| Abstract: | In this paper,the design principle,structure features and the accuracy analysis method of a test system with accuracy of 0.5% for solid rocket engines are introduced. The system shows rational design and stable and reliable operation during a long abjustment at static state and firing tests and has been approved by the Ministry of Aerospace Industry. The accuracies of the system respectively are 0.2% on static thrust calibration, 0.05% on thrust zeroing, less than 0.3% on relative thrust uncertainty and 0.01% on three year stability.
The comprehensive design idea combining electric and mechanic parts, the development and the application of AD-1 precision data amplifier and simulating signal generator, and the programing method including man-machine communication are also discussed in this paper, which will be used to develop the stable, reliable and high precision test system. |
