Doświadczalne Warsztaty Lotnicze
''Doświadczalne Warsztaty Lotnicze'' (DWL) ('Experimental Aeronautical Workshops') was the Polish aircraft manufacturer, active in 1933–1939. It was a home of the RWD construction team and manufactured aircraft under a brand RWD. History The RWD construction team was organized of students of Warsaw University of Technology around 1928. They built their first designs in workshops of the Aviation Section of Students' Mechanical Club, in University buildings. In 1930 the workshops moved to new buildings near Okęcie airport in Warsaw, founded by the LOPP organization. In March 1933 the workshops separated from the Aviation Section and the University, and there was created a company ''Doświadczalne Warsztaty Lotnicze'' to manufacture RWD aircraft. Main designers were Stanisław Rogalski and Jerzy Drzewiecki of the RWD team, other designers were Bronisław Żurakowski, Tadeusz Chylinski, Leszek Dulęba and Andrzej Anczutin and several engineers, including Henry Millicer. ...

Straight Engine
The straight engine (also called inline engine) is a configuration of multi-cylinder piston engine where all of the cylinders are arranged in a single row, rather than radially or in two or more cylinder banks. Design A straight engine is easier to build than an equivalent flat engine or V engine, as it uses one cylinder head rather than two. Inline engines are also narrower than flat engines or V engines; however, they are longer and can be taller. The engine balance characteristics of a straight engine depend on the number of cylinders and the firing interval. Slant engines and horizontally-mounted engines When a straight engine is mounted at an angle from the vertical it is called a ''slant engine''. Notable slant engines include the 1959-2000 Chrysler Slant-6 engine, 1961-63 Pontiac Trophy 4 engine and the 1968-1981 Triumph Slant-4 engine. Some buses and diesel multiple unit trains take this concept further by mounting the engines horizontally (i.e. with a slant ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple wings. 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 (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1930s Polish Sport Aircraft
Year 193 ( CXCIII) was a common year starting on Monday 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. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor.

De Havilland Gipsy Major I
The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inverted inline engine used in a variety of light aircraft produced in the 1930s, including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types. Engines were produced by de Havilland in the UK and by the Australian arm of the company, de Havilland Australia, the latter modifying the design to use imperial measures rather than the original metric measurements. Design and development The engine was a slightly modified Gipsy III, which was effectively a de Havilland Gipsy engine modified to run inverted so that the cylinders pointed downwards below the crankcase. The Major was also bored-out (118 mm from 114 mm) compared to the Gipsy III, increasing displacement from 5 L to 6.1 L. The inverted configuration allowed the propeller shaft to be kept in a high position without having the cylinders blocking the pilot's forward view over the nose of the aircraf ...

Arado Ar 79
The Arado Ar 79 was an aerobatic two-seat trainer and touring aircraft designed and produced by the German aircraft manufacturer Arado.Donald 1997, p. 60. It was the final civilian aircraft developed by the company. The Ar 79 was developed during the mid-1930s as a successor to the Arado L I and Arado L II touring aircraft by the aeronautical engineer Walter Rethel. He designed a monoplane with a retractable tailwheel undercarriage that featured mixed construction, the forward fuselage was composed of fabric over steel tube while the rear fuselage was a monocoque structure. The Ar 79 was a relatively durable, light weight, and economical aircraft that possessed favourable flight characteristics. It had a fully-glazed cabin integral with the fuselage, a dedicated luggage compartment, and a pair of fuel tanks within the fuselage. While primarily intended as a civil aircraft, its use as a military trainer was not excluded. First flying in April 1938, the Ar 79 promptly set multi ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect.

Tadeusz Chyliński
Tadeusz Chylińnski (13 October 1911 in Warsaw – 15 February 1978 in Warsaw) – was a Polish airplane designer and constructor, a researcher at the Institute of Aviation, Warsaw, Institute of Aviation in Warsaw and specialist in aircraft structures. Before World War II Chyliński was the son of Stanisław Kazimierz and Zofia J. ''née'' Tuszowski. In 1920, went to the Muszyński School in Warsaw. After a year he moved to Milanówek (suburb of Warsaw), where his parents bought the "Afrykanka" (literally: ''African woman'') estate, and where he attended the coeducational Classical High School. In 1926, he returned to Warsaw to continue his education in the school of Ludwik Lorentz "Lorencowka", from which he graduated in 1930. He began studies at the University of Warsaw, but in 1931 he moved to the Mechanical Division of the Warsaw University of Technology and its aeronautical school. During his studies, he obtained a glider pilot license in Sokola Góra near Krzemieniec. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empennage
The empennage ( or ), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 194. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', p. 10 (27th revised edition) The term derives from the French language verb which means " to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces. In spite of effective control surfaces, many early aircraft that lacked a stabilising empennage were virtually unflyable. Even so-called "tailless aircraft" usually have a tail fin (usually a vertical stabiliser). Heavier-than-air aircraft without any kind of empennage (such as the Northrop B-2) are rare, and generally use specially ...
