Table 1. The sensitivity of each parameter to the dimensionless heat flux density around a hypersonic aircraft

Parameter	Influence on heat flux density	Degree of sensitivity
Static pressure	Little influence
Static temperature	Medium influence, positively correlated
Mach number	Small influence, positively correlated
Flight altitude	Medium influence, negatively correlated
Angle of attack	Large influence, positively correlated
Model scale	Little influence
Wall temperature	Small influence, negatively correlated
