Diverting boundary layer air

摘要

A diverterless engine inlet system (10) integrates a transition shoulder into a system for diverting air from the inlet of a jet aircraft engine. A bump (20) 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 transition surface works with the compression surface to divert low energy boundary layer air from the inlet during aircraft operation.
