The model of the parachute-cabin system was built with the riser being of rigidity or elasticity,which was applied for simulating the system of Soyuz.

Concerning that the characteristics change of moving parachute-mass system exerts an influence on the heavy items air-dropa,model of the heavy cargo air-drop system was established,the parachutes’ movement characteristics were analyzed,and the efficiency formula of the parachute-mass system was given.

This paper discusses the position and gesture of the recovery motion for a small UAV,analyzes the dynamic relation between the aircraft and the parachute,and establishes a mathematical model of the aircraft-parachute system during the parachute landing program.

In order to find a suitable analysis method for the aerodynamic properties of parachute-bomb system,the external flow field of the terminal guidance submunition decelerated by the parachute system is simulated in this paper.

For the air-separation process of air-launch vehicle from the carrier aircraft,this paper gives out the unified model that is the rigid body-mass point model of the body-parachute system.

This paper built up a kinematic mathematical model for a man parachute system The man parachute system was analyzed and calculated Security measures duing ejecting rescue on high altitude plateau areas were pointed ou
