It is an excellent approximation for the conceptual design of slender bodies in which the shock wave is in the vicinity of the surface of the body.
It is a scalar potential used in the potential flow theory It is used in continuum mechanics when a continuum occupies a simply connected region and is irrotational
The downward vertical angle between the horizontal and the velocity (relative to the wing of an aircraft) of the airstream passing over the wing
The lift curve slope is a measure of how rapidly the wing generates lift with a change in AOA
The lift curve slope is a measure of how rapidly the wing generates lift with a change in AOA for Compressible flow
