Calculate Lift Force







Formula

The formula to calculate the Lift Force is:

\[ F_l = C_l \cdot A \cdot \frac{d \cdot V^2}{2} \]

What is Lift Force?

A lift force is a force that is exerted on an object that is moving through a fluid. As the object moves through the fluid, two components of force arise. One of these is parallel and opposite to the flow of the object, known as a drag force. This force slows the object down. The other component of force is perpendicular to the flow of the object, known as the lift force. The lift force is generated as a result of the object creating a difference in airspeed along opposite sides of the object. This difference in airspeed creates a pressure differential, and thus a force, as the air tries to equalize its pressure.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Lift Force:

\[ F_l = 1.2 \cdot 20 \cdot \frac{1.225 \cdot 50^2}{2} = 1.2 \cdot 20 \cdot \frac{1.225 \cdot 2500}{2} = 1.2 \cdot 20 \cdot 1531.25 = 36,750 \text{ N} \]

The Lift Force is 36,750 N.
