Abstract

The invention discloses a device and a method for testing ablation resistance of a fluid director, the device comprises a rack, a gas generator is arranged in the middle of the rack, the fluid director and a test bench for supporting the fluid director are arranged right below the gas generator, and a plurality of temperature sensors are arranged on the fluid director; a plurality of pressure sensors are arranged between the periphery of the bottom of the fluid director and the top of the test bed, signal output ends of the temperature sensors and the pressure sensors are respectively connected with a signal input end of an external control center, and a control signal input end of the gas generator is connected with a control signal output end of the control center. The device for testingthe ablation resistance of the fluid director is simple in structure, convenient to use, high in simulation trueness, convenient in data acquisition and capable of well meeting test requirements.

Description

technical field [0001] The invention relates to the technical field of performance testing of a deflector, in particular to a device and method for testing the ablation resistance performance of a deflector. Background technique [0002] With the rapid development of the aerospace industry and weaponry, various products need to be effectively guided by high-temperature and high-speed airflow when launching, and the demand for deflectors is increasingly strong. During the launching process, the gas flow is rich in various chemical substances and solid particles, which will have a severe impact effect and ablation effect on the deflector. At the same time, the vehicle deflector generally requires light weight, so the low-density, high-strength, The ablation-resistant non-metallic protective cover can be quickly replaced after the service life is reached to ensure the needs of the launch mission. [0003] How to test the ablation resistance of the non-metallic protective cover...
