A 6-bladed Hamilton Standard 568F propeller on an ATR 72 short-haul airliner. Lowry [27] quotes a propeller efficiency of about 73.5% at cruise for a Cessna 172.This is derived from his "Bootstrap approach" for analyzing the performance of light general aviation aircraft using fixed pitch or constant speed propellers.

Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
Throughout the mid-20th century, Sensenich wood props were available on nearly all 1-seat and 2-seat U.S.-made aircraft, many of which still operate today. Sensenich expanded into airboat propellers in 1949, establishing a second factory for that market at Plant City, Florida under the name Sensenich Wood Propeller Company.
McCauley Propeller Systems is an American aircraft propeller manufacturer, founded in Dayton, Ohio in 1938 by Ernest G. McCauley. [1] At its peak, it was reportedly the world's largest aircraft propeller manufacturer, [ 2 ] or at least the largest manufacturer of general aviation propellers.
It was made to be turned by the hand or foot." [12] The brass propeller, like all the brass and moving parts on Turtle, was crafted by Issac Doolittle of New Haven. [13] In 1785, Joseph Bramah of England proposed a propeller solution of a rod going through the underwater aft of a boat attached to a bladed propeller, though he never built it. [14]
de Havilland Propellers was established in 1935, as a division of the de Havilland Aircraft company when that company acquired a licence from the Hamilton Standard company of America for the manufacture of variable-pitch propellers at a cost of about £20,000. [1] [citation needed] Licence negotiations were completed in June 1934.
Single-blade propeller drawing Single-blade propeller and glider drawing. 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.
