In aircraft aerodynamics, the lift-to-drag ratio, or L/D ratio, is the amount of lift generated by an aerofoil, divided by the drag it creates by moving through the air. A higher or more favourable L/D ratio is typically one of the major goals in aircraft design; since a particular aircraft's required lift is set by its weight, delivering that lift with lower drag leads directly to better fuel economy, climb performance, and glide ratio.

Why is maximizing the ratio of lift to drag forces desirable?
Maximizing the lift-to-drag ratio is desirable because it allows an aircraft to generate more lift for a given amount of drag, resulting in improved fuel efficiency and range. A higher lift-to-drag ratio also means the aircraft can fly at higher altitudes and speeds, which can be beneficial for performance and overall aircraft capabilities.
What is the zero lift drag coefficient of Boeing 747?
The zero lift drag coefficient of a Boeing 747 is approximately 0.022. This value represents the drag force experienced by the aircraft when it is not generating lift.
Why drag increases as lift increase - for helis?
As lift increases for helicopters, the angle of attack of the rotor blades must also increase to generate more lift. This higher angle creates more drag due to increased air resistance and turbulence. Additionally, the higher lift forces can lead to increased induced drag, which is generated as a byproduct of producing lift.
What causes induced drag?
Induced drag is caused by the creation of lift on an aircraft's wings. As the aircraft generates lift, it creates vortices at the wingtips, which result in a rearward force component known as induced drag. This drag increases as the angle of attack or lift produced by the wings increases.
What is the importance of the four forces of flight?
The four forces of flight (lift, weight, thrust, and drag) are essential for an aircraft to maneuver and stay airborne. Lift opposes weight and is generated by the wings, while thrust overcomes drag to propel the aircraft forward. Understanding and balancing these forces is critical for safe and efficient flight operations.
Why is maximizing the ratio of lift to drag forces desirable?
Maximizing the lift-to-drag ratio is desirable because it allows an aircraft to generate more lift for a given amount of drag, resulting in improved fuel efficiency and range. A higher lift-to-drag ratio also means the aircraft can fly at higher altitudes and speeds, which can be beneficial for performance and overall aircraft capabilities.
What is the equation for glide ratio?
Lift/Drag x Height loss
Advantages and disadvantages of low wing configuration?
advantage :high lift to drag ratio disadvantage:difficulity in manover
How are the lift and drag components of the wing affected when you lower the flaps?
lift decrease and increase drag
What is the zero lift drag coefficient of Airbus A330-200?
coefficient of drag in 0 lift
What is zero lift coefficient of drag?
For no lift, The induced drag will be zero. However, there will still be drag due to viscous forces and pressure forces.
How does angle of attack affect lift and drag?
A higher angle of attack has an increase of both lift and drag.
What is the zero lift drag coefficient of Boeing 747?
The zero lift drag coefficient of a Boeing 747 is approximately 0.022. This value represents the drag force experienced by the aircraft when it is not generating lift.
What is the dfference between lift and drag?
drag you pull across the ground lift you pick up and take around
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
Do planes fall out of the sky if they have no engine power?
Aeroplanes can often glide to safety after loss of engine power. All aerplanes have a lift/drag ratio and this determines how far they can travel with no power before landing. If the lift/drag ration is 10:1 (for example) then the aeroplane can travel 1000 feet horizonatally for every 100 feet that is lost vertically. Weather conditions, weight and aircraft configuration can all affect the lift/drag ratio so if you do lose engine power, don't hang abuot before finding a suitable place to land!
