A diverterless engine inlet system that integrates a "bump" surface with a forward swept, aft-closing cowl to divert substantially all of the boundary layer air from the inlet. The bump includes an isentropic compression surface raised outwardly from the body of the aircraft to form a portion of the inner surface of the inlet. The cowl couples to the body of the aircraft to form the remaining surfaces of the inlet and closes against the body of the aircraft at the aft-most points of the inlet opening. The bump and the cowl work together to divert low energy boundary layer air from the inlet during aircraft operation, thus eliminating the requirement for a boundary layer diverter. The diverterless inlet provides a lower cost, reduced complexity air induction system that can be used on a supersonic aircraft engine.

[ What is claimed is:] [1.] A system for diverting boundary layer air from an inlet for an aircraft engine comprising:a bump having a surface raised outwardly from the body of the aircraft to begin diverting the boundary layer air from the inlet prior to the boundary layer air entering the inlet, the bump beginning prior to an opening of the inlet and extending toward the rear of the inlet to form at least a portion of an inner surface of the inlet; anda cowl coupled to the body of the aircraft to define the opening of the inlet comprising;an aft-closing portion closed against the body of the aircraft at the aft-most points of the opening of the inlet; anda forward-swept portion, coupled to the aft-closing portion, that extends toward the front of the aircraft;the cowl working in conjunction with the bump to further divert the boundary layer air and prevent substantially all of the boundary layer air from entering said inlet during operation.
