ABSTRACT:
An oil scavenging system for a main shaft bearing in a gas turbine engine includes a sump adjacent the bearing having a frustoconical inner surface and a constant diameter inner surface contiguous with the frustoconical surface. The small diameter end of the frustoconical surface is adjacent the bearing and the latter includes a low efficiency pumping member which pumps the oil onto the frustoconical inner surface with high tangential velocity. The oil centrifugally adheres to and migrates along the frustoconical surface and has sufficient tangential velocity to also centrifugally adhere to the constant diameter surface. The oil adhering to the constant diameter surface drains into drain entry in the constant diameter surface and is collected by a single scavenge pump pick-up regardless of engine attitude or altitude.
