Very interesting.

Especially the contact time in a dogfight, just a few seconds.

thanks

[LEXX]

Mostly use vertical. Nice.

[FPSOlkor]

More surprizing was that they left dogfight by diving...

[LEXX]

I saw that too. I think MiG had better acceleration at lower speeds, so diving helps gain immediate seperation *now* no matter the final end time speed. When not near aerodynamic limited top speed, diving helps for a short time no matter the airplane, and its escaping in that short time that's core. Does that sound like Correct Thinking?

Very interesting the note about shallow dive required to gain highest speed, while steep dive brings the aircraft into dense air before top speed can be reached...if I read that right!!

[FPSOlkor]

Yep, you read it right... Another point is that sound in denser matter spreads faster, and thus it is harder to catch up...
P.S. - this may explain the difference in test results from VVS and USAF... If I remember correctly top speed of captured MiG-15 was tested by straight dive

[LEXX]

mmm interesting possibility. I'll have to look back at my stuff about this dive thing.

I was wondering what this was...but your interview with Khvalenskii Stanislav Pavlovich had the answer...

— Were your planes checked for Valezhka (An aerodynamic condition that caused a plane to roll to one side at speeds close to M 0,9. O.K.)?

Not in the regiment. But I know that in the 29th IAP in Tunshan, one young pilot had crashed.

Current interview with Minin Alexei Semenovich::

— Were there cases of valezhka?
Valezhka was a serious problem. As I already said, there was a team, which tried to reduce or completely remove some deficiencies. Some problems were solved, but valezhka remained…

— What about reversing of ailerons?
I personally never had it, I don’t even know what is this. Valezhka – that I had and not once. It will turn you in such a way that you don’t know where is your head and were are your feet.

Thanks these great fantastic stuffs.

[FPSOlkor]

Valezhka (made from Russian word Valit'sya) - a severe roll to one side at speeds close to maximum. Up untill 1952 the reason for it was not found, but once located it was rather quickly solved. The problem was in different aerodynamic qualities of the wings installed on one airplane. Result was not too important at low speed, but once speed reached M 0,9 it caused rolling. Not every aircraft suffered from this condition and it's severity and speed of occurance was also different. Eventually more strict control at the plants building airplanes helped to overcome tis problem.

Reversed aerilons is a condition when at high speed wings when aerilons are applied twist in opposite direction and thus, for example, the more you try to roll to the left, the more the plane rolls to the right.

[LEXX]

Yes, I have heard about that. Thank you. I have all of Yefim Gordon's books dealing with PVO interceptors. As I don't know Russian language, its the best I can do for now. Although there are more Russian sites coming online now that deal with this, and can be translated. SAC vs PVO is my primary aviation interest. I should learn the Russian. Man thanks for these interviews.

I used to think this, but I said it elsewhere online, and someone corrected me. In a gas, speed of sound depends solely on temperature. If it was hotter at altitude, then the speed of sound there would be higher. Apparently space near Earth is really hot (as in, the few molecules of gas that there are move very fast), and the speed of sound is very high. Which surprised me, but still it seems that's the scientific consensus.
