Wind Tunnel Measurements of Vertical Acting Limb Flail Forces and Torso/ Seat Back Forces in an ACES-II Ejection Seat

Abstract

In the study of flail injury (References 4 and 5 ) it is important to know the magnitude of the forces tending to pull a crew member's limbs away from their 'stowed' position, when he first ejects into the windblast. Earlier wind tunnel studies did not record the limb lift component force for the hands or feet. These forces, along with the drag force between the occupant and the seat, were measured in this investigation, for the range of pitch and yaw angles used in the previous investigations of other force components. The results and their implications are presented and discussed.
