It aims to improve the airdrop structure design and the main materials, thus to improve airdrop landing buffering effect and upgrade the reliability of the drop. With airdrop platform structure and material as the research object, cushioning packing materials were selected reasonably and the design of airdrop platform structure was optimized by the airdrop experiment. The three-layer buffer structure (upper, middle and lower) was worked out and materials for each layer were properly determined. The improved airdrop platform had greatly upgraded reliability. In conclusion, the improvement of airdrop platform structure design and cushioning materials can meet the requirements on middle-sized pack airdrop, guarantee the intact and normal use of airdrop supplies and improve the stability and impact resistance of airdrop platform structure.
