Abstract : A test series was initiated investigating aerodynamic heat up of fuel system vapor space in terms of pressure level, heating rate and mixture composition. Tests were conducted at pressure levels from 2 to 15 psia and with JP-6 fuel vapor-oxygen-nitorgen mixture compositions containing from 20 to 2% oxygen by volume. In all tests conducted reaction of the mixture was indicated. Significant test results include the following: (1) In tests with 2% oxygen concentration and within the pressure range investigated, reactions are predominantly of the cool flame, slow oxidation type. (2) Severity of reaction decreases considerably as the mixture becomes increasingly fuel rich. (Author)
