Abstract

The invention discloses a turbofan engine inlet part ice ball collision device and belongs to the technical field of aeronautical facilities. The device comprises a gas storage tank, a locking air cylinder, a cabin inner sliding valve, an ice ball filling emitting cabin, an ice ball emitting pipe, an ice ball supporting rod, an ice ball inlet, a sliding valve groove, an ice ball inlet sliding valve and a handle. An inlet of the ice ball emitting pipe is connected with the ice ball filling emitting cabin. The cabin inner sliding valve and the ice ball supporting rod are arranged in the ice ball filling emitting cabin. The locking air cylinder is arranged outside the ice ball filling emitting cabin and is connected with the cabin inner sliding valve. The ice ball inlet and the sliding valve groove are formed in the same side wall of the ice ball filling emitting cabin. The ice ball inlet sliding valve is arranged in the sliding valve groove. The handle and the ice ball inlet sliding valve are fixedly connected together. Impact force on ice balls is generated by controlling high-pressure gas, so that the ice balls fly to a target at high speed, and the effect of ice ball collision is achieved. The testing device is simple, parts can be easily purchased or machined, the whole device is easy to implement, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of aviation equipment, and specifically relates to an ice bomb impact device for an inlet part of a turbofan engine that generates impact force on an ice bomb by controlling high-pressure gas, thereby causing the ice bomb to quickly fly 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...
