摘要
以目前国内唯一可进行发机装机状态下推力测试的试验设备为研究对象,介绍了其全机推力试车台的台架总体结构及飞机装机推力测量方式,重点对推力测量系统及其校准方法进行了详细描述,分析了全机推力测量的影响因素、测量结果修正方法及目前校准方法存在的不足,提出了装机校准、左右平台联合校准、伺服加载校准和原位校准等多种改进措施,提高了全机推力测量系统的校准准确度以及发动机装机推力的测量准确度,对于其他同类设备的校准也具有重要的参考和借鉴价值。
This paper introduces the overall structure of aircraft-engine test cell and the thrust measurement method of engine installed on aircraft. The thrust measurement system and calibration method are described in detail. It analyzes the influence factors of the aircraft-engine thrust measurement,the correction methods of the measurement results and the shortcomings of the current calibration methods. Several improvement measures such as installation calibration,left and right platform joint calibration,servo loading calibration and in situ calibration are proposed. The calibration accuracy of aircraft-engine thrust measurement system and the measurement accuracy of engine installed thrust are improved. For other similar equipment calibration also has important reference and reference value.
