Performance of Irradiated and Chemically Treated JP-5 Fuel with Inhibited Red Fuming Nitric Acid
Abstract
Gamma radiated and NALCO 305 treated JP-5 were evaluated as rocket fuels with inhibited red fuming HNO3 in a 300-lb-thrust uncooled rocket engine operated at 320 psia chamber pressure. No significant difference in performance was noted between the 2 treated fuels and the untreated JP-5 when tested under similar conditions using specific impulse as the criterion of comparison. The irradiated JP-5 was treated by immersion in a cobalt 60 gamma pool to a total radiation level of 1500 roentgens obtained at a rate of 500 roentgens/hr. Testing was performed within the half-life period of the irradiated fuel. The chemical treatment consisted of adding 0.38 ml of NALCO 305/gal of JP-5. Prior to testing, the mixture was agitated and allowed to stand for 8 hr to be certain that the additive had dispersed all the unstable fuel particles. Irradiation and chemical additives as a treatment for jet fuels was for the purpose of reducing the particle size of unstable constituents determined to be present in the fuel by the electron microscope, to improve combustion and burning rate properties of the fuel.
