Ilyushin Il-28 Beagle in Pakistan Service and Ejection History

[Chogy]

But does the 33% power give accurate results, or is it just to familiarize oneself to the extremes.?

It's simply for familiarization, so you'll more easily reach for the handles if you need to.

And what effect does the wind have on somebody, the volumes of air pounding against you, and is there a risk of simply ramming against the canopy? Or into some other objects?

Consider that a human in free fall reaches no more than about 120 to 180 mph, or maybe 100 to 130 knots. At that point, he stops accelerating. Ejecting at 500 knots, the wind can produce horrible flail injuries... but the system is designed to get you clear of the hardware surrounding you.

On occasion, someone can bang their leg, or if they don't sit back straight, they can end up hunched over, which is very dangerous.

from the videos I have seen on this subject Iearnt that the time pilot is ejecting from the plane is the most dangerous part of all but the the way Jet's windscreen is seperated and actually shields the pilot from the incoming wind saves him frm sure death.

Wonder if ejection through the canopy ever became practical.

IB, the Soviets had some excellent seats, and some of them rotated the canopy on pegs so that the canopy did shield the pilot from wind blast.

There's advantages and disadvantages to this. Subsequently getting rid of the canopy is another complexity added to an already complicated sequence. But it beats the heck out of ejecting at 600 knots.

One final issue is that these parachutes are really small, and if you weigh more than 80 kilos, you are going to hit very hard. I weigh about 100 kilos, and the times we practiced with a real parachute, it hurt. The last thing you need in an evasion scenario is a bum leg or knee.

Windjammer, if the canopy doesn't separate, you are going to punch right through it. It's already happened many times, and remarkably, it's supposed to be no big deal.

Airplanes like the BAE Hawk and the F-35 have det cord in the canopy that shatters the plexiglass, and the canopy isn't even jettisoned for ejection.

Does anybody have any images of H5 or Ill 28?
