摘要
战斗机广泛地使用燃油作为飞机发热部件的热沉,先进战斗机在综合热管理技术的发展基础上,更加充分有效地利用燃油来冷却.用热量平衡方法建立了燃油传热关系数学模型,分析了超声速巡航状态下油箱中的燃油温度随时间的变化.结果表明:战斗机在超声速飞行状况下,影响燃油温度的最主要因素是飞行马赫数和燃油的回流量.应用C软件通过计算仿真来求解油箱内燃油温度.
Fuel is widely used as a heat sink for heat components of fighter aircraft. With the development of the integrated thermal management technology, fuel is utilized more efficiently to cool off especially for advanced fighter aircraft. Heat balance method has been used to build heat transfer mathematics modeling, and the time-dependent fuel temperature changes during supersonic cruise were analyzed in this paper. The results show that, the recirculation of the fuel and the flight Mach number are major influential factors to the fuel temperature during supersonic cruise. The computation and simulation of the temperature of fuel irt the fuel tank was carried out by using the program based on C software.
