Abstract:

Aerodynamic and biomechanic analyses are presented for a fighter seat and escape system. A semi-enclosed seat configuration is described that provides pilot protection for ejections at a dynamic pressure of 2000 psf, well beyond the capability of existing open-seat ejection systems. Increased ejection performance is achieved by taking advantage of a pronated forward-leaning seat configuration to increase pilot protection from windstream deceleration forces, and provide stability in the windstream prior to deployment of the drogue chute. These enhancements, in conjunction with the increased pilot g-tolerance during flight described herein, make the concept of a pronated fighter seat very attractive. A computer model of pressure distribution on panels was used to predict aerodynamic forces and moments. computer simulation of ejection dynamics was used to predict dynamic stability.
