Small Aircrew Ejection Simulation in U.S. Navy Aircraft.
Abstract
With the Navy's recent expansion of the aircrew population to include a greater percentage of aviators, both male and female, the accommodation of small aircrew has become an important issue. All ejection seats currently used by the Navy were designed and test qualified for male aircrew ranging in weight from 135 lbs to 212 lbs. None of the Navy ejection seats have been test qualified for flight by aircrew smaller than a 135 lb male. It is expected that such aircrew will be subjected to higher risk of injury in the event of an ejection. Naval Air Warfare Center, Aircraft Division, Warminster has conducted simulations to predict the risk of injury in small aircrew ejections in each of the seat systems currently in the fleet. Simulations of NACES, SJU-5, SIIIS, ESCAPAC IE-1, GRU-7, and LS-lA ejections with aircrew both within and below the seat design weight ranges have been completed. The calculated risks to 100 lb and 116 lb female aircrew in ejections at speeds from 0 to 600 KEAS were examined as were the calculated risks to aircrew at the limits of the design weight range in identical ejections. This paper documents the results of the simulation effort.
