A low-noise engine for aerospace

Abstract

The invention relates to the technical field of aerospace equipment, and discloses a low-noise engine for aerospace, including a casing, a horizontal bar is arranged on the left side inside the casing, and a low-pressure compressor is fixedly installed in the middle of the inner cavity of the casing. The left end of the low-pressure compressor extends to the inner cavity of the cross bar and is fixedly installed with a rotating rod. The left end of the rotating rod extends to the outside of the casing and is fixedly fitted with a propeller shaft. Reduction gear in rod cavity. The low-noise engine for aerospace is connected with the cross bar through the intake pipe and the air pipe, so that the air pressure difference caused by the high-speed operation of the propeller can drive the slider to reciprocate and contract, thereby slowing down the air pressure difference inside and outside the engine and avoiding the air pressure difference inside and outside the engine. Excessive pressure difference causes external pressure to drive the overall vibration of the engine, which can reduce the noise of the entire engine in terms of pressure difference.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment, in particular to a low-noise engine for aerospace. Background technique [0002] Although the development of aerospace is closely related to military applications, what is more important is the tremendous progress that mankind has made in this field, which has had a major impact on many sectors of the national economy and many aspects of social life, and has changed the face of the world Aerospace vehicles are the most important equipment in the development of aerospace. [0003] The engine in the aerospace vehicle is the final component of the aircraft. The existing aircraft engine uses fuel to make the rotor run at high speed during operation to provide flight power. Due to the high-speed operation of the rotor inside the engine, the airflow inside the engine is high The movement creates a very high air pressure difference inside and outside the engine, and at the same time, the ro...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a low-noise engine for aerospace, which has the advantages of reducing engine noise, etc., and solves the problem that the existing aircraft engine uses fuel to make the rotor run at high speed during operation to provide flight power. The high-speed operation of the rotor inside the engine causes the airflow inside the engine to move at a high speed, resulting in a very high air pressure difference inside and outside the engine. At the same time, the movement of the rotor drives the internal mechanism to vibrate at high speed, and finally makes a lot of noise, which greatly affects the passengers inside the aircraft. the rest of the problem
