Extended Measurements of Aerodynamic Stability and Limb Dislodgement Forces with the ACES-II Ejection Seat

Abstract

The ACES-2 seat was mounted in a wind tunnel in various attitudes of pitch and yaw. The hand and foot rests were equipped with means to measure limb dislodgement forces. Overall forces and moments were measured at the seat mount. Human subjects were used as seat occupants for gross force and moment data on the seat/occupant combination, as well as limb dislodgement force measurements. Anthropomorphic dummies were used for an extended range of yaw angles around to 180 degrees. Only gross force and moment data for the seat/ occupant combination were taken with the dummy subjects. The limb dislodgement results are complementary to earlier tests at low pitch angles and show general reductions in magnitude as the pitch angle is increased.
