Abstract:

Crashworthy troop seat designs developed under a previous contract were reviewed and design refinements were made. Component testing was planned and tests were performed. Malfunctioning components were redesigned and were retested satisfactorily. A new tubular-strut energy attenuator was developed to replace the rolling helical-wire energy attenuator which did not function properly. Crashworthy troop seats fabricated under a previous contract were modified, with new components developed during component testing. Additional seats were fabricated for static testing in various crash impact attitudes. A total of six static tests, including two retests required as a result of minor failures, were performed by Dynamic Science as a subcontractor. Analysis of the test results showed that the forward- and aft-facing seat configurations were highly successful in meeting the test objectives in all attitudes, with the exception of the lateral loading. Eleven dynamic tests were performed by FAA- Civil Aeromedical Institute in three series of tests.
