Embodiment Construction
[0023] refer to figure 1 , making a plasma thruster thrust vector measurement device, the device includes: 1. Electrostatic probe, 2. Insulation sleeve, 3. Probe support seat, 4. Sampling resistor, 5. Bias power supply, 6. Data acquisition device , 7. Reference electrode, 8. Positioning piece, 9. Shock absorbing piece, 10. Movable platform, 11. Rotary table.
[0024] In this embodiment, the electrostatic probe 1 is made of a tungsten wire with a diameter of 0.3mm, and extends out of the insulating sleeve 2mm. The outer diameter of the insulating sleeve 2 is 1mm, and the length is 35mm, so as to reduce the disturbance to the jet flow as much as possible. The thin tungsten wire diameter makes the measurement results have a higher spatial resolution; the probe support seat 3 is made of high-temperature resistant ceramic material; the bias power supply 5 is set to 10V, the resistance of the sampling resistor 4 is 1 ohm, and the data acquisition The device 6 is a digital oscillosc...
