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.

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s United States Experimental 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.

LeBlond 70-5
The LeBlond radial engines, later produced under the name Ken-Royce, were a family of 3-cylinder, 5-cylinder and 7-cylinder, air-cooled radial engines for aircraft, built in the 1930s by the LeBlond Aircraft Engine Corporation until the operation was sold to Rearwin Airplanes in 1937 and renamed Ken-Royce Engines.

South Bend Airport (NICTD)
South Bend Airport is a commuter train station on, and the eastern terminus of, the South Shore Line. Servicing South Bend International Airport, the station is northwest of Downtown South Bend, Indiana. In November 1992, the Airport station replaced the South Shore Line's former terminus at the South Bend Amtrak Station. The new station was constructed at a cost of $1.8 million and dedicated on November 20, 1992. The station has a waiting room. Because the station is incorporated into the South Bend International Airport building, riders can also take advantage of its extensive lounging areas, shops and a meditation room. Until November 27, 2009, most eastbound weekend South Shore Line trains terminated at this station. Since then, those trips have been cut in half, creating much larger gaps in service, to improve on-time performance for South Shore trains, which had suffered because the section of the line between Michigan City and South Bend is almost entirely single-track ...

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. The aircraft used a Clark Y airfoil th ... went out of business, Hatfield promised Snyder he would make one o ... [...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 ...

Sears
Sears, Roebuck and Co. ( ), commonly known as Sears, is an American chain of department stores founded in 1892 by Richard Warren Sears and Alvah Curtis Roebuck and reincorporated in 1906 by Richard Sears and Julius Rosenwald, with what began as a mail ordering catalog company migrating to opening retail locations in 1925, the first in Chicago. In 2005, the company was bought by the management of the American big box discount chain Kmart, which upon completion of the merger, formed Sears Holdings. Through the 1980s, Sears was the largest retailer in the United States. In 2018, it was the 31st-largest. After several years of declining sales, Sears's parent company filed for Chapter 11 bankruptcy on October 15, 2018. It announced on January 16, 2019, that it had won its bankruptcy auction, and that a reduced number of 425 stores would remain open, including 223 Sears stores. Sears was based in the Sears Tower in Chicago from 1973 until 1995, and is currently headquartered in Hof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jimmy Doolittle
James Harold Doolittle (December 14, 1896 – September 27, 1993) was an American military general and aviation pioneer who received the Medal of Honor for his daring raid on Japan during World War II. He also made early coast-to-coast flights, record-breaking speed flights, won many flying races, and helped develop and flight-test instrument flying. Raised in Nome, Alaska, Doolittle studied as an undergraduate at University of California, Berkeley, graduating with a Bachelor of Arts in 1922. He also earned a doctorate in aeronautics from the Massachusetts Institute of Technology in 1925, the first issued in the United States. In 1929, he pioneered the use of "blind flying", where a pilot relies on flight instruments alone, which later won him the Harmon Trophy and made all-weather airline operations practical. He was a flying instructor during World War I and a reserve officer in the United States Army Air Corps, but he was recalled to active duty during World War II. He was ...
