Abstract:

Airbags are currently being investigated as a ground impact energy absorber for U.S. Army airdrops. Simple airbags with constant vent areas have been studied previously by numerous investigators. In this research effort, a method of controlling the vent area and a method of injecting gas into a simple airbag to improve its performance, i.e., to decrease its peak C force, were analytically and experimentally investigated. In addition, augmented simple airbags using paper honeycomb as an auxiliary energy absorber were also experimentally investigated. Complex airbags using vent-control and gas- injection and augmented airbags were found to decrease the peak G forces of simple airbags by 30. Results of these investigations are presented in this report. Test and evaluation, Airbags, Impact attenuation, Energy absorbers, Soft landing, Airdrop Operations, Ground impact.
