The meaning of AIRFOIL is a body (such as an airplane wing or propeller blade) designed to provide a desired reaction force when in motion relative to the surrounding air.

Airfoils are highly-efficient lifting shapes, able to generate more lift than similarly sized flat plates of the same area, and able to generate lift with significantly less drag. Airfoils are used in the design of aircraft, propellers, rotor blades, wind turbines and other applications of …

2021年7月20日 · The definition of an airfoil (or aerofoil in the UK) is a structure with curved surfaces, such as an airplane wing, fins, and horizontal stabilizer, designed to provide the best ratio of lift to drag during flight.

2022年3月14日 · An airfoil (or aerofoil in British English) is any structure designed to manipulate the flow of a fluid to produce a reaction, which in an aircraft’s case, is aerodynamic lift. The wings of fixed-wing aircraft feature airfoil-shaped cross-sections.

2023年5月29日 · Airfoil is a shape used for airplane wings that consists of a curved top and a flat bottom. It’s designed to increase lift production by changing the speed at which air moves over the wings. Air will move faster over the top section, and it will more slower under the bottom section.

Airfoil, shaped surface, such as an airplane wing, tail, or propeller blade, that produces lift and drag when moved through the air. An airfoil produces a lifting force that acts at right angles to the airstream and a dragging force that acts in the same direction as the airstream.

The airfoil is designed to accelerate airflow over its upper surface, decreasing pressure above the wing. Simultaneously, the airflow is slower beneath the curved or flat bottom surface, maintaining higher pressure. This disparity in pressure across the airfoil creates an upward lift force.

airfoil - a device that provides reactive force when in motion relative to the surrounding air; can lift or control a plane in flight

An airfoil is a flat shape such as a wing that is intended to produce a particular effect from the flow of air.

any surface, as a wing, aileron, or stabilizer, designed to aid in lifting or controlling an aircraft by making use of the air currents through which it moves.
