Abstract:

The report covers the design, development, and the U.S. Navy Service Qualification Program conducted on the NES-21A personnel parachute assembly designed for use in ejection seats of U.S. Navy T-33B and QT-33A aircraft. The NES-21A design objective was to provide a retrofitable replacement for the existing NS-3 personnel parachute assembly which would operate with a decreased opening time. This factor would improve aircrew survivability in the low speed, zero altitude operational envelope. This improvement was accomplished principally by the incorporation of a 40-inch diameter internal pilot chute and main canopy PDVL Pull Down Vent Lines. The NES-21A parachute assembly will perform satisfactorily as presently designed at 90 KTAS Knots True Airspeed and above, for ground level and higher altitude ejections.
