Test and Evaluation of an Experimental Feasibility Prototype Passive Seat Mounted Limb Restraint System

摘要

An experimental feasibility prototype of passive seat mounted limb restraint system was tested under various conditions both statically and dynamically on the NAVAIRDEVCEN Ejection Tower and the Dayton T. Brown windblast facility. The Ejection Tower tests resulted in successful and repeatable entrapment of the arm and legs, and good tensioning of the restraint lines through one-way snubbers. The windblast test series also resulted in successful entrapment of the limbs at various pitch and yaw angles up to 600 knots. The results of this T&E study clearly showed the feasibility of the system to provide the necessary protection to the crewmember during the simulated operation environments, and also to meet the passive requirements which results in no additional encumbrances on the crewmember.
