Flight model & calculations?

[molnibalage]

Can anybode describe me in short how it works the code and how uses the data? How is calculated the acceleration –> speed --> distance for airplanes and missiles from coeffs + physical data?

What math. method and formula is used to avoid discretisation error in case using only linear albegra and interpolation method?

How accurate is the calculation?

I do not want to reprogram or copy anyting I’m just curious.

Compute all force and torque torseur by [F,Q]=1/2Rho(Z)CX,Y,Z,L,M,NSTASTAS + THRUST(Mach,alt,RPM) + Mg
Integrate non deformable solid dynamic differential equation by any kind of Runge-Kutta or Newton Raphson method (I do believe BMS code uses regular RK4)

Thx.
