Lift and Drag

Lift and drag forces acting on a body like an air foil in a fluid flow.

Lift and Drag Calculator

Calculate the lifting force, drag force, and required thrust power for a body in fluid flow using the following formulas:

Lifting Force: FL = cL × ½ × ρ × v² × A

Drag Force: FD = cD × ½ × ρ × v² × A

Required Thrust Power: P = FD × v

Where:

  • FL = lifting force (N)
  • FD = drag force (N)
  • cL = lifting coefficient
  • cD = drag coefficient
  • ρ = density of fluid (kg/m³)
  • v = flow velocity (m/s)
  • A = body area (m²)
  • P = power (W)
