Milt Hatfield Little Bird
The Hatfield Little Bird aircraft are a continuation of the Arup series of low aspect ratio aircraft. Development In the late 1920s, Cloyd Snyder of South Bend, Indiana developed a series of "Heel Lift" low aspect ratio aircraft inspired by the gliding properties of felt heel inserts. South Bend native, Milt Hatfield had built a homebuilt aircraft at the same time. Seeking flying lessons while grounded by his father, he donated parts of his aircraft to the Arup S-2 project in exchange for flying lessons. Years later, Hatfield taught the buyer of the S-2 how to fly the plane, and salvaged parts from his own plane to keep it going. After Arup Manufacturing Corporation Arup Manufacturing Corporation was an American aircraft manufacturer of tailless aircraft. History Dr. C.L. Snyder experimented with tailless aircraft starting with a 1926 glider called the Dirigiplane.

Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

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 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arup Manufacturing Corporation
Arup Manufacturing Corporation was an American aircraft manufacturer of tailless aircraft. History Dr. C.L. Snyder experimented with tailless aircraft starting with a 1926 glider called the Dirigiplane. The aircraft used a Clark Y airfoil that could be filled with helium gas to assist with lift. Snyder formed the Monowing corporation to further develop the aircraft. The design progressed into the Arup S-1 design and the formation of Arup Manufacturing. In 1934, Snyder's chief engineer, Raoul J. Hoffman left the company to create a similar design, the 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 Trimotot .... His breakaway project ended with the crash of the prototype from an onboard fire.

Arup S-1
The Arup S-1, also called the Snyder Glider and the Dirigiplane was the first in a series of "Heel Lift" vehicles developed by Dr. Cloyd Snyder. Development Snyder was a podiatrist in South Bend, Indiana. He was inspired in 1926 by the gliding properties of heel-lifts to develop a full size aircraft. Experimentation was performed on balsa-wood aircraft, followed by wind testing on the hood of a car, at South Bend Central High School and finally at Michigan University. Students at the school, led by S. M. Pierce, tested and built a wood and fabric glider based on the designs. Design The glider featured two wooden parallel trusses running along its spine, with two widely spaced truss wing spars. Wing ribs were attached to the spar with varnished shoelaces. The wing shape featured a straight leading edge with the trailing edge tapering back to the tail giving it a distinctive "Half Pie" appearance from the top. The vertical stabilizers were low, but ran the full length of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

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 ...

Low-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 ...
