This chapter explores airfoil aerodynamics in rarefied environments, presenting a semi-analytical method for assessing lift and drag in free-molecular flow. Parametric studies investigate the influence of rarefaction on aerodynamic performance, considering variables such as Mach number, Reynolds number, angle of attack, camber, and airfoil thickness.

摘要

This chapter explores airfoil aerodynamics in rarefied environments, presenting a semi-analytical method for assessing lift and drag in free-molecular flow. Parametric studies investigate the influence of rarefaction on aerodynamic performance, considering variables such as Mach number, Reynolds number, angle of attack, camber, and airfoil thickness.
