Apply the measurements of the tip and root of the wing to the formula: taper ratio = C tip / C root. Use as an example a plane with a wing root measurement of 20 feet, or 240 inches, and a wing tip measurement of 6 feet, or 72 inches. The formula then becomes: 72/240 = 0.3...
The forces of cycloidal rotors increase with taper ratio. The blades with smaller taper ratio have slightly larger aspect ratio. Therefore according to the wing theory, it is expected that the cycloidal rotors with taper ratio near 0.4 and 0.5 would be more efficient.33 However in Fig. 6, ...
