The Kutta–Joukowski theorem is a fundamental theorem in aerodynamics used for the calculation of lift of an airfoil (and any two-dimensional body including circular cylinders) translating in a uniform fluid at a constant speed large enough so that the flow seen in the body-fixed frame is steady and unseparated. The theorem relates the lift generated by an airfoil to the speed of the airfoil through the fluid, the density of the fluid and the circulation around the airfoil. The circulation is defined as …

For a flat span, e must be smaller or equal to 1, and it's only equal to 1 when the lifting surface has an elliptical lift distribution. When the wing has zero twist, an elliptical planform produces an elliptical lift distribution. blackwing engine specsWeblift is zero, or aL=0= 0° If the camber line lies above the chord line, then an asymmetrical airfoil section results. (Upper surface is not a mirror image of the lower surface.) When the free-stream velocity is alined along the chord line (a = 0°), a positive lift results. The chord line must be negatively inclined with respect to the free blackwing engine infoWebbut since the coefficient of lift is a function of angle of attack: Cl=Clα(α∞+αgeo−α0−αi)(3){\displaystyle C_{l}=C_{l_{\alpha }}(\alpha _{\infty }+\alpha _{geo}-\alpha _{0}-\alpha _{i})\qquad (3)} hence the vortex strength at any particular spanwise station can be given by the equations: black winged stilt potteric carr
