Nesmith Cougar
The Nesmith Cougar is a light aircraft that was developed in the United States in the 1950s and marketed for homebuilding. Development The design, by Robert Nesmith, is a conventional high-wing, strut-braced monoplane with fixed tailwheel undercarriage. The pilot and a single passenger were seated side by side. The fuselage and empennage were of welded steel-tube construction, while the wings were of wood, and the whole aircraft was fabric-covered. Some later aircraft were fitted with a tricycle undercarriage. The original Cougar design was marketed by Nesmith himself. His intent was to market a low-cost aircraft for homebuilders. He also used the aircraft as a troubled youth project to encourage teens to work together toward a goal. When a modified Cougar won an Experimental Aircraft Association (EAA) design competition in 1963, that organization took over selling plans. Rights to the design were eventually purchased by Acro Sport. The aircraft shape was influenced by the Beech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wittman Tailwind
The Wittman Tailwind is a popular two-seat light aircraft for homebuilding. It is a high-wing, braced cabin monoplane of taildragger configuration. It is constructed with a steel tubing fuselage, wood wings, and fabric covering. It offers exceptional cruising speeds and is economical to operate and maintain. Design and development The Tailwind is the third in a series of high-wing aircraft designed by Sylvester J. "Steve" Wittman (1904–1995), a well-known air racing pilot and race plane designer, who also played an important role in the emergence of homebuilt aircraft with the Wittman Tailwind and other designs in the United States. The first, the Wittman Buttercup two-seater, and later the Wittman Big X four-seater, which was bought by Cessna to use its spring steel landing gear. The Tailwind also inspired the last iteration, the O and O Special. A model of the 1965 Wittman Tailwind may be found in the Sun 'n Fun Museum. Wittman developed the C-85 powered "Flying Carpet ...

1950s United States Sport Aircraft
Year 195 ( CXCV) was a common year starting on Wednesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 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 has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger.

Scott Ol' Ironsides
The Scott Ol' Ironsides is an early homebuilt aircraft using wood construction with stressed fiberglass panel construction. Design Ol' Ironsides is a strut-braced high-wing aircraft with conventional landing gear arrangement. The wooden fuselage is made of Sitka Spruce. Fiberglass composite skins were formed in 4 x 8 sheets using two layers of cloth with resin over a waxed Masonite table. The landing gear legs, fuel tank, wink tips, wheel pants, and cowling were also formed out of fibre-glass. Scott integrated elements of the Bowers Fly Baby and Champion J-1 Jupiter construction with the Wittman Tailwind airfoil and general layout into the design. Operational history Construction of the aircraft was started in the mid-1960s starting with a model rather than a drawing. Ol' Ironsides first flew on 22 November 1969 with a Continental C-85 engine sourced from a Cessna 140. In 1985 the prototype aircraft was restored and re-engined with a Continental O-200 The Continental C90 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanson Woodwind
The Hanson Woodwind is an all-wooden homebuilt aircraft with a fiberglass wing. Design and development The Woodwind was a homebuilt copy of the Wittman Tailwind using all-wood construction, rather than welded steel tube and aircraft fabric covering for the fuselage. Ironically, the Wittman design uses plywood covering for its wings, while the Woodwind uses fiberglass. The Woodwind is a two-seat side-by-side configuration, strut-braced, high-wing aircraft with conventional landing gear and Plexiglas doors. Some construction elements were adapted from the all-wood Bowers Fly Baby. The fuselage sides and tail surfaces are built flat on a table at the same time and covered with aircraft grade plywood. The wings are covered in fiberglass with stainless steel torque tubes for aileron An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Szaraz SDS-1A Daphne
The Daphne SD-1A is a homebuilt aircraft that won second place in the 1970 EAA AirVenture Oshkosh flight efficiency contest. Design The Daphne is a two place, side-by-side configuration, strut-braced, high-wing, conventional landing gear equipped homebuilt. The fuselage is constructed of welded chromoly steel tubing, while the wings are made of wood, with one-piece plywood ribs. The entire structure is covered in aircraft fabric covering. Both ailerons and flaperons have been installed on the design. Hoerner wingtips were utilized, due to their inherent higher efficiency and low-drag features. Szaraz drew heavily from the design of the Wittman W-8 Tailwind during the design process, and thus the fuselage, landing gear, and engine mount are very similar to that of the W-8. Plans were first offered for sale in the March 1969 edition of Sport Aviation. In 1971, the plans were priced at $65, while the info packet was $2.

Wittman Buttercup
The Wittman W-5 Buttercup is a two place aircraft designed and built by Steve Wittman in 1938. Designated as the Buttercup Model W, the original aircraft is housed in the Experimental Aircraft Association, EAA AirVenture Museum in Oshkosh, WI. The Buttercup was considered as the basis for a four place certified production model by Fairchild Aircraft. Fairchild executives were impressed with the aircraft that chance landed at their factory airport in Hagerstown, Maryland. Wittman sold production rights, but Fairchild did not pursue the effort due to wartime production obligations. Experimental Aircraft Association member Earl Luce Jr. developed a replica Buttercup design, which first flew on April 14, 2002. He made a set of plans for his design, available for home builders. On 28 May 2023, 70-year-old Earl Luce Jr., said to be an excellent pilot, and his passenger were killed when the buttercup crashed as he was flying over Orleans County, New York, US.

Bede BD-4
The Bede BD-4 is an American light aircraft, designed by Jim Bede for homebuilding and available since 1968. It was one of the first homebuilt aircraft to be offered in kit form. It remains one of the world's most popular homebuilts with thousands of plans sold and hundreds of examples completed to date. Design and development Based on his previous work with innovative light aircraft, the BD-1 (eventually developed into the American Aviation AA-1 Yankee) and BD-2, Jim Bede designed the BD-4 to be one of the first real "kitplanes" in the world. (AOPA has credited the design of the BD-4 to aeronautical inventor Dave Blanton."AOPA members in the news," in "Pilot Briefing," August 5, 1997, ''AOPA Pilot.'' |
Flat-four
A flat-four engine, also known as a horizontally opposed-four engine or boxer engine, is a four-cylinder piston engine with two banks of cylinders lying on opposite sides of a common crankshaft. The most common type of flat-four engine is the boxer-four engine, each pair of opposed pistons moves inwards and outwards at the same time. A boxer-four engine has perfect primary and secondary balance, however, the two cylinder heads means the design is more expensive to produce than a straight-four engine. There is a minor, secondary unbalanced rotational torque pulse in the plane of the pistons, when a piston pair at one end of the engine is at TDC and the other pair at BDC. The TDC pair creates a torque greater than the BDC pair, so the net unbalanced torque pulse is the difference. The difference in TDC vs BDC inertial forces is explained in the Engine balance section. Boxer-four engines have been used in cars since 1897, especially by Volkswagen and Subaru. They have also occasional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Culver Cadet
The Culver Cadet is an American two-seat light monoplane aircraft, also as a radio-controlled drone, produced by the Culver Aircraft Company. Design and development The aircraft designer Al Mooney developed an improved version of the Culver Dart, to provide improved performance with a smaller engine. Originally designated the Culver Model L, the prototype first flew on 2 December 1939. The aircraft was named the Culver Cadet. Although similar to the previous Dart, the Cadet had a semi-monocoque fuselage instead of welded-steel-tube, and a retractable tailwheel undercarriage. The first variant (the Cadet LCA) was powered by a 75 hp (56 kW) Continental A75-8 four-cylinder horizontally opposed piston engine. The 1941 version was designated the Cadet LFA, introducing a number of refinements and more equipment, and was fitted with a 90 hp (67 kW) Franklin engine. Production was brought to an end after the United States entered World War II in December 1941, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
