Abstract : At elevated temperatures, hydrocarbon jet fuels tend to form deposits which decrease heat exchanger efficiency and plug screens and filter elements. In order to quantify this tendency so that it may be predicted, it is necessary to obtain comparative test results on a simulated aircraft fuel system and small-scale test devices. In the report, the thermal stability of the second fuel (AFFB-9-67) tested in the Advanced Aircraft Fuel System Simulator is quantified in terms of the amount of deposit formed. The quantification of deposit formation is determined under cyclic conditions (mission profiles) and two types of steady state test conditions (steady state and steady state-varied flow). The difference between the two steady state tests is that the steady state test was performed at constant flow rate and heat input and the steady state-varied flow test contained intervals wherein a higher flow rate and no heat input were imposed. In addition to testing in the Simulator, fuel AFFB-9-67 was tested in the standard, gas, research, modified, and micro cokers; as well as other facilities. (Author)
