Wittemann-Lewis Training Tractor
The Wittemann-Lewis Training Tractor (sometimes referred to as the T-T) is an American two-seat military training biplane designed and built by the Wittemann-Lewis Aircraft Company. Design The Training Tractor was designed as a military training biplane, a conventional tractor biplane with two-open cockpits in tandem. It had a square section fuselage and a 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 Term ... with a tailskid. The Training Tractor was powered by a Hall-Scott A-7 engine mounted in the nose. It was not ordered into production.

Trainer (aircraft)
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft. Civilian pilots are normally trained in a light aircraft, with two or more seats to allow for a student and instructor. Tandem and side by side The two seating configurations for trainer aircraft are: pilot and instructor side by side, or in tandem, usually with the pilot in front and the instructor behind. The side-by-side seating configuration has the advantage that pilot and instructor can see each other's actions, allowing the pilot to learn from the instructor and the instructor to correct the student pilot. The tandem configuration has the advantage of being closer to the normal working environment that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplane
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 ...

Wittemann-Lewis
The Wittemann-Lewis Aircraft Company was an American aircraft manufacturer between 1906 and 1923. It was notable for building two large aircraft, the Sundstedt-Hannevig transatlantic seaplane with a 100-foot wingspan and the NBL-1 Barling Bomber a six-engined triplane with a 120-foot wingspan. Early years The company had been formed at Staten Island, New York in 1906 by Charles Rudolph Wittemann, Charles and Adolph Wittemann as Wittemann Aeronautical Engineers. The first aircraft built was a Wright pusher biplane in 1907, unusual for the time it had a swivelling tail wheel. A series of Wright pusher triplanes were built between 1908 and 1914 for a number of notable aviators. In 1911 they built a number of Hall-Scott pusher biplanes for Thomas Baldwin, known as the Baldwin Red Devil for the red-doped covering. Between 1913 and 1914 they built several Curtis-type biplanes. Around 1917 Adolph Wittemann left the company and Charles was joined by Samuel Lewis and they became the Witte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye.

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] |
Hall-Scott A-7
The Hall-Scott A-7 was an early liquid-cooled aircraft engine manufactured by the Hall-Scott company of Berkeley, California. Using a straight-4 configuration, the engine developed 90 horsepower (67 kW) as the A-7 and 100 horsepower (75 kW) as the A-7a. In service these engines suffered from reliability problems and were prone to catch fire while in operation. Variants * A-7: The A-7 used the same cylinders as the earlier Hall-Scott A-5. Bore: , stroke: , displacement: , weight: , power: at 1,400 rpm, weight: * A-7a: The A-7a used the same cylinders as the earlier Hall-Scott A-5a. Applications * Aeromarine 39 (A-7a) * Aeromarine M-1 (A-7a) * Dayton-Wright FS (A-7a) * Standard J-1 In 2017 about seven A-7a engines were still in use in Edwardian racing cars, mostly in the United Kingdom.

1910s United States Military Trainer Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 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. Events By place Parthia * King Vologases IV of Parthia dies after a 44-year reign, and is succeeded by his son Vologases V. China * A coalition of Chinese warlords from the east of Hangu Pass launches a punitive campaign against the warlord Dong Zhuo, who seized control of the central government in 189, and held the figurehead Emperor Xian hostage. After suffering some defeats against the coalition forces, Dong Zhuo forcefully relocates the imperial capital from Luoyang to Chang'an.
