Lift Force Calculator
Calculate aerodynamic lift force using the lift equation with precise unit conversions
Lift Force Formula
Where:
- FL = Lift Force (N)
- CL = Lift Coefficient (dimensionless)
- A = Wing Area (m²)
- ρ = Air Density (kg/m³)
- V = Velocity (m/s)
Example Calculations
Commercial Aircraft Example
Given: CL = 1.2, Wing Area = 150 m², Air Density = 1.225 kg/m³, Velocity = 80 m/s
Solution: FL = 1.2 × 150 × 1.225 × 80² / 2 = 882,000 N
Small Aircraft Example
Given: CL = 0.8, Wing Area = 12 m², Air Density = 1.225 kg/m³, Velocity = 45 m/s
Solution: FL = 0.8 × 12 × 1.225 × 45² / 2 = 11,907 N
What is Lift Force?
Lift force is the component of aerodynamic force perpendicular to the direction of motion. It’s generated when air flows over and under a wing at different speeds, creating a pressure difference that results in an upward force.
Lift Coefficient (CL)
The lift coefficient is a dimensionless number that describes the relationship between the lift generated by a lifting body and the fluid density, velocity, and area. It varies with angle of attack and wing design.
Factors Affecting Lift
Lift force depends on wing area, air density, velocity squared, and the lift coefficient. Higher velocities dramatically increase lift due to the squared relationship in the equation.
Applications
This calculator is used in aircraft design, aerodynamics research, drone development, and educational purposes to understand the principles of flight and optimize wing designs.
