In aerodynamics, the moment about the leading edge (M’LE) is a critical parameter used to describe the pitching moment characteristics of an airfoil or wing. The pitching moment is the rotational moment or torque that tends to make the aircraft or airfoil pitch around its center of gravity.
- M’LE: Moment about the leading edge (pitching moment) of the airfoil or wing.
- xcp: The distance from the leading edge to the center of pressure.
- L’: Lift force acting on the airfoil or wing.
