Calculate lift from pressure distribution
WebTo describe the distribution of pressure over a body, every point on the body is given a unique pressure coefficient, 𝐶 . Lift & drag are two aerodynamic forces that affect how … Weba function of the surface slope distribution, dz/dx. In particular, the expressions for the local pressure difference and integrated lift and moment about the leading edge are: (Note that the expression relating C and applies only to thin airfoils. ) This method of computing the circulation distribution permits us to compute the pressure across the
