Abstract:A numerical simulation for the process of airdropping for the disaster relief at a super low altitude by using the dynamic finite element method was made. The computational model of the airdrop process was developed, and the typical conditions of real airdrop and its process were simulated. The security of airdrop, the loading impact and the decelerating effect were analyzed based on the simulation results. It provided theoretic basis for the design of the super low altitude airdrop, and a new validating method for evaluating the feasibility of the project and the reliability of airdrop process was presented.
Keywords:super  low  altitude airdrop  deceleration  simulation  finite element
