An Investigation With Human Subjects into the Potential for Dynamic Preloading of the Spinal Column To Improve Escape System Performance.

Abstract

Tests were conducted at AL/CFBE using human volunteers on the Vertical Deceleration Tower. The tower was modified to provide an impulsive deceleration to the seat prior to the carriage pin striking the water in the cylinder. Measurements were made of seat pan forces, head acceleration, and chest acceleration. Each volunteer was subjected to three test conditions: Cell A was a 6 G pulse, with no preload; Cell B was an 8 G pulse with a 10 G preload; and Cell C was an 8 G pulse with no preload. The calculated Dynamic Response Index and measured physical responses of the volunteers confirmed that dynamic preload was effective, reducing the injury potential of Cell B nearly to that of Cell A.
