Abstract:

This is an analysis of the crashworthiness characteristics of a standard litterpatient 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 litterpatient restraint system failed. It is concluded that the military specifications covering litterpatient restraint systems are not realistic and, therefore, litterpatient restraint systems produced in accordance with these specifications do not provide adequate protection for the occupant under moderately severe, but potentially survivable, crash conditions.
