Hamilton Standard was an American aircraft propeller parts supplier. It was formed in 1929 when United Aircraft and Transport Corporation consolidated Hamilton Aero Manufacturing and Standard Steel Propeller into the Hamilton Standard Propeller Corporation.
A Hamilton Standard variable-pitch propeller on a 1943 model Stinson V77 Reliant. A number of early aviation pioneers, including A. V. Roe and Louis Breguet, used propellers which could be adjusted while the aircraft was on the ground. [3]
UTC Aerospace Systems (UTAS) was one of the world’s largest suppliers of aerospace and defense products, headquartered in Charlotte, North Carolina, United States.The company was formed in August 2012 when parent United Technologies Corporation merged their existing subsidiary Hamilton Sundstrand with the newly-acquired Goodrich Corporation.
Thomas Foster Hamilton (July 28, 1894 – August 12, 1969) was a pioneering aviator and the founder of the Hamilton Standard Company. [1]Since 1930, Hamilton Standard (now Hamilton Sundstrand) was involved with revolutionizing the propulsion technology of propeller-driven aircraft, prior to World War II.
A Dallas-built version of the P-51D, designated the P-51K, was equipped with an 11 ft (3.4 m) diameter Aeroproducts propeller in place of the 11.2 ft (3.4 m) Hamilton Standard propeller. [44] The hollow-bladed Aeroproducts propeller was unreliable, due to manufacturing problems, with dangerous vibrations at full throttle and was eventually ...
The BT-13 had a more powerful engine and was faster and heavier than the primary trainer. It required the student pilot to use two way radio communications with the ground and to operate landing flaps and a two-position Hamilton Standard controllable-pitch propeller (or, more commonly, a constant-speed propeller [1]).
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.
In 1929, Caldwell transitioned from the US Army Air Service to the Hamilton Standard Propeller Corporation where he further developed the controllable-pitch propeller. The controllable-pitch or variable-pitch propeller tied together the major aeronautical advances of aerodynamic drag reduction and increased engine power.
