註釋All escape devices which have been utilized by airmen up to the present time have had the common feature of descending to the ambient terrain. They do provide a safe descent rate, but, they descend. This Proposal, Raven Industries, Inc. Number 3751 presents a unique survival system which will enable an airman to remain in the air up to thirty minutes from the time of escape to permit mid-air recovery without descending to the ground. The proposed Pilot Aerial Survival System (PASS) is based on judiciously combining state-of-the-art technologies in the fields of escape, hot air aerostats, and mid-air retrieval. PASS will follow an automiatc pre-programmed sequence from the point at which the pilot initiates escape. The first two phases of the sequence, escape and decelerator deployment, will be similar to the corresponding phases of a parachute type system. Following deployment the PASS canopy will auto-convert to form an aerostat envelope. The resultant hot air aerostat will be activated by igniting and operating an integral heat generator to provide the system bouyancy. The pre-programmed sequence will control the system to cause it to seek and maintain a specific hover altitude while awating mid-air retrieval. In the cases of complete fuel expenditure before retrieval or extremely low altitude initiation of the escape system the PASS canopy-envelope will function as a decelerator to yield a descent velocity of approximately 20 ft/sec. A five phase developmental program is proposed to culminate in the utilization of PASS in operational military aircraft. This program includes phases devoted to aerostat deployment, heat generator refinement, escape development, flight and retrieval, and rating of PASS with designated aircraft. Overall program and Phase I performance schedule, in conjunction with a cost estimate for Phase I, are included.
