The induced angle of attack (αi​) for an elliptic lift distribution is derived based on the lift distribution of an elliptically loaded wing. The elliptic lift distribution is a theoretical idealization commonly used in aerodynamics for its desirable characteristics. It’s a distribution where the lift generated by each spanwise station is proportional to the local […]

Induced drag per unit span refers to the amount of induced drag generated by an airfoil section located at an arbitrary spanwise station, normalized by the wing’s span.

Lift per unit span at an arbitrary spanwise station, often denoted as L′(y0​), refers to the lift generated by an airfoil section located at that specific spanwise position, normalized by the wing’s span.

The effective angle of attack is an important concept in aerodynamics that takes into account the combined effects of the actual angle of attack and the downwash induced by neighboring flow features, such as wingtip vortices or other airfoil sections. In a simplified explanation, the effective angle of attack represents the angle at which the
