Abstract—Characteristic of dispensed object with deceleration parachute is analyzed as it flies based on dynamic model of the object. Its flight path, velocity and accelerator of dispensed object are studied and try to find the factor to affect flies distance according to the compute result. It is found that the dynamic model is reasonable because its compute result coincides with the experiment result. Based on the dynamic model and the simulation program, both altitude of dispensing and parachute-opening and dispensing velocity can be set in advance in order to meet the demand of experiment or application. An available analysis method is supplied to improve dispensing performance of object carried by flies.

Index Terms—Air-drop, deceleration parachute, flies path, simulation.
