S1223翼型俯仰-沉浮运动的非定常气动特性分析
Generally, the aerodynamic performance of airfoil for the application of the propeller of low-dynamic aircrafts in Near Space is mainly effected by Reynolds number, Mach number, the angle of attack, the airfoil chord length b and the airfoil relative thickness C{top}-=c/b, namely f (Re, ...
