Northrop Aircraft
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 three 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 Northrop, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial, and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, maintain, and repair both aircraft and spacecraft. The border between space and the atmosphere has been proposed as above the ground according to the physical explanation that the air density is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. This border has been called the Kármán line. Overview In most industrial countries, the aerospace industry is a co-operation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space A ...

El Segundo, California
El Segundo ( , ; ) is a city in Los Angeles County, California, United States. Located on Santa Monica Bay, it was incorporated on January 18, 1917, and is part of the South Bay Cities Council of Governments. The population was 17,272 as of the 2020 census, a 3.7% increase from 16,654 in the 2010 census. A significant center of the oil and aerospace industries in Southern California, roughly three quarters of the city's land is dedicated exclusively to industrial and commercial uses, including a Chevron oil refinery which alone takes up more than a quarter of the entire city. History The El Segundo and Los Angeles coastal area was first settled by the Tongva (or Gabrieleños) Native American tribes. The area was once a part of '' Rancho Sausal Redondo'' ("Round Willow Patch Ranch"). Rancho Sausal Redondo extended from Playa Del Rey in the north to Redondo Beach in the south. Originally a Mexican land grant owned by Antonio Ygnacio Avila, the rancho was later purchased by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop F-89 Scorpion
The Northrop F-89 Scorpion is an night fighter, all-weather, twin-engined interceptor aircraft designed and produced by the American aircraft manufacturer Northrop Corporation. It was the first jet propulsion, jet-powered aircraft to be designed for the interceptor role from the outset to enter service, as well as the first combat aircraft to be armed with air-to-air nuclear weapons in the form of the unguided AIR-2 Genie, Genie rocket. The name ''Scorpion'' came from the aircraft's elevated tail unit and high-mounted horizontal stabilizer, which kept it clear of the engine exhaust.Knaack 1978, p. 82. The Scorpion was designed by Northrop in response to a specification issued by the United States Army Air Forces (USAAF) during August 1945. Internally designated as the ''N-24'', it was originally designed with a relatively slim fuselage, buried Allison J35 turbojet engines, and a swept wing configuration, however, the unfavorable low speed characteristics of this wing led to its ...

Northrop YB-49
The Northrop YB-49 was an American prototype jet-powered heavy bomber developed by Northrop Corporation shortly after World War II for service with the United States Air Force. The YB-49 featured a flying wing design and was a turbojet-powered development of the earlier, piston-engined Northrop XB-35 and YB-35. The two YB-49s built were both converted YB-35 test aircraft. The YB-49 never entered production, being passed over in favor of the more conventional Convair B-36 piston-driven design. Design work performed during the development of the YB-35 and YB-49 nonetheless proved invaluable to Northrop decades later when the company was tasked with developing the B-2 stealth bomber, which entered service in the early 1990s. Design and development With the XB-35 program seriously behind schedule by 1944, and the end of piston-engined combat aircraft in sight, the production contract for this propeller-driven type was cancelled in May of that year. Nevertheless, the Flying Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop YB-35
The Northrop YB-35, Northrop designation N-9 or NS-9, was an experimental heavy bomber aircraft developed by the Northrop Corporation for the United States Army Air Forces during and shortly after World War II. The airplane used the radical and potentially very efficient flying wing design, in which the tail section and fuselage are eliminated and all payload is carried in a thick wing. Only prototypes and pre-production aircraft were built, although interest remained strong enough to warrant further development of the design as a jet bomber, under the designation YB-49.Parker, Dana T. ''Building Victory: Aircraft Manufacturing in the Los Angeles Area in World War II,'' pp. 93, 95, 103–6, Cypress, CA, 2013. . Design and development The B-35 was the brainchild of Jack Northrop, who made the flying wing the focus of his work during the 1930s. In 1941, before the United States entered World War II, Northrop and Consolidated Vultee Corporation had been commissioned to develop a ...

Night Fighter
A night fighter (later known as all-weather fighter or all-weather interceptor post-Second World War) is a largely historical term for a fighter aircraft, fighter or interceptor aircraft adapted or designed for effective use at night, during periods of adverse meteorological conditions, or in otherwise poor visibility. Such designs were in direct contrast to day fighter, day fighters: fighters and interceptors designed primarily for use during the day or during good weather. The concept of the night fighter was developed and experimented with during the First World War but would not see widespread use until WWII. The term would be supplanted by “all-weather fighter/interceptor” post-WWII, with advancements in various technologies permitting the use of such aircraft in virtually all conditions. During the Second World War, night fighters were either purpose-built night fighter designs, or more commonly, heavy fighters or light bombers adapted for the mission, often employing ...

Northrop P-61 Black Widow
The Northrop P-61 Black Widow is a twin-engine United States Army Air Forces fighter aircraft of World War II. It was the first operational U.S. warplane designed specifically as a night fighter. Named for the North American spider '' Latrodectus mactans'', it was an all-metal, twin-engine, twin-boom design armed with four forward-firing 20 mm (.79 in) Hispano M2 autocannon in the lower fuselage, and four M2 Browning machine guns in a dorsal gun turret. Developed during the war, the first test flight was made on 26 May 1942, with the first production aircraft rolling off the assembly line in October 1943. Although not produced in the large numbers of its contemporaries, the Black Widow was operated effectively as a night fighter by United States Army Air Forces squadrons in the European Theater, Pacific Theater, China Burma India Theater, and Mediterranean Theater during World War II. It replaced earlier British-designed night-fighter aircraft that had been up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
