Large aircraft engine thrust reverser and its applicationAbstractWith the development of science,China's aviation industry continues to progress.In thepast ten years,we can find that China's civil aviation industry has developed very fast.On thesurface,the aircraft types are increasing,which means that one aircraft can carry morepassengers,and the flight time is constantly shortened,which indicates that the speed of aircraftflight is increasing,and the development of aircraft research has new achievements.However,with the increase of flight speed,the glide distance when the aircraft lands will also increase.Ifwe don't speed up the deceleration,as the speed of the aircraft increases,the taxiing distance ofthe aircraft when it lands or stops taking off will also increase.This is related to a practicalproblem,whether the airport site can meet the aircraft's running distance.So we need to studywhat are the deceleration systems of the aircraft and what benefits the engine thrust reverser canbring to the aircraft.The main content of this paper is through the research of the thrust reverser of aircraftengine:the working principle,type and application example of the thrust reverser.1.Development of thrust reverser;2.Main types of thrust reverser;3.Requirements of thrustreverser;4.Application examples of thrust reverser;as well as the impact of air flow on aircraft,study the advantages of thrust reverser relative to brake system,analyze the disadvantages ofthrust reverser and how to avoid them.This problem can be effectively solved by using thebackstepping device.Key words:Engines Thrust revers ApplicationsII
