| Abstract: | The anti-interference technique of measuring system and its usage in the LOX /kerosene engine test is studied. They are insulation technique, filter technique, long wire trans- mission technique, grounding technique and anti-interference technique of power supply system. The obtained basic knowledge of interference has been combined with the design and installation of measuring system of LOX/kerosene rocket engine test bed. The hot run tests indicate that the measuring system operation is stable and credible, the measured data are valid and accurate,and the SNR(Signal Noise Ratio) of the measuring system is better than 50dB. |
