摘要
无人机系统在局部冲突战争中逐渐取得了尖兵地位,各系统的可靠性对于无人机实现战役战术任务十分重要。双发无人机不仅提升了动力系统余度,也为研究发动机的空中起动特性提供了平台。以某双发无人机为研究对象,建立无人机双发停车时的空滑模型,通过空滑性能分析确定空滑返场最远点,即惯性起动试验状态点位置,完成了任务航线和试飞流程的规划,进行地面惯性起动试验和模拟单发飞行和着陆试验后,成功完成2个状态点的空中惯性起动试验。结果表明,目标无人机配装的发动机具有良好的空中惯性起动性能,惯性起动可靠性较高,惯性起动试飞技术具有较好的工程应用价值。
UAVS have gradually become super stars in local conflict and wars,and the reliability of each system is very important for UAVs to achieve operational tactical tasks.The dual-engine improved the margin of the power system,but also provided a platform for studying spooldown airstart of the UAV engine.An forced landing model was constructed to analysis the performance,determine the location of the test position,completed the planning of the mission route and process of flight test,and conducted the ground spooldown airstart test and simulated single-engine flight and landing test.Successfully completed spooldown airstart test at two position.The result shows that the engine equipped with the target UAV has good performance of spooldown airstart,the test technology has good engineering application value.
