[DOC] [TLE] Airfoil - Wikipedia [PAR] An airfoil (in American English) or aerofoil (in British English) is the shape of a 
wing, blade or ... Subsonic flight airfoils have a characteristic shape with a 
rounded leading ... the airfoil deflects the oncoming air (for fixed-wing aircraft, a 
downward force), ... The lift force can be related directly to the average top/bottom 
velocity... [DOC] [TLE] Lift (force) - Wikipedia [PAR] 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 with 
the drag force, which is the component of the surface force parallel to the flow 
direction. If the fluid is air, the force is called an aerodynamic force. .... For
