Tight Ribbon Arm Protection (TRAP) for Aircrewman Ejection

Abstract

When an aircrewman ejects as high speed from a damaged aircraft the windblast (high Q force) can cause arm fractures and dislocations. These injuries may be so severe that he is unable to help himself survive after the parachute descent. The TRAP (TIGHT RIBBON ARM PROTECTION) was designed to provide ejection seat arm restraint; it consists of two nylon ribbons sewn onto either side of the crewman's parachute harness (either seat-mounted or torso harness mounted). Each of these pulls down off the crewman's shoulder and automatically tightens over his arm as the ejection seat moves up into the air stream. The crewman hooks up the TRAP to snubber lines as he connects into the aircraft restraint. Initial tests indicate that the TRAP system may be able to solve the arm restraint problem.
