Franklin 6A4 150-B3
The Franklin O-335 (company designations variations on 6A and 6V) was an American air-cooled aircraft engine of the 1940s. The engine was of six-cylinder, horizontally-opposed layout and displaced . The power output of later variants was . Design and development These engines were commonly vertically mounted and used to power many early helicopters in the United States. They were closely related to the 2A4 and 4A4 2- and 4-cylinder engines. In various subtypes, the 6A4 remained in continuous production from 1945 to the time Franklin's United States operations ceased in 1975, with versions continuing in Polish production into the 1990s. In 1947 this engine was modified into a water-cooled version by the Tucker Car Corporation for use in the 1948 Tucker Sedan. Tucker liked the engine so much that he purchased the Aircooled Motors/Franklin Engine Company The Franklin Engine Company was an American manufacturer of aircraft engines.

Bellanca Cruisair
The Bellanca 14-7 Cruisair and its successors were a family of single-engined light aircraft manufactured in the United States from the mid-1930s onwards.Palmer 2001, p. 51. Design and development Bellanca established itself in the market for 6-8 seat aircraft, but believed that it could also successfully sell smaller 3-4 seat aircraft. To fill this niche Bellanca designed The '14-7 Cruisair' as a modern, low-wing cantilever monoplane with a fuselage intended to contribute lift to the design. Although the prototype flew with fixed tailwheel undercarriage, the 14-9 production version was the first US light aircraft to be mass-produced with retractable undercarriage, the main wheels rotating aft into wheel-wells in the wings, with approximately 50 produced before production was interrupted by World War II. After WWII Bellanca resumed production with the up-dated Bellanca 14-13 Cruisair Senior, retaining the Bellanca 14-7's basic design, featuring an enlarged cabin, a horizont ...

Taylorcraft 15
Taylorcraft Aviation is an airplane manufacturer that has been producing aircraft for more than 70 years in several locations. The company builds small single-engined airplanes. The Taylorcraft design is a conventional layout: high-wing, fabric-covered, two-seat aircraft. The basic design has remained unchanged since 1936, and this design is sold as a personal sport aircraft today. History The designer, Clarence Gilbert Taylor, a self-taught aeronautical engineer born in Rochester, New York, to parents who immigrated from England, can be called the father of private aviation in America, as he designed the original Taylor Cub in 1931 at Bradford, Pennsylvania. Taylor, along with his brother Gordon, formed Taylor Brothers Aircraft Corporation - slogan; "Buy Your Airplane Taylor Made" - in Rochester, New York in 1926, offering a two-seat high-winged monoplane called the "Chummy", priced at $4,000. The Chummy failed to sell, and after Gordon died flying another Taylor design in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sznycer SG-VI
The Sznycer SG-VI (aka Sznycer-Gottlieb SG-VI) was a single-engined three-seat utility helicopter designed and built in the United States and Canada in the late 1940s to the design of Bernard Sznycer, assisted by Selma Gottlieb and Engineering Products of Canada Ltd. (CanAmerican) Design & development Initial design work on the SG-VI began at Philadelphia in 1943 by a team led by Bernard Sznycer, including Selma Gottlieb, Harold Pitcairn and Agnew Larsen. Pitcairn and Larsen left the partnership by August 1945 when Sznycer and Intercity Airlines of Montreal, Quebec, Canada, signed a contract for the detailed design, testing and certification of a prototype helicopter to be marketed and built by the Canadian helicopter Company. The contract did not develop as planned and the first prototype, the SG-VI-C, was built by Engineering Products of Canada Ltd., (a BF. Goodrich subsidiary at Montreal).

Stinson Voyager
The Stinson Voyager was a 1940s American light utility monoplane built by the Stinson Aircraft Company. Development First developed as the Stinson HW-75 and marketed as the Model 105 in 1939, the design was a high-wing three-seat braced monoplane powered by either a 75-hp (63.4-Kw) Continental A-75 or an 80-hp (67.7-Kw) Continental A-80-6. This was developed into the Model 10 powered by a Continental A-80 piston engine. The Model 10 introduced a wider cabin as well as an improved standard for the interior and finish.Orbis 1985, p. 2960. The Model 10 was followed by the Model 10A, powered by a Franklin 4AC-199 engine and the Model 10B with a Lycoming GO-145. The 10A was the last of the series, but the first to be called "Voyager", a name that was retained for the post-war Stinson 108. Six Model 10s were evaluated by the United States Army Air Forces (USAAF) as the YO-54. The unsuccessful tests led Stinson to design an all-new aircraft designated Model 76, later known as the L- ...

Seibel S-4
The Seibel S-4 was a two-bladed, single-engine helicopter built by Seibel Helicopter. Designed by Charles Seibel, the S-4 was evaluated by the United States Army under the designation ''YH-24 Sky Hawk'', but would be rejected for service. The S-4B would serve as the basis for the design of the Cessna CH-1 Skyhook, the only helicopter Cessna ever produced. Development Charles Seibel began development on the S-4 after forming the Seibel Helicopter Company with funding from local Kansas oil investors. The S-4 was a continuation of his work on his previous design, the Seibel S-3, which he flew as a demonstrator for his design concepts; primarily a new design for a two-bladed rotor system and a simplified transmission. These features would also be incorporated into the S-4 design. In January 1949, the S-4 lifted off the ground for the first time, piloted by Johnny Gibbs. In March 1950, certification tests were completed and on 23 April 1950, the S-4 received civil certification by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
