Does anyone know the term Shaviar loop (petlya Shaviara)? Is there a better English expression?
Never heard of it and wondered if it was a manouevre specific to VVS?

Any help would be, well, helpful. And appreciated.

Thanks in advance!

She turned me into a newt, but I got better.

I think it's a kind of Immelmann. You know, Shaviar must be a Russian guy. It's the Stalin era. They wouldn't say it had been invented by a German aviator... /i/smilies/16x16_smiley-wink.gif

VVS does call an immelman an immelman, as it happens.

Maybe an external loop, then? Maybe Shaviar was the first to do so in the URSS.

Anyway, there aren't too many ways to do a loop. Inside or outside, half-loop up (Immelmann) or down (split-s)...

Or perhaps an sliding loop? No, that looks too difficult to be posible...

This is the description I have of it;

To perform a Shaviar loop, get the aircraft up to a speed of 460km/h by losing a little height. Once entering the loop it is necessary simultaneously to bank the aircraft to 45 degrees. Technique for a Shaviar loop is the same as for a normal loop, with the only difference being that during its completion the same bank angle is used as at the beginning. There is no difference between right and left Shaviar loops. Bring the aircraft out of this manoeuvre at a speed of 370-380 km/h. The loop is performed without loss of height.

This is taken from LA5FN manual on http://www.airwar.ru, translation is mine.

Maybe it's just a Russian thing as you suggest DuxCorvan.

interesting

does it say anything about rudder input to keep the plane tracking at the 45 degree bank?

sounds like he's crossing inputs (e.g., right bank and left rudder) and performing a loop with the plane pointed at 10 o'clock or 2 o'clock

it could make it hard for a pursuer to calculate the proper lead on a shot

that is interesting; nothing about rudder though.

Sounds like a regular loop, but at a 45 degree angle. (planar dynamics)

sounds like a high angle displacement roll
