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.
