hi-speed ejections

The K-36 seat has telescoping booms that extend REARWARDS - to stabilise the
seat - in much the same way as the small drogue chute on western designs.

I though it also had a wind blast deflector the popped up *in front* of the
seat?

It does - a sort of telescoping arm between the pilots knees, with what looks like
a small mesh screen.

But looking at photos, it only seems to extend to groin/stomach height.

I'll see if I can find a photo.

I also read recently that the Martin-Baker seat on the Rafale had a device whereby
the pilot does not need to attach his ankles to the seat - it is all done
automatically.

This was supposed to be a wonder development - but the K-36 seat has had it for
years!

It has a webbing strap that goes from the outer side of the seat, next to the
right side of one ankle - then up and over the footwell and attaches to a pulley
on the seat on the left side of the ankle - same arrangement for the other ankle.

So the pilot sits down and puts his feet on the rudder pedals in the footwell - he
doesn't have to attach any ankle straps.

As soon as the seat fires, these webbing straps retract, pulling his ankles onto
the seat. There are also risers behind his knees to raise them towards his
stomach, the aforementioned windbreak, the stabilising arms etc.

All in all a very effective design - as demonstrated by the K-36 Ejection Seat
Display Teams at RAF Fairford (two) and Le Bourget (three)

The version of the K36 was also to be found on the XB70 Valkurie. I
recall reading (in Wings i think) that the only survivor of a XB70
F104 mid air crash got his hand caught in the seats clamshells; when
he finally got his arm out and ejected the shell didn't close and he
recalls seeing the XB70 and F104 debris tumbling away from him through
the gap in the clamshells.

I'm sure you're right. I saw a "Discovery Wings" programme recently
that showed the mechanics of the Russian ejection system. Wind
deflector at front, and rear booms on seat for stabilisation. I'm not
sure how this compare with the latest Martin-Baker zero-zero seats.
