lift force

lift force

A fluid flowing past the surface of a body exerts a force on it. Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts . The lift force, lifting force or simply lift is the sum of all the forces on a body that force it to move . The most common type of lift is that of a wing of an aircraft. Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift . Lift depends on the density of the air, the square of the velocity, the air's viscosity . Wright' discussing the lift force and how it affected the flight of their aircraft. The result of the movement of the wing through stationary air is a lift force perpendicular to the motion of the wing, which is greater than the downwards . 名詞解釋: 當氣流流經物體或飛具時,由於氣流的作用,在物體上產生一作用力及力矩。這作用力可分解成平行於氣流方向的阻力(drag force),和垂直於氣流方向的 . 2007年4月4日 - These incredible feats are all due to the lift force generated by airfoils moving through air. Of course nothing comes for free; for lift, the cost is . Heavier-than-air flight is made possible by a careful balance of four physical forces: lift, drag, weight, and thrust. For flight, an aircraft's lift must balance its weight, .
