Passive Airbag Vent Control Valve Study

Abstract

The U.S. Army currently uses paper honeycomb material to both dissipate the ground impact energy and to cushion parachute delivered airdropped payload from damage. This report documents exploring the use of pressurized airbags with passively controlled exhaust vents as a means to mitigate ground impact landing shock. The results of both computational and experimental research that examined the performance of passively controlled venting candidates are presented. The venting candidates studied consisted of two different linear spring check valve designs, a magnetostatic check valve design, along with two precision release blowout vents configured using a four pole magnetic valve seat design.
