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

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?
For?
SpaceX’s N1 Starship went away with the folding mechanism for the grid fins and just flies with them fully extended now. If we go back to the argument that these are airbrakes and nothing else… then their argument is less and less supported as of late.
Even more - with the grid fins extended on the booster stage, the rocket becomes somewhat unstable and requires a lot of engine gimbal if the drag is so high. The drag center being in front of the center of mass should cause the missile to lose control… but it doesn’t. This is because the grid fins do not cause nearly as much drag as people assume. Who would have thought that a porous object is less draggy than a completely solid one.

I’m still in the process of researching. So far the grid wings are hard to figure out
I was just saying this because previously people claimed the Falcon solely used the grid fins for airbrakes and not for steering… which was somewhat absurd. If that was the case the new Starship would have kept the foldable fins and not left them deployed from launch until landing.
Will be nice to see what you find when you’re complete with the CFD.

This is not safe to use without a flared base.
