【摘要】：随着我国低空区域逐步有序开放以及私人飞机的保有量不断增多,通用航空产业迎来了新的发展机遇。活塞式航空发动机的维修保养成为通用航空维修企业一项非常重要的工作内容,通用航空发动机性能测试任务量的大幅上涨是航空维修企业发展的必然趋势。论文以LYCOMING水平对置式全系列发动机为对象,设计一套适合于通用航空维修企业使用的、可满足多型号活塞式通用航空发动机运转参数测试、性能评估的测试系统,并编制相关实验标准及试验方法。整个系统的设计过程在满足性能测试要求的基础上,以降低制作成本,操作方便、测试耗时较短为主要指导思想。分别完成了对试车室的布置、试车台架的安装、燃油供给系、滑油冷却系以及控制系统等各系统进行了合理的方案设计和参数匹配。设计方面利用了Auto CAD和CATIA等设计软件对试车台架进行了整体设计,并完成对台架的实际校核,确定台架的制作材料及结构的合理性。控制系统通过安装在发动机不同部位的传感器实时地将数据通过CAN总线传输至上位机,数据采集器选择RDAC XF MAP采集模块,数据显示器选择XTREME EMS发动机监测模块进行数据采集、显示及处理工作。编制试车工艺规范,通过大量的试车试验验证了整套设计方案的可行性,并在试验测试过程中对各个系统参数进行了进一步的调试,得出更为合理有效的系统参数和设计方案。
[Abstract]:With the gradual orderly opening of low-altitude areas and the increasing number of private aircraft in China. The general aviation industry ushered in a new development opportunity. The maintenance of piston aeroengine has become a very important work content of the general aviation maintenance enterprise. It is an inevitable trend for aeronautical maintenance enterprises to increase the number of performance testing tasks of general purpose aeroengine. This paper takes the LYCOMING horizontal set full-series engine as the object. A test system suitable for general aviation maintenance enterprises is designed, which can meet the operational parameters test and performance evaluation of multi-model piston general aero-engine. The design process of the whole system is based on meeting the requirements of performance testing in order to reduce the production cost and operate conveniently. The main guiding principle is the short test time. The layout of the test room, the installation of the test bench and the fuel supply system are completed respectively. Various systems such as oil cooling system and control system have carried on reasonable scheme design and parameter matching. In the aspect of design, the overall design of test bench has been carried out by using Auto CAD and CATIA design software. And the actual verification of the bench is completed, and the rationality of the material and structure of the bench is determined. The control system transmits the data to the upper computer through the CAN bus through sensors installed in different parts of the engine in real time. The data collector selects the RDAC XF MAP acquisition module, and the data display selects the XTREME EMS engine monitoring module to collect the data. Display and processing work. Compile test process specifications, through a large number of test tests to verify the feasibility of the entire design, and in the process of testing the system parameters for further debugging. More reasonable and effective system parameters and design scheme are obtained.
