Lateral (-Gy) Impact Tests with Inflatable Restraint Systems for Air Force Crew Escape Module Applications

Designers of emergency escape capsules cannot meet current Air Force biodynamic limits describing tolerable impacts encountered during the escape sequence. A major reason for this is the lack of an efficient lateral body support system. The objective of this program was to demonstrate the feasibility of using an inflatable restraint system in crew escape modules for lateral impact protection. Tests were conducted on both dummy and human subjects. Human impact tests using the restraint inflated to 8 psi were conducted up to 15.6 g without reaching a subjective tolerance endpoint. The conclusion was reached that the prototype system would improve lateral impact protection and that it was compatible with the crew escape module recovery sequence.
