Single-blade propeller

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. 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. Single bladed propellers are principally used to fulfill engineering requirements that fall outside the scope of efficiency.

gollark: Oh. Hmm. You could probably do with... better fans? New thermal paste?
gollark: You can also muck with process priorities, or CPU frequency scaling, probably.
