Abstract

A release device, and in particular a release device for use in parachute systems in place of pyrotechnic cutters. The inventive systems utilize a severable structural member of low melting point, high strength polymer that is severed by introducing a heat defect. The member is typically a ultra high molecular weight polyethylene braided line and the heat defect is preferably caused a resistance heater or solid state laser diode. This inventive results in a low cost non-pyrotechnic release device with is not subject to regulatory and transportation restrictions.
