Single-blade propeller

From Wikipedia, the free encyclopedia

A single-blade propeller may be used on aircraft to generate thrust. Normally propellers are multiblades but the simplicity of a single-blade propeller fits well on motorized gliders, because it permits the design of a smaller aperture of the glider fuselage for retraction of the powerplant. The counterbalanced teetering mono-blade propeller generates fewer vibrations than conventional multiblade configurations.[citation needed] Often, single blade propeller configurations are touted as having a much greater efficiency than multiblade propellers, but this is a falsehood outside the inertial losses in spinning a heavier propeller, and the minimal additional drag from added blades.[citation needed] Single bladed propellers are principally used to fulfill engineering requirements that fall outside the scope of efficiency.
