Aircraft Wing Fuel Tank Environmental Simulator Tests for Evaluation of Antimisting Fuels.
Abstract
The low temperature performance of antimisting kerosene (AMK) in airframe fuel systems and in certain fuel system components was studied and compared to Jet A fuel. Water vapor ingested into fuel tanks during simulation of repeated descents through clouds and rain had little effect on AMK. AMK retained antimisting properties during exposure to severe environmental flight simulations. Jet pump and boost pump operation had no discernable effect on AMK flammability. Jet pump performance with AMK was adversely affected. Main fuel boost pumps required up to 18 percent more power with AMK that with Jet A, and suction feed performance was lower with ambient and -20 deg C, but better than Jet A and -40 deg C. Boost pump performance was not affected by gel formations produced at low temperatures by the vapor removal return flow shearing of AMK. Aerodynamic heating and cooling of AMK in the fuel tank was similar to Jet A. A high pressure pump and needle valve used to degrade the AMK was inadequate, resulting in filter bypass at low temperatures. (Author)
