Abstract

The invention relates to a protective cover for protecting the worm fan engine of plane, which comprises a frame (1) at the front of engine (A), a gas hole (2) on the frame (1) to guide air, a fixing belt (3) at the end of frame 91) to fix the frame (1), a bolt hole on the fixing belt (3), and a support (5) inside the frame (1) to connect the inner wall and support the frame, wherein there are two gas holes (2A, 2B). The frame (1) can reduce the air resistance and improve the anti-impact ability; the gas hole (2) can supply air to the engine (A); the fixing belt (3) and bolt hole (4) can fix and connect the protective cover and engine (A); and the support (5) can strengthen the frame.

Description

Technical field: [0001] The invention relates to a protective cover for protecting the safety of an aircraft turbofan engine, which comprises a casing installed on the front end of the engine to block impact objects, an air guide hole arranged on the casing to conduct air, and a casing arranged on the casing The end of the body is used to connect the fixing belt with the engine, the bolt hole is arranged on the fixing belt, and the support frame used to support the casing is arranged in the casing. Background technique: [0002] The engine is an important part of the aircraft, it provides flight power for the aircraft, and its operating status is crucial to the safety of the aircraft and people. Over the years, accidents of engine damage due to the impact of air impactors have occurred from time to time, such as flying birds, hail, etc., and its consequences are very serious. From the perspective of aircraft structure, the front protection of the engine is the weakest, and ...
