Dawn-to-dusk Transcontinental Flight Across The United States
The "Dawn to dusk" transcontinental flight across the United States was a pioneering aviation record established June 23, 1924. It marked the first crossing of the North American continent within the hours of daylight. The record was set by 1st Lt. Russell L. Maughan, a U.S. Army Air Service test pilot at McCook Field, Dayton, Ohio, the site of the Air Service Engineering Division and its major flight-test center. Concept and flight plan The plan for the flight was conceived by the Air Service's Assistant Chief, Brig. Gen. Billy Mitchell in 1923. The Air Service since 1919 had been regularly establishing endurance, distance, altitude and speed records in airplanes to promote favorable publicity and public support for the funding of the U.S. Army War Department's Major Project Number 4, the Lassiter plan for the expansion of the Air Service. The year before Lt. James H. Doolittle had flown a DH-4 from Florida to San Diego in a single calendar day, making just one stop in Texas fo ...

PW-9
The Boeing Model 15 was a United States single-seat open-cockpit biplane fighter aircraft of the 1920s, manufactured by the Boeing company. The Model 15 saw service with the United States Army Air Service (as the PW-9 series) and with the United States Navy as a carrier-based fighter (as the FB series). Design and development The design of the Model 15 was based on studies of the Fokker D.VII, of which 142 were brought back to the U.S. for evaluation as part of the Armistice Agreement ending World War I. Many of the features were similar. The Model 15 had a fuselage of welded steel tubing braced with piano wire, while the tapered single bay wings were fabric on a wooden frame, with spruce and mahogany wing spars and three-ply wood ribs. Wing struts were changed from the normal wood used in Boeing designs to streamlined steel tubes. The landing gear had a straight axle, streamlined into a small chord wing. The original engine was a Wright-Hispano, but when the liquid-cooled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1st Operations Group
The 1st Operations Group (1 OG) is the flying component of the 1st Fighter Wing, assigned to the USAF Air Combat Command. The group is stationed at Langley Air Force Base, Virginia. The 1st Operations Group is the oldest major air combat unit in the United States Air Force, being the successor organization of the 1st Pursuit Group. The 1st Pursuit Group was the first air combat group formed by the Air Service, American Expeditionary Force, on 5 May 1918. The Group was first organized at Croix de Metz Aerodrome, near Toul, France, as a result of the United States entry into World War I. As the 1st Pursuit Group it saw combat on the Western Front in France, and during World War II as the 1st Fighter Group combat in the Mediterranean Theater of Operations.

Curtiss CR
The Curtiss CR was a racing aircraft designed for the United States Navy in 1921 by Curtiss. It was a conventional single-seater biplane with a monocoque fuselage and staggered single-bay wings of equal span braced with N-struts. Two essentially similar landplane versions were built as the CR-1 and CR-2, which were both eventually converted to seaplanes as the CR-3 in 1923 and CR-4 in 1924. A refined version was developed for the US Army Air Service under the designation R-6. These latter two aircraft featured refined aerodynamics included surface-mounted radiators. Operational history The Curtiss CRs enjoyed successful racing careers. Their first major win was at the 1921 Pulitzer Trophy race, where piloted by Bert Acosta the CR-1 took first place with an average speed of 176.75 mph (283.49 km/h), nearly two minutes ahead of its closest rival. The following year, this aircraft was modified and redesignated CR-2 and joined in the Pulitzer race by a second aircraft ...

Thomas-Morse MB-3
The Thomas-Morse MB-3 was an open-cockpit biplane fighter primarily manufactured by the Boeing Company for the U.S. Army Air Service in 1922. The MB-3A was the mainstay fighter for the Air Service between 1922 and 1925. Development In March 1918, the United States Army Air Service requested several American aircraft manufacturers to design a new fighter, to be powered by a water-cooled Wright-Hispano H, a license-built Hispano-Suiza 8, to replace the French-built SPAD XIII.Pelletier ''Air Enthusiast'' September–October 2007, p. 46.Angelucci and Bowers 1987, pp. 420–421.Dorr and Donald, 1990, p. 20. The Thomas-Morse Aircraft Corporation of Ithaca, New York proposed the MB-3, designed by its British-born chief designer B. Douglas Thomas, to meet this requirement, with an order for four prototypes being placed in September 1918.Wegg 1990, p. 24. The MB-3 was a single seat two- bay biplane of similar layout to the SPAD XIII that it was intended to replace. It was of wood and f ...

Curtiss P-5 Superhawk 060831-F-1234P-014
Curtiss Aeroplane and Motor Company (1909 – 1929) was an American aircraft manufacturer originally founded by Glenn Hammond Curtiss and Augustus Moore Herring in Hammondsport, New York. After significant commercial success in its first decades, it merged with the Wright Aeronautical to form Curtiss-Wright Corporation. History Origin In 1907, Glenn Curtiss was recruited by the scientist Dr. Alexander Graham Bell as a founding member of Bell's Aerial Experiment Association (AEA), with the intent of establishing an aeronautical research and development organization. According to Bell, it was a "co-operative scientific association, not for gain but for the love of the art and doing what we can to help one another."Milberry 1979, p 13. In 1909, shortly before the AEA was disbanded, Curtiss partnered with Augustus Moore Herring to form the Herring-Curtiss Company.Gunston 1993, p. 87. It was renamed the Curtiss Aeroplane Company in 1910 and reorganized in 1912 after being taken-o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbocharger
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a supercharger is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. History Prior to the invention of the turbocharger, |
