WebMay 1, 2024 · Failure to rotate. Rotation is also essential to exhaust valve survival. Most Continentals and Lycomings employ exhaust valve rotators—Lycoming calls them “rotator caps” and Continental calls them “rotocoils”—that cause the valve to rotate a fraction of a degree each time the valve opens. At typical cruise rpm, the valve typically ... WebMar 29, 2024 · For a = 12°, 1 - Sin (12°) = 0.792 = 79.2 % of the unloaded speed. Welcome to PF. The unloaded speed will be when the angle of attack of the blade airfoil is close to zero. As power is extracted from the rotor, the angle of attack will increase to between about 5° and 15°, and the rotor will slow down.
