Induced drag

Induced Drag Explained:

Induced drag is an aerodynamic phenomenon that occurs when an airfoil produces lift. As the airfoil generates lift, it also creates a backward force that opposes the direction of motion, known as drag. This type of drag is called induced drag, and it is an inevitable byproduct of producing lift.

The amount of induced drag varies inversely with airspeed. As the airspeed decreases, the angle of attack must increase to maintain lift, which in turn increases induced drag. Conversely, as airspeed increases, induced drag decreases.

Induced drag is caused by the same factors that produce lift, such as the shape and size of the airfoil, and the angle of attack. However, it can be reduced by using certain techniques such as winglets, which help to reduce the vortices that cause induced drag.

Induced drag is an important consideration for aircraft designers and pilots, as it affects the overall performance and efficiency of an aircraft. Understanding induced drag and its relationship to airspeed is crucial for achieving optimal performance during flight.
