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.
