摘要：During the development of thermal protection materials for hypersonic vehicles, the simulated ablation test based on thermal plasma has been widely used. In this paper, a small plasma multi-phase flow simulation ablation test system is designed based on the automatic control technology. After the overall design, hardware processing and software development are completed. Then the system parameters are calculated and tested by numerical calculation methods and heat flow densitometers as well as other test instruments. The results show that the system has high enthalpy, high temperature and high heat flux, and solid particles can be injected in it to simulate particle erosion effects. The system can generate plasma jet with continuously adjustable parameters. The stagnation point temperature is 11651 K and the central speed is 1222 m•s−1. The particle addition rate is continuously and adjustable. The maximum speed in the experiment is 280 m•s−1, and the surface temperature is about 2650°C. The work in this paper provides an important way for more inexpensive and efficient ablation tests of thermal protection material. The results provide a useful reference for the selection of the relevant material's ablation test parameters.
