Sylvanus Albert Reed
Sylvanus Albert Reed (8 April 1854 – 1 October 1935) was an American aerospace engineer who developed the modern metal aircraft propeller. Early life and career Reed Graduated from Columbia University in 1874. He worked as an engineer specializing in electrical signals for railroad safety until retirement in 1912. Later career In 1915 Reed experimented with metal propellers using a 10 hp electric engine driving propellers up to 19,000 rpm. He researched propeller shapes and materials that could withstand tip speed up to Mach 1.35. In 1920 he was encouraged by the local police to move his experiments from his attic and rented a shop at the Curtiss aircraft company's Garden City factory. He invented the Reed Metal Propeller, testing it in August 1921 on a Curtiss K-6 powered Standard. It was developed for use on the PW-8 and Curtiss D-12 powered Hawk. He won the 1925 Collier Trophy for his development of the Reed Aeronautic Propeller. In December 1934 Reed donated an endo ...

Albany ( ) is the capital of the U.S. state of New York, also the seat and largest city of Albany County. Albany is on the west bank of the Hudson River, about south of its confluence with the Mohawk River, and about north of New York City. The city is known for its architecture, commerce, culture, institutions of higher education, and rich history. It is the economic and cultural core of the Capital District of the State of New York, which comprises the Albany–Schenectady–Troy Metropolitan Statistical Area, including the nearby cities and suburbs of Troy, Schenectady, and Saratoga Springs. With an estimated population of 1.1 million in 2013, the Capital District is the third most populous metropolitan region in the state. As of 2020, Albany's population was 99,224. The Hudson River area was originally inhabited by Algonquian-speaking Mohican (Mahican), who called it ''Pempotowwuthut-Muhhcanneuw''. The area was settled by Dutch colonists who, in 1614, built Fort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caroline Gallup Reed
Caroline Gallup Reed (also known as Mrs. Sylvanus Reed; 5 August 1821 in Berne, New York – 17 November 1914 in New York City) was a United States educator. Biography She was the daughter of Albert Gallup, treasurer of Albany County, New York, and was educated at St. Peter's School and the female academy in Albany. In 1851 she married Sylvanus Reed, and in 1864 established a school for young women in New York City.

Propeller (aircraft)
An aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the Tupolev Tu-95, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia University
Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States.

Curtiss P-1 Hawk
The P-1 Hawk (Curtiss Model 34) was a 1920s open-cockpit biplane fighter aircraft of the United States Army Air Corps. An earlier variant of the same aircraft had been designated PW-8 prior to 1925."US Military Aircraft Designations & Serials 1909-1979 by J.M. Andrade, (Midland Counties Publications, ) 1970, 252pp. Design and development PW-8 The Curtiss P-1 Hawk was the first US Army Air Service aircraft to be assigned the "P" (Pursuit) designation which replaced seven designations for pursuit aircraft, including "PW" (for "Pursuit, Water-cooled engine"). The P-1 was the production version of the Curtiss XPW-8B, an improved variant of the PW-8, 25 of which were operational with the Air Service's 17th Pursuit Squadron In September 1923, the Army ordered production of the PW-8.

Curtiss D-12
The Curtiss D-12, sometimes identified with the military designation Curtiss V-1150, was an aircraft engine of 18.8 liter displacement. It was a water-cooled V12, producing 443 hp (330 kW) and weighing 693 lb (314 kg). It was designed by Arthur Nutt in 1921 and used in the Curtiss CR-3 for the 1923 Schneider Trophy race. Fairey Aviation of England imported 50 Curtiss-built examples in 1926, renaming them the Fairey Felix. The D-12 was one of the first truly successful aluminum cast-block engines and was extremely influential in the interwar period.

Collier Trophy
The Robert J. Collier Trophy is an annual aviation award administered by the U.S. National Aeronautic Association (NAA), presented to those who have made "the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year." Robert J. Collier, publisher of ''Collier's Weekly'' magazine, was an air sports pioneer and president of the Aero Club of America. In 1910, he commissioned Baltimore sculptor Ernest Wise Keyser to make the ''Aero Club of America Trophy''. First awarded in 1911 to Glenn H. Curtiss for his successful development of the hydro-aeroplane. Collier owned a Wright Model B biplane which he purchased in 1911. Collier presented his namesake trophy several times before his death in 1918; after his World War I service. In 1922, when the Aero Club dissolved, the award was taken over ...

American Institute Of Aeronautics And Astronautics
The American Institute of Aeronautics and Astronautics (AIAA) is a professional society for the field of aerospace engineering. The AIAA is the U.S. representative on the International Astronautical Federation and the International Council of the Aeronautical Sciences. In 2015, it had more than 30,000 members among aerospace professionals worldwide (a majority are American and/or live in the United States). History The AIAA was founded in 1963 from the merger of two earlier societies: the American Rocket Society (ARS), founded in 1930 as the American Interplanetary Society (AIS), and the Institute of the Aerospace Sciences (IAS), founded in 1932 as the Institute of the Aeronautical Sciences. Paul Johnston was the first executive director of the organization. Jim Harford took his seat after 18 months. The newly-formed structure gathered 47 technical committees and one broad technical publication, the ''AIAA Journal''. The ''AIAA Student Journal'' was also launched in 1963. T ...

Society Of The Cincinnati
The Society of the Cincinnati is a fraternal, hereditary society founded in 1783 to commemorate the American Revolutionary War that saw the creation of the United States. Membership is largely restricted to descendants of military officers who served in the Continental Army. The Society has thirteen constituent societies in the United States and one in France. It was founded to perpetuate "the remembrance of this vast event" (the achievement of American Independence), "to preserve inviolate those exalted rights and liberties of human nature," and "to render permanent the cordial affection subsisting among the officers" of the Continental Army who served in the Revolutionary War. Now in its third century, the Society promotes public interest in the Revolution through its library and museum collections, publications, and other activities. It is the oldest patriotic, hereditary society in America. History The Society is named after Lucius Quinctius Cincinnatus, who left h ...
