| Abstract: |
| The work aims to propose a static thermal strength test method of composite bypass casing of aero-engine and consider mechanical and pressure loads in high temperature environments. The simulated structure of a typical bypass casing was taken as the test object, the designed test device and the simulated structure of a typical bypass casing were used to form a tested structure that can apply temperature load, mechanical load and pressure load, and then the temperature loading system, the static loading system and the pneumatic loading system were used simultaneously to impose the real working environment during the flight on the tested structure. The actual load conditions that affect the strength of the bypass casing can be applied simultaneously through the designed test. The static thermal strength test method proposed in this paper can replace the previous method and is generally applied to the bypass casing of metal materials, using pressure load instead of temperature load. The method proposed in this paper can be used to test composite bypass casing and provide an important basis for the weight reduction design of the bypass casing. |
