Coefficient lift formula

WebEvery airfoil has a lift curve and drag curve where the lift and drag coefficients are plotted against the angle of attack. The lift and drag curves offer useful information such as the stall angle and zero lift angle. The stall angle is the angle of attack where the airfoil reaches a maximum lift coefficient and begins to decrease.

In fluid dynamics, the lift coefficient (CL) is a dimensionless quantity that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area. A lifting body is a foil or a complete foil-bearing body such as a fixed-wing aircraft. CL is a function of the angle of the body to the flow, its Reynolds number and its Mach number. The section lift coefficient cl refers to the dynamic lift characteristics of a two-dimensional foil section, with the re…

WebOct 24, 2007 · I think I read somewhere that a very approximate value for the lift coefficient of a flat plate is L=1.05*sin (2*a) where a is the angle of attack (I have to say again that this is just a ballpark figure). Also, the lift-coefficient can be determined analytically for some very simple wing-shapes. popular toys in 1950WebAs mentioned, the drag equation with a constant drag coefficient gives the force experienced by an object moving through a fluid at relatively large velocity (i.e. high Reynolds number, Re > ~1000). This is also called quadratic drag.
