Compressibility Correction to Kutta-Joukowski and Maskell's formulae using vortex-force theory

In this theoretical work, the existing links between the vortex-force theory, Kutta-Joukowski lift theorem and Maskell's lift-induced drag formula is emphasized. A compressibility correction is identified and it is proven that it gradually vanishes in the far wake. This theoretical equivalence...

Zusammenfassung:In this theoretical work, the existing links between the vortex-force theory, Kutta-Joukowski lift theorem and Maskell's lift-induced drag formula is emphasized. A compressibility correction is identified and it is proven that it gradually vanishes in the far wake. This theoretical equivalence is further tested on subsonic and transonic RANS computations around the M6 wing.
