The cushion airbag is widely used in military equipment, relief supplies airdrop, spacecraft recovery, automobile safety airbags and so on. Damage of supplies and injury of crews can be effectively avoided with airbag of good cushion performance which reduce the force and load of impact. Based on reference of a certain airdrop airbag system, a research of cushion process is presented by the use of LS-DYNA simulation software and Control Volume Method to simulate cushion process of the airdrop airbag system numerically. With engineering calculation and tests, a design concept and method of airbag system with a subsidiary airbag is achieved, which makes the cost and time of design and development reduced.
