Grumman Vehicles
The Grumman Aircraft Engineering Corporation, later Grumman Aerospace Corporation, was a 20th century American producer of military and civilian aircraft. Founded on December 6, 1929, by Leroy Grumman and his business partners, it merged in 1994 with Northrop Corporation to form Northrop Grumman. History Leroy Grumman worked for the Loening Aircraft Engineering Corporation beginning in 1920. In 1929, Keystone Aircraft Corporation bought Loening Aircraft and moved its operations from New York City to Bristol, Pennsylvania.

Northrop Corporation
Northrop Corporation was an American aircraft manufacturer from its formation in 1939 until its 1994 merger with Grumman to form Northrop Grumman. The company is known for its development of the flying wing design, most successfully the B-2 Spirit stealth bomber.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 93-106, Cypress, CA, 2013. . History Jack Northrop founded 3 companies using his name. The first was the Avion Corporation in 1928, which was absorbed in 1929 by the United Aircraft and Transport Corporation as a subsidiary named "Northrop Aircraft Corporation" (and later became part of Boeing). The parent company moved its operations to Kansas in 1931, and so Jack, along with Donald Douglas, established a "Northrop Corporation" located in El Segundo, California, which produced several successful designs, including the Northrop Gamma and Northrop Delta. However, labor difficulties led to the dissolution of the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Columbia Field
Columbia Field, originally Curtiss Field, is a former airfield near Valley Stream within the Town of Hempstead on Long Island, New York. Between 1929 and 1933 it was a public airfield named Curtiss Field after the Curtiss-Wright aircraft corporation that owned it. The public airfield closed after 1933, but aircraft continued to be manufactured there primarily by Columbia Aircraft Corporation, which gave the private airfield its name. During its five years of operation, Curtiss Field was one of the busiest airports on Long Island. The airfield was popular with many of the famous pilots of the early days of aviation including Charles Lindbergh, Amelia Earhart, and Frank Hawks. Several important long-distance aviation records or events were marked at the airfield. In 1929 the women's aviation group the Ninety Nines was founded at the airfield, and large airshows were often held there. After 1933 the airfield was the site of aviation manufacturing by Columbia Aircraft and Grumma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also ...

Grumman FF-1
The Grumman FF "Fifi" (company designation G-5) was an American biplane fighter aircraft operated by the United States Navy during the 1930s.Eden and Moeng 2002, p. 762. It was the first carrier aircraft with retractable landing gear.Winchester 2002, p. 21. It was produced under licence in Canada and known as the Goblin in Canadian service and Delfín (English: "Dolphin") in Spanish service. Design and development The ''FF-1'' was Grumman’s first complete aircraft design for the US Navy. The Navy had asked Grumman if their retractable landing gear made for the O2U-1 Scout planes could be retrofitted to the Navy's Boeing F4B-1 fighters; instead Grumman proposed a new fighter design. The prototype ''XFF-1'' (serial number A8878) was built to a contract placed on 22 April 1931, first flying on 29 December of that year,Cacutt 1989, p. 155–162.Swanborough and Bowers 1976, p. 195. a two-seat design, with an enclosed cockpit, fuselage of all-metal construction, and wings covered la ...

Baldwin, Nassau County, New York
Baldwin is a hamlet and census-designated place (CDP) located in the Town of Hempstead in Nassau County, on Long Island, in New York, United States. The population was 33,919 at the time of the 2020 census. History Original inhabitants of the area between Parsonage Creek near Oceanside and Milburn Creek near Freeport were Native Americans known as the Meroke, or Merrick, a band of Lenape people who were indigenous to most of the South Shore of Long Island. They spoke an Algonquian language and lived in two villages along Milburn Creek. In 1643, English colonists began to call this area Hick's Neck, after two of Hempstead's early settlers, John Spragg from England and John Hicks from Flushing, New York. They extended Hempstead village south to the salt meadows. The grist mill built by John Pine in 1686 on Milburn Creek attracted more English settlers. They engaged in fishing, farming, marshing, raising longwood, and breeding and raising sheep. Between the American Revolutiona ...

Cox-Klemin
The Cox-Klemin Aircraft Corporation was an American aircraft manufacturer based in Long Island, New York in the 1920s. History It was founded by Charles Cox and Alexander Klemin (a professor at New York University) in College Point, New York. The company took over an ordnance plant in Baldwin, New York in 1924. Later that year, it partnered with Ernst Heinkel to design and build a mailplane. In defiance of prohibition, the company christened its new Nighthawk airplane using champagne in 1925. The company filed for bankruptcy in 1925. However, bankruptcy proceedings continued into 1926. The case was further delayed after the court could not locate company management.

Bristol, Pennsylvania
Bristol is a borough in Bucks County, Pennsylvania, United States. It is located northeast of Center City Philadelphia, opposite Burlington, New Jersey on the Delaware River. It antedates Philadelphia, being settled in 1681 and first incorporated in 1720. After 1834, it became very important to the development of the American Industrial Revolution as the terminus city of the Delaware Canal, providing greater Philadelphia with the day's high tech anthracite fuels from the Lehigh Canal via Easton. The canal and a short trip on the Delaware also gave the town access to the mineral resources available in Connecticut, New Jersey and New York via each of the Morris Canal, the Delaware and Hudson Canal, and the Delaware and Raritan Canal, and connected the community to those markets and trade from New York City. Although its charter was revised in 1905, the original charter remains in effect, making it the third-oldest borough in Pennsylvania after Chester and Germantown. It had 7 ...
