某型涡扇发动机试车台测试系统研制

Development of the Test System for Some Model of Turbofan Engine Test Platform

结合某型高推重比涡扇发动机试车合测试系统的研制，介绍了该系统的技术指标、数据采集技术、显示技术和试车仿真原理。为提高系统测量精度和使用性能，提出并应用了测量参数非线性修正、多模式显示、实时发动机参数整理等技术。

Combining the development of the test system for the testing platform of some modelhigh thrust-weight ratio turbofan engine, the technique index, data acquisition technique, displaytechnique and simulation principle of test run of the test system are described. In order to increase theprecision of measurement and enhance the use performance of this system, the method of nonlinearcorrection of parameter measured, multiple mode display, real-tirne engine parameter calculation andanlysis etc. are suggested and applied.
