为了解决火箭橇试验橇体运行高精度的时空位置测试难题,提出了遮光板时空位置测试方法,主要围绕该测试方法展开,提出了整体设计思路,并就光电组件设计、橇载数据记录仪设计、遥测系统设计、遮光板设计及其布设方法、遮光板靶距测量方法、数据处理方法等方面进行了论述。设计人员开发研制了相关产品,并通过多发试验验证,取得了良好的测试数据。该方法测试精度高,可以满足惯性测量装置功能和精度考核试验,使用前景广泛。

In view of difficulty in high-precision test of time and position in rocket sled test, shading plate position and time testing method was presented. Based on the method, overall design idea, photoelectric component design, sled borne data recorder design, telemetric system design, shading plate design and layout method, measurement methods from the shading plate, target data processing method and other aspects were discussed in this paper. Designers developed related products, tests prove that the test data obtained is good. The method can achieve high testing precision, and can meet inertial measurement unit function and accuracy test, it is prospective.
