Numerical Formulation of Parachute Payload Decelerator System and its Animation with Moving Background

In order to study the parachute payload performance during the steady descent phase, a twelve degree freedom rigid parachute-payload with elastic suspension model is established, and its trajectory will be displayed with animation. The parachute and payload usually cannot be observed clearly for its comparatively small scale model during animation. In this paper, the reference background is built to provide references for the moving parachute.
