Explain lift and drag forces

WebIn fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface.. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag … WebJun 18, 2024 · Lift is what pushes the airplane up, while gravity is the force that pulls the airplane down. Drag is a force that acts against thrust and slows the airplane down. When the thrust is greater than the drag, the …

Reference Area. Notice that the area (A) given in the drag equation is given as a reference area. The drag depends directly on the size of the body. Since we are dealing with aerodynamic forces, the dependence can be characterized by some area.

WebAug 24, 2024 · Recall that the Reynolds number represents the ratio of inertial to viscous forces in the flow. The drag is usually expressed as a coefficient C d = d/(½ρU ∞ 2 D), where d is the drag force per unit span. The flow pattern at high Reynolds numbers (Re D > 10000) is sketched in Figures 1(a) and 1(b). At the leading edge of the cylinder a ... WebThe lift is accompanied by drag which represents the air resistance against the wing as it forces its way through the air. The drag is dependent on the effective area of the wing …

WebThe four forces acting on an aircraft in straight-and-level, unaccelerated flight are thrust, drag, lift, and weight. They are defined as follows: Thrust—the forward force produced by the powerplant/propeller or rotor. It opposes or overcomes the force of drag.
