Pretty good

The rudder itself adds very little drag compared to the rocket body. The rocket has 2400N, one rudder 140N

Preliminary calculation. The green one is the study of ED on R-27ER, the red one is my research on R-77. However, I made several mistakes in the calculation. So the graph may change

İs the total drag less when compared to War Thunder R-77 drag values?

The War Thunder model’s drag is not a simple number visible in datamine, it would need to be calculated as well which is a waste of time for us. Gaijin does not use math to determine such information - rather cares only if it meets certain range and performance criteria outlined in supporting data.

So, gaijin only tries to find some of the variables in the equation, to match some charts, and if these made up numbers give similar results at certain conditions to the data they have, they don’t care if the rest is inaccurate?

that’s how the entirety of the game works if you didn’t realize that by now.

I have realized this sometime ago, it’s the reason why the Su-27 flight model is an abomination I think, from what I understand

Can we see the comparison to the R-27 again when you have time to correct it?

Ok

@BBCRF
Is this polar only for fins or for the whole missile?

This is for some kind of conventional lattice wing. Where is the difference between the calculation and the conducted experiment shown

sup boys, any good news yet?
