Abstract
An aircraft engine starter assembly has a starter motor, a notch containing plate rotationally coupled to the starter motor or the aircraft engine, a strut pocket containing plate rotationally coupled to the other of the starter motor or the aircraft engine, arranged facing the notch containing plate and spaced apart therefrom by an inter-plate space, wherein the strut pocket containing plate has a spring loaded strut mounted in at least one pocket thereof, aligned to engage a notch as the two plates rotate with respect to each other about a common centerline, so that the strut engages the notch to start the engine and releases from the notch when the engine is running. A lube oil pump is provided to force oil into the inter-plate space and bearings are provided coupled to the two plates to react the expansion forces created by the pressurized lube oil.
