基于无人机使用的航空发动机自动加速性试飞方法试验

Flight Test of Automatic Acceleration with UAV Aero Engine Based on UAV

根据无人机用发动机设计和使用特点,针对发动机加速性试飞考核项目,分析有人机和无人机加速试飞动作过程,提取试飞核心要素,制定具体方案设计流程,并通过试飞验证。结果表明,该试飞方法在无人机使用范围内满足航空发动机加速性试飞考核要求,方法具有一定的通用性,可以指导后续发动机加速性试飞。

As a key validation item,the aero engine′s thrust acceleration transient is investigated in this paper based on UAV design.According to the characteristics of design and use of UAV engine,the differences of thrust acceleration transient between manned aircraft and unmanned aircraft are analyzed;the key elements of the acceleration process are extracted;the specific design process is formulated and verified through flight test.The results show that the test method can meet the requirements of aero-engine acceleration test within the scope of UAV use;furthermore,this method has certain generality and can guide the subsequent engine acceleration tests.
