Live Subject Ejection Tower Testing to Determine Human Tolerance to an Increased Onset Rate of Acceleration.

Abstract

The U.S. Navy development of an advanced Minimal Envelope/Weight (MEW) ejection seat under the auspices of AIR-340, Naval Air System Command (NASC), had as one of its design goals the development of a pure rocket motor as the propulsion system. The finalized propulsion unit produced an acceleration onset of 500/G/sec which exceeded the specification maximum onset rate of 250 G/sec. As a consequence, this study was generated to determine whether the higher onset in combination with a 10 to 12 G acceleration was physiologically acceptable. This report describes the tests conducted in exploration of physiological acceptability of this particular acceleration envelope. The results indicate successful tolerance based on limited exposure of four volunteer subjects. (Author
