Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed , and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit.
Engine and propeller production was at plants in New Jersey, Pennsylvania, and Ohio. In May 1942, the U.S. government assigned Curtiss-Wright a defense production factory for wartime aircraft construction at Louisville, Kentucky , to produce C-76 Caravan cargo aircraft, which was constructed mostly of wood, a non-priority war material.
Powerfin produces carbon fiber two, three, four and five-bladed propellers for two-stroke and four-stroke engines up to the Rotax 914 of 115 hp (86 kW). [2] [4] [5] [6]The company is noted for its use of the Clark Y airfoil, infinite blade angle adjustment, as well as for the very low rotating inertia of its designs, a key wear factor on lightweight engine gearboxes.
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.
The 1954 citation by the Secretary of the US Air Force for Ernest G. McCauley reads: "His invention of the HYDRO-CONTROLLABLE PROPELLER in 1924 has been an outstanding achievement, and culmination with his more recent inventions of the SOLID STEEL Propeller for trainers in 1939, and the one-piece MET-L-PROP for the light airplane in 1947: All ...

The Grob G 110 was a single-engined two-seat light aircraft, made mainly of glassfibre, that was designed and built by the German manufacturer Grob Aircraft in the early 1980s. Two prototypes were built, with the first example making its maiden flight on 6 February 1982, but development was abandoned after the first prototype crashed later that ...
