Piper PA-21
The Baumann Brigadier was a prototype American light transport aircraft of the late 1940s. It was a twin-engined monoplane, which, unusually, was of pusher configuration. Only two were built, plans for production never coming to fruition. Development and design Jack Baumann, who had worked for the Taylor Aircraft Company (later to become Piper Aircraft) and Lockheed, set up the Baumann Aircraft Corporation in Pacoima, Los Angeles, California in 1945. His first design for the new company was the B-250 Brigadier, a twin-engined pusher monoplane intended as an executive transport. It was of all-metal construction, with cantilever shoulder mounted wings, and with the pusher engines mounted in nacelles on the wing. An enclosed cabin accommodated a pilot and four passengers, while the aircraft was fitted with a retractable nosewheel undercarriage. The first prototype, powered by two engines (hence the B-250 designation) flew on 20 June 1947. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Willard Ray Custer
Willard Ray Custer (, Warfordsburg, Pennsylvania, Hagerstown, Maryland) was an American engineer and aircraft visionary, inventor of the channel wing concept. Custer left school at age 13, working as a blacksmith and, later, an engineer and mechanic. The inspiration to the channel wing concept came in 1925 when Custer had observed how the roof of a barn was lifted during a very strong gust of wind. He started investigating the phenomenon and, by 1928, he had developed the first Model of a new airplane wing for which he received a patent in 1929. This channel wing managed much lift even at very low airspeeds, and allowed start and landing on very short airfields. In 1939 Custer founded the ''National Aircraft Corporation'' and, on , started development of the CCW-1 (CusterChannelWing 1) experimental aircraft. With the CCW-2 that followed, he could achieve almost vertical starts, and flight almost like a helicopter. The military started a number of trials which were subsequently ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1940s United States Civil Utility Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

Leonard Bridgman
Leonard Bridgman (1895–1980) was a British artist and the editor of Jane's All the World's Aircraft from 1941 to 1959. First assignment Bridgman's first assignment in aviation was in 1913 at the age of 18 years. One of his drawings was used to illustrate the Hendon Air Race program. As payment, he received a flight in a 70-horsepower Maurice Farman biplane. Career in the army During the First World War, Bridgman served as an officer in the Honourable Artillery Company The Honourable Artillery Company (HAC) is a reserve regiment in the British Army.

Flat-six Engine
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 ''Wilson-Pilcher 18/24 HP'' car. The most notable use of flat-six engines is the Porsche 911 sports car, which has used flat-six engines continuously since 1963. Several o ...

Continental C145-H
The Continental O-300 and the C145 are a family of air-cooled flat-6 aircraft piston engines built by Teledyne Continental Motors.Christy, Joe: ''Engines for Homebuilt Aircraft & Ultralights'', pages 60-63. TAB Books, 1983. First produced in 1947, versions were still in production . It was produced under licence in the United Kingdom by Rolls-Royce in the 1960s. Development The C-145 was developed from the C-125 engine. Both powerplants share the same crankcase, although the C-145 produces an additional through a longer piston stroke, higher compression ratio of 7.0:1 and different carburetor jetting. The O-300 is a modernized C-145 and retains the same weight, dimensions, bore, stroke, compression ratio, displacement and output power of the earlier engine. GO-300 The GO-300 employs a reduction gearbox, so that the engine turns at 3200 rpm to produce a propeller rpm of 2400. The GO-300 produces whereas the ungeared O-300 produces .

The Continental O-470 engine is a family of carbureted and fuel-injected six-cylinder, horizontally opposed, air-cooled aircraft engines that was developed especially for use in light aircraft by Continental Motors. Engines designated "IO" are fuel-injected. The family also includes the E165, E185, E225 and the E260 engines, and several specialty variants. It has been in production since 1950. Design and development The first engine in this series was the E165, a 471 cubic inch (7.7 L) engine producing , and was the first of the Continental's "E" series engines. Later versions were given the company designation of E185 ( continuous) and E225 (). When the US military gave them all the designation of O-470 the company adopted the designation and future models were known as Continental O-470s. The O-470 family of engines covers a range from to . The engines were developed in the late 1940s and certification was applied for on 23 October 1950 on the regulatory basis of Part 1 ...
