Marquardt Corporation
Marquardt Corporation was an aeronautical engineering firm started in 1944 as ‘’’Marquardt Aircraft Company’’’ and initially dedicated almost entirely to the development of the ramjet engine. Marquardt designs were developed from the mid-1940s into the early 1960s, but as the ramjet disappeared from military usage, the company turned to other fields. In 1968 Marquardt was merged with CCI Inc. of Tulsa, OK. The newly merged firm became known as "CCI-Marquardt, Inc.". That name changed back to "CCI Inc." after a few years. Throughout the 1970s and 1980s pieces of Marquardt were sold off or merged with other firms. By the 1990s, one of the remnants of the company, called ''Marquardt Manufacturing Inc.'' (MMI) was embroiled in a legal suit with its predecessor organization, which had become principally a landlord who owned the buildings and land where MMI was located. By then, most of the remaining pieces of Marquardt were part of Ferranti in England which was in bankrup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

P-51 Mustang
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October. The Mustang was designed to use the Allison V-1710 engine, which had limited high-altitude performance in its earlier variants. The aircraft was first flown operationally by the RAF as a tactical-reconnaissance aircraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timm Aircraft
The O.W. Timm Aircraft Company was an American aircraft manufacturer founded by Otto William Timm, based in Los Angeles, California. History Between 1911 and 1922 O.W. Timm built several aircraft with varying success before he founded, in 1922, the O.W. Timm Aircraft Company. Timm manufactured six models of a parasol design, the Collegiate. In 1934 Otto and his brother Wally Timm joined to form a new company named the Timm Airplane Company to produce the Timm T-S140, a high wing twin engine aircraft using new features developed at NACA such as flaps and tricycle landing gear. Wally Timm formed his own Glendale based aviation company later on, the Wally Timm Inc. The company developed a "plastic" material made of resin and wood similar to the Duramold process. The Duramold and Haskelite process was first developed in 1937. Followed by Gene Vidal's Weldwood and later the Aeromold process. The Aeromold process differs in that it is baked at a low at cutting and forming, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Van Nuys
Van Nuys () is a neighborhood in the central San Fernando Valley region of Los Angeles, California. Home to Van Nuys Airport and the Valley Municipal Building, it is the most populous neighborhood in the San Fernando Valley. History In 1909, the Suburban Homes Company – a syndicate led by Hobart Johnstone Whitley, general manager of the board of control, along with Harry Chandler, H. G. Otis, M. H. Sherman and O. F. Brandt – purchased 48,000 acres of the Farming and Milling Company for $2.5 million. Henry E. Huntington extended his Pacific Electric Railway (Red Cars) through the Valley to Owensmouth (now Canoga Park). The Suburban Home Company laid out plans for roads and the towns of Van Nuys, Reseda (Marian) and Canoga Park (Owensmouth). The rural areas were annexed into the city of Los Angeles in 1915. The town was founded in 1911 and named for Isaac Newton Van Nuys, a rancher, entrepreneur and one of its developers. It was annexed by Los Angeles on May 22, 1 ...

Shock Wave
In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and density of the medium. For the purpose of comparison, in supersonic flows, additional increased expansion may be achieved through an expansion fan, also known as a Prandtl–Meyer expansion fan. The accompanying expansion wave may approach and eventually collide and recombine with the shock wave, creating a process of destructive interference. The sonic boom associated with the passage of a supersonic aircraft is a type of sound wave produced by constructive interference. Unlike solitons (another kind of nonlinear wave), the energy and speed of a shock wave alone dissipates relatively quickly with distance. When a shock wave passes throug ...

Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
P-80 Shooting Star
The Lockheed P-80 Shooting Star was the first jet fighter used operationally by the United States Army Air Forces (USAAF) during World War II. Designed and built by Lockheed in 1943 and delivered just 143 days from the start of design, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II. Designed with straight wings, the type saw extensive combat in Korea with the United States Air Force (USAF) as the F-80. America's first successful turbojet-powered combat aircraft, it was soon outclassed with the appearance of the swept-wing transonic MiG-15 and was quickly replaced in the air superiority role by the transonic F-86 Sabre. The F-94 Starfire, an all-weather interceptor using the same airframe, also saw Korean War service. The closely related T-33 Shooting Star trainer remained in service with the U.S. Air Force and Navy well into the 1980s, with the last NT-33 variant not retired until Apr ...

United States Air Force
The United States Air Force (USAF) is the Aerial warfare, air military branch, service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps (United States Army), Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, intelligence, surveillance, target acquisition, and reconnaissance, global integrated intelligence, surveillance and reconnaissance, airlift, rapid global mobility, Strategic bombing, global strike, and command and control. The United States Air Force is a military service branch organized within the United States Department of the Air Force, De ...

PTV-N-2 Gorgon IV
The PTV-N-2 Gorgon IV was a subsonic ramjet-powered missile developed by the Glenn L. Martin Company for the United States Navy. Originally intended as an air-to-surface weapon, it materialized as a propulsion test vehicle, and between 1947 and 1950 was used for test purposes and, as the KDM Plover, as a target drone. Design and development Development of the Gorgon IV began in May 1945, when the U.S. Navy's Bureau of Aeronautics contracted with the Glenn L. Martin Company, as part of Project Gorgon, to develop an air-to-surface missile, powered by a ramjet engine and using active radar homing for guidance. The end of World War II saw a reduction in need for such a weapon, however the contract was continued in 1946 as a propulsion test vehicle, originally designated KUM-1, then PTV-2 before finally being redesignated PTV-N-2.Parsch 2005 The PTV-N-2 was of fairly conventional design, with mildly-swept wings and a conventional empennage; roll control was through spoilerons.
