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...

change of lift and drag with angle of attack (AoA) are called respectively the lift and drag coefficients CL and CD. The varying ratio of lift to drag with...

chord line but use the zero lift axis where, by definition, zero angle of attack corresponds to zero coefficient of lift. Some British authors have used...

wing's area projected in the lift direction. In calculations it is convenient to quantify lift in terms of a lift coefficient based on these factors. No...

form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. The drag coefficient of a complete structure...

aerodynamics, the zero-lift drag coefficient C D , 0 {\displaystyle C_{D,0}} is a dimensionless parameter which relates an aircraft's zero-lift drag force to its...

the theoretical optimal lift coefficient at ideal angle of attack CLI = 0.15 L (this is not the same as the lift coefficient CL), P: a single digit for...

lift coefficient versus angle of attack line is 2 π {\displaystyle 2\pi \!} units per radian. As a consequence of (3), the section lift coefficient of...
