This way, as one rotor's advancing side is the other rotor's retreating side. The rotors may provide asymmetric lift but the combination of the rotors provides symmetric lift, even at higher speeds. The Russian Kamov design bureau has been doing this for decades. The CarterCopter has small wings. It uses the rotor for takeoff and low-speed flight.

Unconventional wind turbines are those that differ significantly from the most common types in use. As of 2012, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.

Rotor Blade Design Introduction. In the section Rotor Aerodynamics we considered the aerodynamic aspects of airfoils. We will, therefore, now look at several rotorblade designs. Airfoil, lift and drag. Probably the single most important rotor design parameter is its Lift/Drag ratio, which should be as high as possible.. This ratio depends on the design of the aerofoil, and before we go on to ...
