Pobjoy Special
The Nicholas-Beazley Pobjoy Special aka the Nicholas-Beazley Phantom I, aka the Wittman Phantom, aka the Flagg Phantom, aka the Reaver Special was a world record holding air racer of the 1930s Development The Nicholas-Beazley Airplane Company had imported a Pobjoy Airmotors engine with a gear reduction unit for use in its new design the Nicholas-Beazley NB-3. Designer Robert T. Jones computed the weight and balance for the setup and proposed a new design as an air-racer. Claude Flagg and H. F. Landis built the aircraft in their spare time and patented the wing design. Design The fuselage is welded steel with fabric covering. The wings used an early application of lightweight aluminum construction with U shaped cantilever spars with wire bracing and fabric covering. The aircraft used wheels with small tires and without brakes. The cockpit was open and the engine was fully cowled. In 1932 the Pobjoy P engine was replaced with a Pobjoy R of 75 hp. The cockpit was also enclo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pobjoy R
The Pobjoy R is a British seven-cylinder air-cooled radial aircraft engine designed and built by Pobjoy Airmotors. Introduced in 1926, it was a popular engine for ultralight and small aircraft in the 1930s. A notable feature of the Pobjoy R was the propeller reduction gear which allowed the small engine to operate at more desirable higher speeds. The engine was license produced in Czechoslovakia by Walter Aircraft Engines as the Walter Mira.

1930s United States Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.

Pobjoy Niagara
The Pobjoy Niagara is a British seven-cylinder, air-cooled, radial, aero-engine first produced in 1934. The design ran at higher speeds than conventional engines, and used reduction gearing to lower the speed of the propeller. This led to a noticeable off-centre mounting for the propeller. The Niagara was a popular engine for light and experimental aircraft, well regarded due to its small diameter, smooth operation, low noise and innovative engineering. Variants ;Niagara I :Bore/stroke 77 x 87 mm (3.03 x 3.43 in), swept volume 2,835 cc (173 cu in). Compression 6.25:1, gearing 0.47:1.

Oshkosh, Wisconsin
Oshkosh is a city in Winnebago County, Wisconsin, of which it is the county seat. The city had a population of 66,816 in 2020, making it the ninth-largest city in Wisconsin. It is also adjacent to the Town of Oshkosh. History Oshkosh was named for Menominee Chief Oshkosh, whose name meant "claw" (cf. Ojibwe ''oshkanzh'', "the claw"). Although the fur trade attracted the first European settlers to the area as early as 1818, it never became a major player in the fur trade. The 1820s mining boom in southwest Wisconsin along with the opening of the Erie Canal shifted commercial activity away from the Fox River Valley and Green Bay. Soon after 1830, much of the trade moved west, as there had been over-trapping in the region. Following the publicity caused by the Black Hawk War in 1832, there was increased interest in settling Wisconsin by whites from the East Coast, especially New York, Indiana, and Virginia, and by 1836 the cities of Milwaukee, Madison, Janesville, Beloi ...

EAA Airventure Museum
The EAA Aviation Museum, formerly the EAA AirVenture Museum (or Air Adventure Museum), is a museum dedicated to the preservation and display of historic and experimental aircraft as well as antiques, classics, and warbirds. The museum is located in Oshkosh, Wisconsin, United States, adjacent to Wittman Regional Airport, home of the museum's sponsoring organization, the Experimental Aircraft Association (EAA), and the organization's EAA AirVenture Oshkosh event (the world's biggest fly-in and airshow) that takes place in late July/early August. With over 200 aircraft, indoors and outdoors, and other exhibits and activities (including occasional aircraft rides nearby), the AirVenture Museum is a key tourist attraction in Oshkosh and is a center of activity throughout the AirVenture fly-in and airshow each summer.

Formula One Air Racing
Formula One Air Racing is an American motorsport that involves small aircraft using engines up to in displacement. Racers can reach speeds over 200 mph. History Formula One air racing is sanctioned by the International Aeronautics Federation. Formula One was first proposed in 1936 as "midget racing". The 190 Cubic in specification was set in 1946, and the first competition was set in 1947. Some 1930s air racers, like the Chester Jeep and Loose Special were retrofitted with smaller engines to compete. With the introduction of the Continental O-200 The Continental C90 and O-200 are a family of air-cooled, horizontally opposed, four-cylinder, direct-drive aircraft engines of 201 in³ (3.29 L) displacement, producing between 90 and 100 horsepower (67 and 75 kW).''Federal Aviation Admini ... engine, the maximum engine displacement was raised to 200 cubic inches in 1968.

Steve Wittman
Sylvester Joseph "Steve" Wittman (April 5, 1904 – April 27, 1995) was an American air-racer and aircraft engineer. An illness in Wittman's infancy claimed most of his vision in one eye, which convinced him from an early age that his dream of flying was unattainable. However, he learned how to fly in 1924 in a Standard J-1 and built his first aircraft, the Harley-powered "Hardly Abelson" in late 1924. From 1925 to 1927, he had his own flying service, giving joyrides, and during this time also became a demonstration and test pilot for The Pheasant Aircraft Company and Dayton Aircraft Company, flying the Pheasant H-10 in multiple events. He also began his air-racing career, flying his first race in 1926 at a Milwaukee event in his J-1. After competing in his first transcontinental air race from New York to Los Angeles in 1928, he attained a medical waiver on his eyesight and received his pilot's certificate soon after (signed by Orville Wright).Wisconsin Aviation Hall of ...

Continental C-85
The Continental O-190 (Company designations C75 and C85) is a series of engines made by Continental Motors beginning in the 1940s. Of flat-four configuration, the engines produced 75 hp (56 kW) or 85 hp (63 kW) respectively.Teledyne Continental Motors: ''Continental Aircraft Engine Operator's Manual'', pages 4-5. Teledyne Continental Motors, FAA Approved December 1980. Continental Form No. X30012 The two variants shared the same bore, stroke and compression ratio. The C85 produced ten extra horsepower by virtue of having a maximum permissible rpm of 2575 versus the 2275 of the C75. The C75 was in production from 1943 to 1952 and the C85 from 1944 to 1970.

Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...
