Abstract:
1. A jet engine intake guard system comprising: a) a cylindrical cowling in which a jet engine is mounted, said housing having intake and exhaust end; b) a bell-shaped housing coaxially mounted on the forward intake end of the cowling, said bell-shaped housing being spaced apart from the cowling by mounting bolts with a lateral space between the bell-shaped housing and the cowling intake providing air intake into the cowling intake; c) a cylindrical sliding sleeve having forward and rear openings, said sleeve being coaxially mounted in said bell-shaped housing in a telescoping manner to open and close the lateral air intake; d) means for moving said sleeve from an open position to a closed position to open and close the lateral air intake; e) a cylindrical nosepiece coaxially mounted on the forward end of the bell-shaped housing, said cylindrical nosepiece positioned on the forward or air intake end of the bell-shaped housing having an air intake opening for receiving axial flow air to the engine and having air intake ports distributed around the nosepiece's lateral surface; and, f) a conical-shaped butterfly valve mounted on the forward end of said nosepiece covering the forward or intake opening thereof, said conical valve being rotatable 180° from an open position to a close position whereby when in a closed position debris striking conical nose will be deflected away from the cowling and engine, said bell-shaped housing providing a secondary deflection for any debris striking it.
