The Lift-to-Drag ratio is a measure of the efficiency of an aircraft in generating lift compared to the amount of drag it produces. A higher ratio indicates a more efficient aircraft, as it means that the aircraft is producing a greater amount of lift relative to the drag it is experiencing. This ratio is often used to assess the performance and efficiency of an aircraft. The formula for Lift-to-Drag ratio is:
where:
- is the lift force,
- is the drag force,
- is the coefficient of lift,
- is the coefficient of drag.
