C/C composite material is widely used as the insulation material since its advantage is obvious compared with other materials. It is necessary to evaluate its ablation, especially when it used in the warhead. An ablation/erosion test system based on plasma is researched. All the parameters related to the plasma can be monitored by it to calculate the enthalpy. Two ablation tests of the C/C composite material are carried by this system. The ablation of the carbon fiber and the erosion of the particle are mainly analyzed by the measure of the ablation rate and the SEM photos.

The Future

Nowadays, various test equipment tend to be more intelligent, the test equipment of the volt-ampere characteristic of CT is so too. As the development of the electronics, VLSI(SCM) is manufactured. The purpose of our project is to scheme out a intelligent test system by the computer technique and the test technique. This equipment is mostly made of the SCM system and the peripheral equipment. We control the output of the digital transformer by SCM. The output voltage can make the TL494 create PWM wave. The wave is the control signal of the main circuit. The output wave of the main circuit is the sine wave, and the value of the output can be amended automatically. Compared with the traditional equipment, this equipment is smaller and use less energy, but its function is more powerful. It can be programmable. We can take it more expediently. So, this kind of equipment can be used widely in the future.

The Impact

According to the technical requirements of harsh shock environment test, this paper presents the study on the pneumatic vertical test technology with large load and high-g value. The inspiration of this paper comes from the fact that a compressed air cannon can produce instantaneous and powerful air jets that can be used to drive the tested object to achieve a high initial collision velocity. Then, the principle of shock test technology based on an air cannon and an impact cylinder was put forward, and the idea gas mechanics model was established to theoretically analyze the laws that how the parameters of the air cannon and cylinder influence the initial impact velocities. The test system was built, and the test research was carried out. When the air cannon pressure is 0.5 MPa and 0.65 MPa, respectively, under no-load, the impact acceleration measured is 1990 g (pulse width, 1.26 ms) (1g = 9.8 m/s2) and 4429 g (pulse width, 1.20 ms). It preliminarily validated the effectiveness and feasibility.
