Abstract Text:
The main thrust of the program was directed toward two objectives: (1) development of apparatus for the measurement of ignitability characteristics of fluids at high temperatures (up to 930 C), and (2) the use of that and other apparatus for the determination of ignitability, flame propagation properties, and heats of combustion of a number of aircraft fluids. These included currently used hydraulic fluids, candidate nonflammable hydraulic fluids, and other aircraft fluids such as lubricants, fuels, and heat transfer fluids. The studies were successful in the identification of candidate nonflammable hydraulic fluids. These fluids were identified as Halocarbon AO-8, Freon E6.5, and Brayco 814Z. A semiautomatic ignition test apparatus was built that can be used for measurements at temperatures up to 1000 C. The operation range of a hot manifold ignition test apparatus was extended up to 930 C.

Abstract Text:
The dynamic surface ignition characteristics of aircraft fuels and hydraulic fluids were investigated on heated stainless steel and titanium surfaces. Local air flow (0.8 to 50 meters per second) (2.4 to 152.4 ft/sec) effects were measured. aircraft fuels evaluated on titanium surfaces ignited (25 to 75 C) (77 to 167 F) lower (500 to 600 C) (932 to 1112 F) than values required to ignite the fuels on a heated stainless steel surface. Higher local surface air speeds necessitated higher surface temperatures for ignition of an applied fluid. The same trends were noted for hydraulic fluids sprayed on the heated surfaces.
