The moment about the leading edge () refers to the torque or twisting effect applied to an object or surface, typically an airfoil or wing, around its leading edge due to aerodynamic forces. In aerodynamics, moments play a crucial role in determining the balance and stability of an aircraft or other objects moving through a fluid medium.
- is the moment about the leading edge.
- is the dynamic pressure of the freestream flow.
- is the chord length of the airfoil (the distance from leading edge to trailing edge).
- is the angle of attack, which is the angle between the airfoil’s chord line and the oncoming airflow.
