lift-to-drag ratio

The lift-to-drag ratio is a measure used in aviation and aerodynamics to evaluate the efficiency of an aircraft or other flying object. It compares the amount of lift generated (the upward force that allows flight) to the drag (the resistance it faces while moving through the air). A higher lift-to-drag ratio indicates that the aircraft can produce more lift with less drag, making it more efficient in flight. This ratio is crucial for optimizing fuel consumption, range, and overall performance, helping pilots and engineers design better, more capable aircraft.
