飞行及气象参数对LHTC的影响

The Effect of Flight and Meteorological Parameters on the LHTC

以NACA0012翼型和某型飞机翼型为研究对象,采用边界层积分法计算了翼型表面的局部对流换热系数(Local Heat Transfer Coefficient),研究了飞行迎角、来流马赫数、来流静温、MVD、LWC对LHTC的影响。研究发现,随着各项参数的变化,LHTC的变化具有一定规律,无法拟合出合理的曲线表征各参数对LHTC的影响,曲线簇表征各参数对LHTC的影响缺乏翼型通用性。

To NACA0012 airfoil and certain airplane wing as the research object, the integral boundary layer method is applied to calculate the Local Heat Transfer Coefficient （LHTC） of the airfoil surface. This paper has studied the effect of the flight Angle of attack, Mach number, static temperature, MVD, LWC on the LHTC. The study shows that as the change of the parameters, the change of the LHTC has certain law, but it can＇t fitting out reasonable curve to characterize the influence of various parameters to LHTC, and curve family characterized the effect of parameters on LHTC is lack of airfoil generality.
