An analytical study was performed to evaluate potential improvements in the thermal survivability of parachutes upon exposure to aircraft crash fires. Principal findings were that significant improvements in thermal survivability are achievable only through the use of advanced materials which, potentially, can provide survival into the flame zone. The investigation of possible design modifications indicated that alteration of fabric weight and optical properties can improve material thermal performance whereas alterations of fabric permeability are ineffective.
