Abstract

An engine oil system (34) for an aircraft engine includes an oil tank (68) and an oil tank return (78). The oil tank (68) forms an internal oil cavity (74). The oil tank return (78) forms a portion of an oil flow path (64) through the engine oil system (34). The oil tank return (78) includes a return body (80) forming a return passage (88) extending between and to a passage inlet (90) and a passage outlet (92). The return body (80) includes an inner diameter wall (106) and an outer diameter wall (108). The inner diameter wall (106) and the outer diameter wall (108) form a turn (104) of the return passage (88) between the passage inlet (90) and the passage outlet (92). The return body (80) forms a top side (114), a corner (116), and an oblique side (118) at the passage outlet (92). The corner (116) and the oblique side (118) are disposed at the outer diameter wall (108). The corner (116) extends between the top side (114) and the oblique side (118).
