TRAJECTORY OF THE PUNCHING QUICK AIRDROP AIRBAGS IMPACTED BY THE GUST

How to make the effect of the airdrop equipments af fected by the turbulent airflow minimum, and realiz e the fixed-point and precise airdrop, is a problem t hat has been plagued by the domestic and foreign experts.The article makes the mesh generation of th e airdrop airbag model, builds the finite element simulation models, and uses finite element analysis software ANSYS/LS-DYNA to study the falling process of the punching quick airdrop airbags. Thro ugh the simulation of the falling process, the pape r gets the status parameters of the airbags, and analyzes whether the airbags meet the falling demands or not . Then this article researches the airdrop trajectory of the airbags with gust and no gust, and research es the airdrop trajectory of the airbags under horizontal and vertical gust. In order to reduce the effect of the gust on the airdrop trajectory, the paper puts forward t he controlling strategy.
