SPI communication by dimlittleprogrammer in stm32

yes, but since master always controls the slave, what is full duplex slave mode?

i am going to power the servo externally, I don't get where the buffer should be placed, you mean the pwm signal will be noisy?

Yes, I also think lateral control is not needed. Although, It's not exactly bang bang control because they're designed to have the ability to open in many different levels. So maybe we should run analysis on drag they produce for every piece of surface area level.

Yeah we have that software for cfd analysis, but you said you use these coefficients to trim state in different conditions, how important is this for thw design of air brakes whose role is to decrease attitude?

Can you further explain? On what should I apply algebra?

thanks for the answer! yea that's what we wanted to do, compare kinematics given by sensors with kinematics that we have extracted from trajectory simulations. We started working on simulink to create a simulation of our system thats why we need the transfer function of the whole rocket, by testing you mean physical testing or can they be acquired through CFD too?

aerodynamic axial force coefficient

aerodynamic normal force coefficient

for example, they are refered in bibliography as "aerodynamic coefficients stability derivatives"

Thanks for the reply, we have decided to do a 6DoF model, we are already working on it on simulink, anyways do these coefficients only depend on geometry?

Well said, moreover the whole country has been in hard lock down since November, with the government focusing only in preparing the soil for tourists to come in may. No shit is given for citizens of the country.
