Debris Intrusion Shield for Jet Engine Applications

摘要

The Debris Intrusion Shield for Jet Engine Applications is a prolate hemispheroid metallic assembly installed at the intake of a jet engine. The assembly is designed and intended to limit or prevent the intrusion of solid or semi-solid objects into the engine intake while on the ground or in-flight. All elements of the assembly are arrayed symmetrically about the longitudinal axis of the engine. The assembly is constructed of four basic parts. Tubing is positioned as a radial array about the engine circumference, and serves as the primary debris deflection element. The engine mounting collar serves as the aft point-of-attachment of the assembly to the engine nacelle, and as the aft mounting point for the radial array of tubing. The forward mounting fixture serves as the forward point of connection for the tubing elements. The forward mounting fixture cover serves as a protective cover for the electrical anti-icing elements located at the forward surface of the forward mounting fixture.
