燃油箱热参数是飞机燃油箱可燃性定量分析的关键输入参数之一。依据燃油箱热量平衡方程,推导得出了燃油箱两个热参数平衡温差与热时间常数的定量关系式。基于该关系式,给出了燃油箱热参数的计算方法。此外,还介绍了燃油平均温度的两种获取方法:燃油箱热模型方法和燃油系统热特性飞行试验方法。
Fuel tank thermal parameters are one of the key input parameters for the quantitative analysis of flammability of aircraft fuel tanks. According to the fuel tank heat balance equation, the quantitative relation between the equilibrium temperature difference and the thermal time constant of two thermal parameters of the fuel tank is deduced. Based on the relationship, the calculation method of the thermal parameters of the fuel tank is given. In addition, two methods to obtain the average fuel temperature are introduced: the fuel tank thermal model method and the fuel system thermal characteristic flight test method.
