Arsenalul Aeronautic
Arsenalul Aeronautic ("Aeronautical Arsenal" in English) in Bucharest was the first factory with an aeronautical profile in Romania. Its activity took place between 1919 and 1939. ''Arsenalul Aeronautic'' manufactured three models of aircraft: Hansa-Brandenburg C.I, Proto 1 and Aeron and modified Airco DH.9, De Havilland aircraft for passenger and freight transport (aircraft intended for TAROM#The beginnings, domestic airlines). Also, at the Aeronautical Arsenal, research in the field of study and testing of materials was organized. History In November 1919, an aeronautical factory was created in Bucharest on the Militari, field of Cotroceni, as a result of the transfer of the material and the majority of the personnel of the ''Rezerva generală a aviației'' (General Aviation Reserve or RGA) from Iași. On 1 July 1920, the factory was renamed to the Aeronautical Arsenal. In the beginning, the activity was to repair different types of airplanes and aircraft engines from the endowm ...

Romaero
Romaero, formerly Intreprinderea de Reparații Material Aeronautic or IRMA ('Enterprise for the Repair of Aeronautical Material'), is a Romanian aerospace company, headquartered in the Băneasa neighborhood of Bucharest. In recent years, it has largely concentrated on aircraft repairs as well as component manufacturing for overseas companies. The company was founded by Royal Decree in 1920 under the name ''ASAM''. It was rebranded as IRMA in 1944. In 1978, the company again changed its name to ''IAvB – Întreprinderea de Avioane București'' ('Bucharest Enterprise Aircraft'). Finally, it was rebranded as ''Romaero S.A.'' in 1991. Perhaps the largest manufacturing programme that the company has been involved in was mass production of the British-designed Britten-Norman Islander; over 500 airframes were reportedly completed in Romania. Another major independent undertaking of the firm was the Rombac 111 airliner, a license-produced model of the BAC One-Eleven produced in Romani ...

Fabrica De Avioane Astra
The Astra Aircraft Factory () in Arad was the second Romanian factory to build aircraft. Its activity took place between 1923 and 1925, producing four models of aircraft: ''Astra-Șeșefschi'', Proto 1, Proto 2 and Astra-Proto. History From 1915, the ''Marta'' factory had been producing Austro-Daimler aircraft engines. After the war, the factory was merged with the '' Weitzer wagon'' factory, becoming '' Uzina de Vagoane Astra Arad'' (the Astra-Arad Wagon Factory). In 1923, ''Comandor'' Andrei Popovici, former commander of ''Grupul 2 Aeronautic'' (2nd Aeronautical Group) became the director of the factory, around the same time the construction of an aircraft prototype began. Conceived and designed by engineer Stanislav Șeșefschi, the aircraft was called ''Astra-Șeșefschi''. Next came the production of Proto 1 and Proto 2 airplanes. In 1925, Astra built the prototype ''Astra-Proto'', after the design by Major Ștefan Protopopescu. This machine did not reach serial producti ...

Fokker D
Fokker (; ) was a Dutch aircraft manufacturer that operated from 1912 to 1996. The company was founded by the Dutch aviator Anthony Fokker and became famous during World War I for its fighter aircraft. During its most successful period in the 1920s and 1930s, Fokker dominated the civil aviation market. The company's fortunes declined over the course of the late 20th century; it declared bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912. World War I Fokker capitalized on having sold several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varnish
Varnish is a clear Transparency (optics), transparent hard protective coating or film. It is not to be confused with wood stain. It usually has a yellowish shade due to the manufacturing process and materials used, but it may also be pigmented as desired. It is sold commercially in various shades. Varnish is primarily used as a wood finishing, wood finish where, stained or not, the distinctive tones and grains in the wood are intended to be visible. Varnish finishes are naturally Gloss (material appearance), glossy, but satin/semi-gloss and flat sheens are available. History The word "varnish" comes from Mediaeval Latin ''vernix'', meaning odorous resin, perhaps derived from Middle Greek ''berōnikón'' or ''beroníkē'', meaning amber or amber-colored glass. A false etymology traces the word to the Greek ''Berenice'', the ancient name of modern Benghazi in Libya, where the first varnishes in the Mediterranean area were supposedly used and where resins from the trees of now-v ...

Societatea Pentru Exploatări Tehnice
''Societatea Pentru Exploatări Technice'' or SET ("Technical Development Society") was a Romanian aircraft manufacturer. It was the second biggest Romanian pre-war aircraft manufacturer, after Industria Aeronautică Română (IAR). History The Societatea Pentru Exploatări Tehnice was established in Bucharest in 1923 by Grigore Zamfirescu as a general machinery manufacturing plant. It soon specialised in building aircraft to its founder's design, supplying the Romanian Air Force with trainers during the mid-1930s. At the peak of aircraft production, Zamfirescu changed the company's name to Fabrica de Avioane SET. In the late 1930s, SET abandoned producing its own designs, and manufactured a number of IAR and foreign types under licence, including the IAR 27, IAR 39, Fleet 10, and Nardi FN.305. In 1938, the company made a deal with the Romanian government that would have seen it relocate its manufacturing facilities to Moldavia, with the government promising to purchase a min ...

Bracing (aeronautics)
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplanes, including the monoplanes and biplanes, which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more ...

Salmson Water-cooled Aero-engines
The Salmson water-cooled aero-engines, produced in France by Salmson, Société des Moteurs Salmson from 1908 until 1920, were a series of pioneering aircraft engine, aero-engines: unusually combining water-cooled, water-cooling with the Radial engine, radial arrangement of their cylinders. History Henri Salmson, a manufacturer of water pumps, was engaged by Georges Marius Henri-Georges Canton and Pierre Unné, a pair of Switzerland, Swiss engineers, to produce engines to their design. Their initial efforts were on Axial engine, barrel engines, but these failed to meet expectations due to low reliability and high fuel consumption caused by internal friction. A new 7-cylinder water-cooled radial design was then developed by Canton and Unné. The range was expanded to produce 9-cylinder models, and also two-row 14-cylinder and 18-cylinder engines. By 1912 the Salmson A9 was producing around 120 brake horsepower; while competitive with rival designs from French companies, Salmson, Ca ...

Cirrus Aero Engines
The Cirrus and Hermes or Cirrus-Hermes are a series of British aero engines manufactured, under various changes of ownership, from the 1920s until the 1950s. The engines were all air-cooled, four-cylinder inline types, with earlier ones upright and later designs inverted. The first Cirrus design was created for the planned de Havilland Moth light aeroplane and, when it appeared in 1925, created the market for private flying. It and its successors were widely used for private and light aircraft from that moment on. Design and development ADC The Cirrus engine originated in Geoffrey de Havilland's 1924 quest for a powerplant suited to a light two-seat sports biplane which would become the de Havilland Moth. No suitable engine, combining a suitable power output with light weight, low cost and high reliability existed at the time. The Aircraft Disposal Company (also known as Airdisco and ADC) were producing the low-cost Airdisco V8 which had been developed by Frank Halford from their ...

Sesquiplane
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 ...
