Abstract

Transient loss of cabin volume, observed during full-scale crash tests of small airplanes, has been advanced as the cause of damage to test dummies during test conditions predictive of injury to restrained occupants during accident conditions. The purpose of this study was to review the results of National Aeronautics and Space Administration (NASA) Test 7 and assess the correlation between transient loss of cabin volume and test dummy damage. The results of this study show that the only correlation was that both occurred because of the severe impact conditions of the airplane during the test sequence. The forward and vertical components of velocity change at the centre of gravity of the airplane in NASA Test 7 equal to 15.46 and 13.66 m/s exceeded the small airplane design conditions for which it is possible to prevent injuries to the head, chest, and spine of restrained occupants.
