RWD (aircraft Manufacturer)
RWD was a Polish aircraft construction bureau active between 1928 and 1939. It started as a team of three young designers, Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki, whose names formed the RWD acronym. History They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (''Sekcja Lotnicza Koła Mechaników Studentów''), where they manufactured their first designs. From 1926 they designed several aircraft alone ( Drzewiecki JD-2 and WR-1), in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Okęcie aerodrome, today's Warsaw International Airport, founded by the LOPP paramilitary organization. ...

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] |
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 ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Straight Engine
The straight or inline engine is an internal combustion engine with all cylinders aligned in one row and having no offset. Usually found in four, six and eight cylinder configurations, they have been used in automobiles, locomotives and aircraft, although the term in-line has a broader meaning when applied to aircraft engines, see Inline engine (aviation). Design A straight engine is considerably easier to build than an otherwise equivalent horizontally opposed or V engine, because both the cylinder bank and crankshaft can be milled from a single metal casting, and it requires fewer cylinder heads and camshafts. In-line engines are also smaller in overall physical dimensions than designs such as the radial, and can be mounted in any direction. Straight configurations are simpler than their V-shaped counterparts. Although six-cylinder engines are inherently balanced, the four-cylinder models are inherently off balance and rough, unlike 90-degree V fours and horizontally oppos ...

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 ...

1930s Polish Sport 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.

Arado Ar 79
The Arado Ar 79 was a German aircraft of the 1930s, designed as an aerobatic two-seat trainer and touring aircraft.Donald, p. 60. The Ar 79 was a monoplane with retractable, tailwheel undercarriage. The wings were constructed of fabric over plywood, the forward fuselage was of fabric over steel tube, and the rear fuselage was a monocoque structure. Operational history The Ar 79 set a number of speed records in 1938: *On 15 July the solo 1,000 km (621.4 mi) at 229.04 km/h (142.32 mph), *On 29 July the 2,000 km (1,242.8 mi) at 227.029 km/h (141.069 mph). *From 29 to 31 December, a modified Ar 79, with a jettisonable 106 L (28 US gal) fuel tank and extra 520 L (140 US gal) tank behind the cabin, completed a non-stop 6,303 km (3,917 mi) flight from Benghazi, Libya to Gaya, India, at an average speed of 160 km/h (100 mph).

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 ''empenner'' 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. 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 floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...
