Characteristic Analysis of Flying Process of Dispensed Object with Deceleration Parachute

Characteristic of dispensed object withdeceleration parachute is analyzed as it flies based on dynamicmodel of the object. Its flight path, velocity and accelerator ofdispensed object are studied and try to find the factor to affectflies distance according to the compute result. It is found thatthe dynamic model is reasonable because its compute resultcoincides with the experiment result. Based on the dynamicmodel and the simulation program, both altitude of dispensingand parachute-opening and dispensing velocity can be set inadvance in order to meet the demand of experiment orapplication. An available analysis method is supplied toimprove dispensing performance of object carried by flies
