整理了风斗进入短舱的冷气流量的变化规律,对发动机通风冷却系统各影响因素进行分析,分析了发动机状态、飞行状态(高度、马赫数)对飞机短舱内温度变化的影响规律。结果表明,发动机状态是影响发动机通风冷却系统的主要因素,飞行状态对涡喷和涡扇发动机通风冷却系统的影响规律不同。
The rules of the air flow in the nacelle were sorted out. The influencing factors of the ventilation system of the engine were analyzed. The influence of the engine state and the flight state (altitude and Mach number) on the temperature change in the nacelle was analyzed. The results show that the engine condition is the main factor affecting the ventilation system of the engine. The influence of the flight condition on the ventilation and cooling system of the turbofan and turbofan engines is different.
