    Abstract
  • The characteristics of infrared suppressing on 3-5μm band of truncated cone, which was one of the high temperature components of engine nozzle were numerically investigated. Different arrangements of film cooling gap and film cooling hole structures were disposed on the truncated cone which showing strong infrared characteristics, and cold gas flowed into truncated cone through blades from by-pass channel, causing wall temperature drop of truncated cone and blades, furthermore, the infrared radiation intensity was depressed. By comparison of the two cooling structures, it is found that the method of film cooling gaps downwards can make wall temperature and infrared radiation intensity decrease more than that of film cooling holes, while lower thrust efficiency can be gotten.
