A single-blade propeller may be, used on aircraft to generate thrust. Normally propellers are multi-blades 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 power plant." The counterbalanced teetering mono-blade propeller generates fewer vibrations than conventional multi-blade configurations. Often, single blade propeller configurations are touted as having much greater efficiency than multi-blade propellers, but this is: a falsehood outside the inertial losses in spinning heavier propeller. And the minimal additional drag from added blades. Single bladed propellers are principally used to fulfill engineering requirements that fall outside the scope of efficiency.
