Abstract:

Fourteen fire tests were conducted with a surplus, fire-hardened DC7 fuselage positioned adjacent to a 20-foot-square JP-4 fuel fire. The fuselage had a door opening at the center of the fire and door openings displaced from the fire on each side of the fuselage. Temperatures, light transmittances, and heat fuxes were measured for each of these 90-second tests. The opening of doors away from the fire was varied from test to test as was the ambient wind velocity. Wind direction coupled with the door opening configuration were found to be controlling factors in the accumulation of heat and smoke within the aircraft cabin. Heat fluxes into the cabin through the fire door also changed significantly with wind and door openings and depended on the degree of flame penetration through the fire door. When flames did not penetrate into the cabin, the symmetry plane heat flux at the fire door station agreed very well with earlier modeling predictions. Author
