Scavenging Engine Oil Pumps for Oil Service - J57 TF33 Series Engines.

Abstract

Static oil drain-down occurring between the postflight inspection and next flight can fill the N2 oil pump and accessory housing on J57 and TF33 jet engines to a point where it drains overboard on the ramp. This can deplete the oil supply, resulting in launching of aircraft with less than full oil quantity. The purpose of this test was to evaluate a method of turning over an engine with the starter to rotate the gear type oil pumps and scavenge oil back to the tank. For testing the N2 gearboxes were filled to their maximum capacity with oil. The engines were then motored with the starter for two minutes and checked for residual oil quantities. (Author)
