DYNAMIC TEST OF AN AIRCRAFT LITTER INSTALLATION

Abstract

This is an analysis of the crashworthiness characteristics of a standard litter/patient restraint system as installed in a helicopter which was subjected to a dynamic crash test. Several personnel restraint systems were installed in the aircraft to permit evaluation of performance under impact conditions. Included was a standard litter installation. Anthropomorphic dummies were placed on the litters. Accelerometers were mounted in the pelvic areas of the dummies, and tensiometer links were mounted on the litter support straps. A high speed camera was positioned in the helicopter to record the action of the litter installation during the crash sequence. The crash was considered to be survivable, but the litter/patient restraint system failed. It is concluded that the military specifications covering litter/patient restraint systems are not realistic and, therefore, litter/patient restraint systems produced in accordance with these specifications do not provide adequate protection for the occupant under moderately severe, but potentially survivable, crash conditions.
