Aircraft Fuel System Tests with Gelled Fuel-Flowmeters Calibration, Fuel Boost Pump and Jettison Tests.

Abstract

The feasibility of using gelled fuel (nominal 250 centipoise viscosity) with full scale aircraft fuel system components was investigated. Tests indicated that turbine-type flowmeters are suitable for measuring flow rates with accuracies of one percent. Jettison and fuel feed operations were conducted using a B-57 wing fuel tank. Approximately three percent more gelled fuel than JP-5R remained in the tank after emptying the tank in both boost pump and jettison tests. Flow rates and times to empty the tank were significantly poorer with the gelled fuel when compared to the results obtained with the JP-5R fuel. The gelled fuel tested is considered unsatisfactory because of its instability in storage, causing wide variations in viscosity. (Author)
