Abstract

The invention discloses a turbofan engine inlet part birdshot impacting device, and belongs to the technical field of aviation equipment. The turbofan engine inlet part birdshot impacting device comprises an air storage tank, a locking air cylinder, a cabin sliding valve, a birdshot filling launching bin, a birdshot launching pipe, a birdshot supporting rod, a birdshot inlet, a sliding valve groove, a birdshot inlet sliding valve and a birdshot shell stripper, wherein the inlet of the birdshot launching pipe is connected with the birdshot filling launching bin; the cabin sliding valve and the birdshot supporting rod are arranged in the birdshot filling launching bin, and the locking air cylinder is arranged outside the birdshot filling launching bin and is connected with the cabin sliding valve together; the birdshot inlet and the sliding valve groove are both arranged on the same side wall of the birdshot filling launching bin, and the birdshot shell stripper and the outlet of the birdshot launching pipe are connected together. The turbofan engine inlet part birdshot impacting device provided by the invention has the advantages that impact force is generated for a birdshot by controlling the high pressure gas, the birdshot rapidly flies to a target, and a birdshot impacting effect is realized; and a test device is simple, a part is easy to purchase or process. The whole device is easy to implement, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of aviation equipment, and specifically relates to a birdball striking device for an inlet part of a turbofan engine that generates an impact force on a birdball by controlling high-pressure gas so that the birdball quickly flies to a target. Background technique [0002] The full name of the turbofan engine is a turbofan engine, which is a type of aircraft engine developed from a turbojet engine. Compared with the turbojet, the main feature is that the area of ​​the first stage compressor is much larger, and it is also used as an air propeller, pushing part of the sucked air back through the periphery of the jet engine. The part through which the air of the core part of the engine passes is called the inner duct, and the outer part of the core engine through which only the fan air passes is called the outer duct. Turbofan engines are most suitable for use at a flight speed of 400 to 1,000 kilometers, so mo...
