2007-4-4  Lift and drag vary according to the angle an airfoil makes with its direction of travel through a fluid. This angle is known as angle of attack, angle of incidence, or alpha. In evaluating an airfoil it is common to perform an alpha sweep that records the lift and drag

Lift And Drag - AviationChief.Com

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

Aerodynamic Lift and Drag and the Theory of Flight

2018-11-20  Aerodynamic Lift and Drag and the Theory of Flight . The wings of birds were the original inspiration for the design of aerofoils however it was not until 1799 that engineer George Cayley carried out the first methodical study of the performance of aerofoils. His publication "On Aerial Navigation" in 1810, marked the beginning of the science of Aerodynamics.

Aerodynamic Forces: Definitions of Lift and Drag

2014-10-6  Drag is a loss that must be overcome with another force, if an object is to move against a stream. A force perpendicular to the stream is called lift. A moment around this axis is called a yaw moment. As the the implies, the sign is usually considered positive, when lift pulls upward.
