Inflight recovery or escape from a disable helicopter requires that the rotor blades not interfere with the orderly operation of the emergency system that will return the occupants safely to earth. the objective is to present a methodology for removal of the rotor blades in a controlled manner to… More

Some of the advantages of the SPINAL PRE-LOADING CATAPULT are given and the theoretical basis for its design is provided. The results of a study indicate improved performance levels that can be expected from the Spinal Pre-Loading Catapult are discussed. Utilization of a computer model of a… More

Shock waves which form forward of an occupied ejection seat in a supersonic airstream can produce static and total pressure values which indicate safe altitude/airspeed conditions suitable for recovery parachute operation when in acutality, extreme high altitude/airspeed conditions still exist. A… More

During a crash of a troop-carrying fixed wing aircraft or helicopter the troop seats have been designed to withstand the specification force levels without regard for any protection of the seat occupant's spine. A recent troop seat redesign program has resulted in a seat design that provides some… More

Small, light weight, female pilots have been introduced into the AF and Navy pilot population in recent years. The increased spinal loading of light weight ejectees during the catapult stroke, with its attendant increased probability of spinal injusy, that occurs in an ejection is well known. It… More
