Research on airbag protection technology for ejection life-saving against windbalst at high speed

Airbag-type high-speed wind-blast protection technology is a new type of technology applied in the field of aviation, the use of the protection technology has the advantages of simple use, great protective effect and light weight. This paper presents a numerical simulation of the effect of an airbag-type protection device on the aerodynamic characteristics of the seat/occupant system. The aerodynamic characteristics of the seat/occupant system with and without deflectors, at different wind speeds, different attack angles were derived. The effectiveness of the airbag-type high-speed windblast protection is fully demonstrated.
