ABSTRACT
Considering the characteristics of the airdrop process and the main purpose of numerical analysis, in order to reduce simulation difficulties and calculating time, the airdrop simulations are simplified as follows:
1. Choose the cargo extraction time from when the cargo platform geometric center reaching the cabin edge to the parachute cord of the main chute are straightened. This period of time is less than 3 s, so the simulation time is identified as 3 s.
