Lift Coefficient

Non-dimensional lift, obtained by rearranging the lift equation.

Formula

CL=2Lρv2SC_L = \dfrac{2L}{\rho v^2 S}

Variables

C_LLift coefficient
LLift
\rhoDensity
vSpeed
SWing area

Example

Deploying flaps raises the lift coefficient, letting an aircraft fly slower on approach.

Did You Know?

The lift coefficient captures a wing's shape and angle in a single dimensionless number.
