Wing’s Angle of Attack (): The angle of attack is the angle between an imaginary line (the chord line) that connects the wing’s leading edge to its trailing edge and the direction of the oncoming airflow relative to the wing. It is typically measured in degrees or radians.
- represents the wing’s angle of attack, which is the angle between the chord line of the wing and the oncoming airflow. It’s a critical parameter that affects lift and aerodynamic performance.
- is the lift coefficient of the wing, which quantifies the lift being produced by the wing at a specific angle of attack (). It’s a dimensionless aerodynamic parameter.
- is the lift curve slope of the wing. It measures how the lift coefficient () changes with changes in the angle of attack (). It’s often expressed in radians per radian.
- represents the zero-lift angle of attack of the wing. This is the angle of attack at which the wing experiences zero lift, or in other words, it’s the angle at which the wing is in a symmetric, non-lifting condition.
