What is drag and lift in aerodynamics?

Lift is defined as the component of the aerodynamic force that is perpendicular to the flow direction, and drag is the component that is parallel to the flow direction.

Why are lift and drag called aerodynamic forces?

Lift and drag are considered aerodynamic forces because they exist due to the movement of an object (such as a plane) through the air. The weight pulls down on the plane opposing the lift created by air flowing over the wing. Thrust is generated by the propeller (engine) and opposes drag caused by air resistance.

When discussing lift the most important factor as to how much lift a wing can produce is related to?

Generally speaking, there are really only two ways a pilot can control the amount of lift the wings can generate: airspeed and angle of attack. The faster the airplane travels, the more lift the wings will generate. Similarly, the higher the airplane’s angle of attack, the more lift the wings will generate.

Does drag increase as lift increases?

Lift/Drag Ratio Both lift and drag increase as you increase the angle of attack of an airfoil, to a point. Beyond that point drag continues to increase, but lift decreases.

Does drag increase with lift?

Lift/Drag Ratio Both lift and drag increase as you increase the angle of attack of an airfoil, to a point. Beyond that point drag continues to increase, but lift decreases. The best lift/drag ratio occurs at the angle of attack that gives the most lift for the least drag – usually about 18 degrees angle of attack.

Why does lift induced drag decrease with speed?

Induced drag increases as the angle of attack of a wing increases. Induced drag therefore increases as airspeed decreases, as the angle of attack must increase to maintain the lift required for level flight. Parasite drag has little effect at low speeds, however it increases as airspeed increases.
