So - the solution to the problem of building a flight dynamics model.
To begin with, let's deal with the most complex module of the Soyuz vehicle - the Lander. In principle, the flight time entered, until the moment of separation it has no aerodynamic forces. Everything begins at the stage of separation, when the Household compartment and the instrument-aggregate are shot from the descent vehicle and then it begins its independent movement.
Here is a diagram of the aerodynamic forces in the motion of the SA at the balancing angle of attack and the placement of the crew.
Approximate aerodynamic characteristics of Descent Module at supersonic speeds.Influence of aerodynamic quality and angle of entry on maximum loads during descent from orbitThe nature of the influence of aerodynamic quality and the angle of entry on heat flows (specific q and integral Q)Now I will install the program and try to enter the data there.
