XB-19
The Douglas XB-19 was a four-engined, piston-driven heavy bomber produced by the Douglas Aircraft Company for the United States Army Air Forces (USAAF) during the early 1940s. It was the largest bomber built for the USAAF until 1946, and was originally given the designation XBLR-2 (''XBLR'' denoting "Experimental Bomber Long Range"). Design and development The XB-19 project was intended to test flight characteristics and design techniques for giant bombers. Despite advances in technology that made the XB-19 obsolete before it was completed, the Army Air Corps believed the prototype would be useful for testing despite Douglas Aircraft wanting to cancel the expensive project. Its construction took so long that competition for the contracts to build the XB-35 and XB-36 occurred two months before its first flight. The plane first flew on 27 June 1941, more than three years after the construction contract was awarded. It was based at Wright Field from January to November 1942. In ...

Wright R-3350-5 Duplex Cyclone
The Wright R-3350 Duplex-Cyclone is an American twin-row, supercharged, air-cooled, radial aircraft engine with 18 cylinders displacing nearly . Power ranged from 2,200 to over 3,700 hp (1,640 to 2,760 kW), depending on the model. Developed before World War II, the R-3350's design required a long time to mature before finally being used to power the Boeing B-29 Superfortress. After the war, the engine had matured sufficiently to become a major civilian airliner design, notably in its turbo-compound forms, and was used in the Lockheed L-1049 Super Constellation airliners into the 1990s. The engine is commonly used on Hawker Sea Fury and Grumman F8F Bearcat Unlimited Class Racers at the Reno Air Races. Its main rival was the , Pratt & Whitney R-4360 Wasp Major, first run some seven years after the Duplex-Cyclone's beginnings. Design and development In 1927, Wright Aeronautical introduced its famous "Cyclone" engine, which powered a number of designs in the 1930s. ...

Allison V-3420
The Allison V-3420 was a large experimental piston aircraft engine, designed in 1937 by the American Allison Engine Company. Design and development In 1937, at the behest of the United States Army Air Corps, the Allison Engine Company agreed to design and build a large-displacement high-power aircraft engine. The resulting V-3420 was essentially a pair of 12-cylinder Allison V-1710 engines mated to a common crankcase with a 30° angle between the inner cylinder banks. The crankshafts of the two V-1710 engines were geared together to drive a common propeller shaft. Most V-3420 parts were interchangeable with those for V-1710-E and -F engines. The V-3420 had a power-to-weight ratio of 1.6 kW/kg or 1 hp/lb, excellent for its time. It was envisioned as a powerful yet compact engine for several advanced USAAF projects of the day, including the Douglas XB-19, the Boeing XB-39 Superfortress, the Lockheed XP-58 Chain Lightning, and the Fisher P-75 Eagle.

Wright Field
Wilbur Wright Field was a military installation and an airfield used as a World War I pilot, mechanic, and armorer training facility and, under different designations, conducted United States Army Air Corps and Air Forces flight testing. Located near Riverside, Ohio, the site is officially "Area B" of Wright-Patterson Air Force Base and includes the National Museum of the United States Air Force built on the airfield. History World War I Wilbur Wright Field was established in 1917 for World War I on of land adjacent to the Mad River which included the 1910 Wright Brothers' Huffman Prairie Flying Field and that was leased to the Army by the Miami Conservancy District. Logistics support to Wilbur Wright Field was by the adjacent Fairfield Aviation General Supply Depot established in January 1918 and which also supplied three other Midwest Signal Corps aviation schools. A Signal Corps Aviation School began in June 1917 for providing combat pilots to the Western Front in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Douglas Aircraft Company
The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas; it then operated as a division of McDonnell Douglas. McDonnell Douglas later merged with Boeing in 1997. History 1920s The company was founded as the Douglas Company by Donald Wills Douglas Sr. on July 22, 1921 in Santa Monica, California, following dissolution of the Davis-Douglas Company. An early claim to fame was the first circumnavigation of the world by air in Douglas airplanes in 1924. In 1923, the U.S. Army Air Service was interested in carrying out a mission to circumnavigate the Earth for the first time by aircraft, a program called "World Flight". Donald Douglas proposed a modified Douglas DT to meet the Army's needs. The two-place, open cockpit DT biplane torpedo bomber had previously been produced for the U.S. Navy.Rumerman, Judy.

Boeing Y1B-20
The Boeing Y1B-20 (Boeing 316) was designed as an improvement on the Boeing XB-15 The Boeing Company () is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, satellites, telecommunications equipment, and missiles worldwide. The company also provides leasing and product ... (''Y1-'' indicates a funding source outside normal fiscal year procurement.) It was slightly larger than its predecessor, and was intended to use much more powerful engines. It was presented to the Army in early 1938, and two orders were placed soon after. The order was reversed before construction began. Despite their cancellation, the XB-15 and Y1B-20 laid the groundwork for the Boeing B-29 Superfortress.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Dayton, Ohio
Dayton () is the sixth-largest city in the U.S. state of Ohio and the county seat of Montgomery County. A small part of the city extends into Greene County. The 2020 U.S. census estimate put the city population at 137,644, while Greater Dayton was estimated to be at 814,049 residents. The Combined Statistical Area (CSA) was 1,086,512. This makes Dayton the fourth-largest metropolitan area in Ohio and 73rd in the United States. Dayton is within Ohio's Miami Valley region, north of the Greater Cincinnati area. Ohio's borders are within of roughly 60 percent of the country's population and manufacturing infrastructure, making the Dayton area a logistical centroid for manufacturers, suppliers, and shippers. Dayton also hosts significant research and development in fields like industrial, aeronautical, and astronautical engineering that have led to many technological innovations. Much of this innovation is due in part to Wright-Patterson Air Force Base and its place in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M2 Browning Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
