Arup S-2
The Arup S-2 was the first commercial development of Cloyd Snyder's Arup S-1 low aspect ratio wing aircraft. Design The Arup S-2 featured a straight leading edge wing with a trailing edge that tapered to the rear of the aircraft giving it a guitar pick shape when viewed from above. An M6 airfoil was chosen over its predecessor's sharp edged, modified Clark-Y airfoil. The large trailing edge control surfaces were mixed for pitch and roll control, but were assisted by small, movable, semi-circular wingtips that could provide additional roll control. Conventional landing gear was used, faired with wheel pants. The access to the cockpit was from a belly mounted hatch. Visibility was enhanced with celluloid panels on the aircraft's belly. Operational history The prototype S-2 was test flown by Glen Doolittle. The STOL aircraft could fly at up to 35 degrees angle of attack without stalling. The aircraft was demonstrated across the country at events like the Indianapolis 500 and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoffman Flying Wing
Raoul J. Hoffman was a Hungary-born hebrew engineer who moved to the United States of America and is notable for the aircraft he designed or helped to design. Aircraft design Hoffman helped develop the Laird Super Solution racer, and Owl Trimototor. Later he worked for C.L. Snyder's company Arup Manufacturing Corporation, developing a series of tailless aircraft known as the Arup S-1, and S-2. When diagnosed with tuberculosis, Hoffman moved to St. Petersburg, Florida and developed his own version for a customer in Chicago, Illinois. After poor performance, and arson destroying the Arup S-3 follow-on, Hoffman returned to Arup to develop the Arup S-4. Hoffman's aircraft The aircraft which Hoffman designed during his absence from Arup was of similar tailless semi-circular "heel wing" configuration to the Arup designs. It is sometimes mistakenly described as a flying wing, but in fact it has a pronounced fuselage nacelle protruding above and forward of the wing. Design and develop ...

Mid-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of 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 can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Chyeranovskii BICh-7
The BICh-7 was a tailless sport/touring aircraft designed and built in the USSR from 1929. Development Chyeranovskii designed an enlarged BICh-3 The BICh-3 (russian: БИЧ-3) was a tailless research aircraft designed and built in the USSR The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia f ..., at approximately 1.5 scale, with tandem open cockpits, underslung elevons (à la Junkers) centreline mono-wheel, wing-tip rudders with skids with no tail. Flight testing commenced in 1929 but was soon halted due to the very poor handling characteristics which rendered the BICh-7 almost impossible to take off. The BICh-7 was completely rebuilt as the BICh-7A, modifications included: enclosed tandem cockpits, a conventional style tail-skid undercarriage, and a fin with rudder faired into the rear of the cockpit nacelle. Flight tests resumed, in 1932, with much improved handling other th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arup S-4
The Arup S-4 (Model 104) is the last in a series of round-wing aircraft from C.L. Snyder. Design and development The S-4 was engineered by Raoul Hoffman. The test pilot was Glenn Doolittle, a cousin of Jimmy Doolittle. The S-4 used a low aspect ratio, semi-circular planform wing with a conventional landing gear and a small rudder with attached elevator on the rear of the fuselage. The aircraft was entered through a door mounted on the bottom of the aircraft. Operational history The S-4 prototype flew extensively in promotional demonstrations. The S-4 was emblazoned with Sears Roebuck and Company logos. The aircraft was scrapped for war materials in World War II. Variants * Hoffman Flying Wing a design based on the Arup S-4 aircraft. * Milt Hatfield Little Bird The Hatfield Little Bird aircraft are a continuation of the Arup series of low aspect ratio aircraft.

Arup S-3
The Arup S-3 was the third in a series of low aspect ratio aircraft developed by Dr. Snyder of South Bend, Indiana. Design and development Raoul Hoffman worked to engineer the Arup S-2 with Dr. Snyder. Around 1933 he was diagnosed with tuberculosis and left the company for the warmer climate of Florida where he developed his own variation, the Hoffman Flying Wing. He was replaced by Ralph Graigen to develop the next generation of the aircraft. The S-3 featured a straight leading edge with the trailing edge tapering back to the rear of the aircraft, giving it a thumbnail like appearance from the top. The aircraft featured a tall tricycle landing gear with a small tailwheel in case of over-rotation on takeoff. The fabric covered fuselage was made of welded steel tube with wooden wing ribs. The S-3 differed from the S-2 in that it included a small rudder and elevator at the rear of the fuselage, rather than placing all of the controls on the low aspect ratio wing. The fuselage was ...

Lifting Body
A lifting body is a fixed-wing aircraft or spacecraft configuration in which the body itself produces lift. In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage with little or no conventional wing. Whereas a flying wing seeks to maximize cruise efficiency at subsonic speeds by eliminating non-lifting surfaces, lifting bodies generally minimize the drag and structure of a wing for subsonic, supersonic and hypersonic flight, or spacecraft re-entry. All of these flight regimes pose challenges for proper flight safety. Lifting bodies were a major area of research in the 1960s and 70s as a means to build a small and lightweight crewed spacecraft. The US built a number of lifting body rocket planes to test the concept, as well as several rocket-launched re-entry vehicles that were tested over the Pacific. Interest waned as the US Air Force lost interest in the crewed mission, and major development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental A-40
The Continental A40 engine is a carbureted four-cylinder, horizontally opposed, air-cooled aircraft engine that was developed especially for use in light aircraft by Continental Motors. It was produced between 1931 and 1941. Design and development The A40 was introduced in the depths of the Great Depression. At the time there were a number of small engines available but all suffered from either high cost, complexity, or low reliability. The A-40 addressed all those shortcomings and was instrumental in the production of light aircraft in the difficult economic constraints of the period. The A-40-4 introduced an increase in power to . The engine later inspired the A-50 and subsequent engines.Christy, Joe: ''Engines for Homebuilt Aircraft & Ultralights'', pages 8-9. TAB Books, 1983. The A40 featured single ignition until the A-40-5 version, which introduced dual ignition.

Old Rhinebeck Aerodrome
The Old Rhinebeck Aerodrome is a living museum in Rhinebeck, New York. It owns many examples of airworthy aircraft of the Pioneer Era, World War I and the Golden Age of Aviation between the World Wars, and multiple examples of roadworthy antique automobiles. History The aerodrome was the creation of Cole Palen, who was partially inspired by the Shuttleworth Collection in England. He regularly flew many of the aircraft during weekend airshows as his alter-ego, "The Black Baron of Rhinebeck" (loosely based on the Red Baron). These airshows still continue mid-June through mid-October, and biplane rides are available before and after the shows. The simple early shows led to a philosophy of not only showing the aircraft in their natural environment, but also providing a fun and entertaining day out for the whole family. From this the series of weekend air shows that the Old Rhinebeck Aerodrome featured — still running to this day — was to become famous for what was developed. T ...

American Eagle Eaglet
The Eaglet 31 was a United States two-seat tandem ultra-light high-winged monoplane of the early 1930s. Intended as a low-cost aircraft, its limited production run relegated it to a footnote in aviation history. Design and development The American Eagle Aircraft Corporation found that demand for their A-129 biplane and their other models was badly affected by the Wall Street stockmarket crash of late 1929 which ushered in the Great Depression. The small ultra-light, tandem two-seat Eaglet was therefore designed by company president, Edward E. Porterfield, to appeal to pilots with more modest pockets. Porterfield set a realistic goal of manufacturing an aircraft for $1,000. The first advertised price was $995.00. The first model was the 1930 Eaglet 230, initially powered by the 25 h.p. Cleone engine that flew on June 30, 1930. The engine was so underpowered that only solo flights were possible.Underwood 1968,, p. 62. Most later Eaglet 230s featured a 30 h.p. "Zeke" Sze ...
