X. and Tung, C., ‘Experimental and analytical studies of a model ... description of the induced velocity distribution is not necessary,and much useful work can be done by treating the rotor as a lifting surface with aninfinite number of blades. The dynamics ... and an increase of induced velocitytowards the trailing edge. Accordingly, Glauert proposed a second formula:vi = vi0(1 + Kx cos ψ) (3.4)where vi is the general induced velocity and...
