Abstract: he calculating trajectory and analyzing motion stability of a body-parac hute system are important problems of design of a recovery jystem of a vehicle. The model of rigid body-rigid body is used instead of body-parac hute system.According to the model,the motion equations and stability criteria of a body-parac hute system are given.
