bought them. Besides that the new K-36 has a digital sequencer with more than 100 modes, so it will not fire the rocket if you eject inverted at low altitudes and will deploy the chute asap.

The only K-36 model that has a rocket powered pitch aid is th K-36V on the Yak-36M/38 and has 3 modes: front, center and aft, depending on the attitude of the Yak in hover during ejection.

 

Don't know much about the K-37-800, all I know is the rocket at the back has two thrust modes, a low thrust until the lanyard is stretched and full power to pull Mr pilot out along with his chute and emergency kit. I remember a figure of 90 m being quoted for inverted egress, but that's without sinkrates ;)

What crash is this ?

What crash is this ?

First it is catastrophe in Lviv 07.08.2001.

Second it is ejection of Anatoly Kvochur in Le Bourge 1989.

Thanks

 

Did Kvochur survive in the second crash ? He didn't look like he'd slow down enough. Plus he landed in the ball of fire. Can't be good.

Kvochur not only survived in that case. He had flown from Le Bourge on other aircraft and even made rolling for public at once after take off.

He is living now. Unique man. He is 56 years old and he is flying yet.

Heh...saying he's still alive is an understatement! If you ever see a photo of an Su-27 variant flying about a meter above the runway, there's a good chance its Kvochur! :joystick:
