摘要

摘要: 发动机工况调节范围对无人机的安全运行具有重要影响.通过对增压活塞发动机与飞机的动力学分析,得到了使用升限上最大爬升率对螺旋桨和发动机的动力要求,提出了使用升限上发动机可调范围与剩余功率的要求.对增压器匹配提出了新的要求,即使用升限范围内保证飞机巡航工况能够恢复海平面功率.通过某发动机的仿真分析,确定了其使用升限高度的可调工况范围,理论分析了增压器参数对可调范围的影响,给出了匹配原理与建议.该过程也可用来校验使用升限高度下安全性可调裕度,有助于安全操控.

Abstract: A wide operating range of engine is of vital to the safety operation of aircraft, especially at service ceiling. Through the dynamic analysis of the matching process between the aircraft and power plant which is composed of the turbocharged reciprocating engine and propeller, quantitative performance requirement for engine from the service ceiling was proposed, which proved to associate with the operating range and surplus power of engine. The operating range can also be used to evaluate the matching result besides the design point performance. This means that the conditions of cruising should guarantee the engine power recovery to sea level. A calibrated simulation model was created by GT-power. Its operating range was obtained by simulation and the factors influencing operating range were analyzed in theory. The advice of matching turbochargers based on the wide operating range was given considering the safety. This process can also be used to verify the margin of adjustment at service ceiling to ensure the safety.
