Abstract
Abstract : A theoretical study was performed to evaluate the thermal performance of the Air Force C-9 personnel parachute and various parachute materials during encounters with JP-4 aircraft crash fires. The objectives of this study were to Develop an analytical model of a parachute encounter with a fire; determine what parameters are critical to thermal response; provide a relative measure of thermal performance of Nylon, Nomex and PBI; assess the range of failure conditions. These were accomplished by developing a computer model of the crash fire, the parachute material and configuration, and the trajectory simulating the heating and thermal response of a parachute during descent. With regard to the three fabrics considered, both Nomex and PBI exhibit improved thermal tolerance over Nylon, retaining strength to several hundred degrees (F) above Nylon.
