Zusammenfassung:This paper considers aerodynamic characteristics of a descent module and the parachute compartment hatch door (PCHD) during separation from the descent module, taking into account aerodynamic interference. The numeric simulation was done using FlowVision. Simulation on dynamic mesh yielded trajectories of the hatch door in the Earth atmosphere for different parameters and initial conditions of separation. Cases of collision between the descent module and the hatch door are identified, and the influence of gravity on the aerodynamic characteristics of the module and the hatch door are analyzed.
