Fairchild KR-21
The Kreider-Reisner KR-21-A was a 1928 American two-seat monoplane. It was designed and built by the Kreider-Reisner Aircraft Company of Hagerstown, Maryland. Fairchild Aircraft took over Kreider-Reisner in 1929 and continued to build them, as the Fairchild KR-21, later the Fairchild 21. Design and development The KR-21-A was a low-wing braced monoplane with two open tandem cockpits and powered by a 100 hp (60 kW) Kinner K-5 radial piston engine. It was of mixed construction and had a fixed tailwheel landing gear and was fitted with dual controls. The KR-21-B was a more powerful biplane development, using a 125 bhp Kinner B-5 engine. Five were produced, three built as -B models and two converted from the -A. At least three, most of the production, survive today * NC107M * NC236V * NC954V The KR-21 would in turn form the basis of the KR-22 parasol-wing monoplane A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplan ...

Tandem Cockpit
Tandem, or in tandem, is an arrangement in which a team of machines, animals or people are lined up one behind another, all facing in the same direction. The original use of the term in English was in ''tandem harness'', which is used for two or more draft horses, or other draft animals, harnessed in a single line one behind another, as opposed to a pair, harnessed side by side, or a team of several pairs. The tandem harness allows additional animals to provide pulling power for a vehicle designed for a single animal. The English word ''tandem'' derives from the Latin adverb , meaning ''at length'' or ''finally''. It is a word play, using the Latin phrase (referring to time, not position) for English "at length, lengthwise". Tandem bicycles are named for their tandem seating, a more common arrangement than side-by-side "sociable" seating. ''Tandem'' can also be used more generally to refer to any group of persons or objects working together, not necessarily in line. Automob ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

Kinner B-5
The Kinner B-5 was a popular five cylinder American radial engine for light general and sport aircraft of the 1930s. Design and development The B-5 was a development of the earlier K-5 with slightly greater power and dimensions. The main change was the increase in cylinder bore from 108 mm (4.25 in) to 117 mm (4.625 in) and a corresponding increase in displacement from 372 cu in (6.1 liters ) to 441 cu in (7.2 liters ). One difference the B-5 had from radial engines of other manufacturers was that each individual cylinder had its own camshaft, a system also used by the contemporary Soviet-built, 8.6 litre-displacement Shvetsov M-11 five cylinder radial, while most other radial engine designs used a "cam ring" for the same purpose, connected to every cylinder's valves. The B-5 was a rough running but reliable engine. The B-5 and its derivatives were produced in the thousands, powering many World War II trainer aircraft; its military designation was R-440. The ...

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] |
Kinner K-5
The Kinner K-5 was a popular engine for light general and sport aircraft developed by Winfield B. 'Bert' Kinner. With the boom in civilian aviation after Charles Lindbergh's transatlantic flight the K-5 sold well. The K-5 was a rough running but reliable engine and the K-5 and its derivatives were produced in the thousands, powering many World War II trainer aircraft.

Experimental Aircraft Association
The Experimental Aircraft Association (EAA) is an international organization of aviation enthusiasts based in Oshkosh, Wisconsin, United States. Since its inception, it has grown internationally with over 200,000 members and nearly 1,000 chapters worldwide. It hosts the largest aviation gathering of its kind in the world, EAA AirVenture Oshkosh. History The EAA was founded in 1953 by veteran aviator Paul Poberezny along with other aviation enthusiasts. The organization began as more or less a flying club. Poberezny explains the nature of the organization's name, "Because the planes we flew were modified or built from scratch, they were required to display an EXPERIMENTAL placard where it could be seen on the door or cockpit, so it was quite natural that we call ourselves the "Experimental Aircraft Association". The EAA was incorporated in Wisconsin on 22 March 1955. Homebuilding is still a large part of EAA, but the organization has grown over the years to include almost every ...

Hagerstown, Maryland
Hagerstown is a city in Washington County, Maryland, United States and the county seat of Washington County. The population of Hagerstown city proper at the 2020 census was 43,527, and the population of the Hagerstown metropolitan area (extending into West Virginia) was 269,140. Hagerstown ranks as Maryland's sixth-largest incorporated city and is the largest city in the Panhandle. Hagerstown has a distinct topography, formed by stone ridges running from northeast to southwest through the center of town. Geography accordingly bounds its neighborhoods. These ridges consist of upper Stonehenge limestone. Many of the older buildings were built from this stone, which is easily quarried and dressed onsite. It whitens in weathering and the edgewise conglomerate and wavy laminae become distinctly visible, giving a handsome and uniquely "Cumberland Valley" appearance. Several of Hagerstown's churches are constructed of Stonehenge limestone. Its value and beauty as building rock may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kreider-Reisner Aircraft Company
The Kreider-Reisner Aircraft Company was an American flying service and aircraft manufacturer from 1923 to 1929. History The Kreider-Reisner Aircraft Company was formed at Hagerstown, Maryland in 1923 as a sub-contractor. By September 1925 the company was operating a general flying service and incorporated. In 1926 it designed and built the first aircraft the Midget lightplane. The aircraft performed well in aviation competitions so the company then designed a two-seat utility biplane. It had decided it was cheaper to design and build an aircraft for use in its own flying services and the resulting aircraft was the C-2 Challenger. A smaller version was designed and built in 1928 as the C-6 Challenger. On 1 April 1929 the company was bought by the Fairchild Aircraft Company who continued production at Hagerstown and redesignated the aircraft in a Fairchild KR series. Kreider remained president, but died on 13 April 1929 in a mid-air collision. Reisner left the company shortly af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
