Darjawna Aeroplanna Rabotilniza
Darzhavna aeroplanna rabotilnitsa (''Държавна аеропланна работилница'' - State Aircraft Workshops), abbreviated DAR (''ДАР''), was the first Bulgarian aircraft manufacturer, established in 1924 at Bojourishte. History Initially involved in repairing German aircraft then in use in Bulgaria, DAR soon began producing copies of some of these (DAR Uzunov-1, DAR 2), before moving on to licensed production of the Focke-Wulf Fw 44. The workshops produced a number of original designs, some of these were produced (DAR 1, DAR 3, DAR 4, DAR 6, , DAR 9, DAR 11), while others never proceeded past prototype stage (DAR 5, DAR 7, DAR 10). Although aircraft manufacture was moved to the Darzhavna Samoletna Fabrika (''Държавна самолетна фабрика'' - State Airplane Factory, abbr. ''ДСФ'' - DSF) in Lovech in 1940, designers remained in DAR. was DAR's head designer towards the end of the organisation's lifespan. Amongst others, he was respo ...

Aerospace
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...

Lovech
Lovech ( bg, Ловеч, Lovech, ) is a List of cities and towns in Bulgaria, city in north-central Bulgaria. It is the administrative centre of the Lovech Province and of the subordinate Lovech Municipality. The city is located about northeast from the capital city of Sofia. Near Lovech are the towns of Pleven, Troyan and Teteven. Name The name is possibly derived from the Slavic root ''lov'', "hunting" + the Slavic suffix ''-ech''. Geography Lovech is situated in the Balkan Mountains, Forebalkan area of northern Bulgaria, on both sides of the river Osam, and unifies both mountainous and plain relief. The eastern part of the town is surrounded by a 250 m high plateau, where the largest park in Lovech, ''Stratesh'', is located, and the southwestern part is surrounded by the hills ''Hisarya'' and ''Bash Bunar''. In the northwest the relief gradually changes to the plains of the neighbouring Pleven Province. The average altitude of Lovech is about 200 m above mean sea level. The ...

Government-owned Companies Of Bulgaria
State ownership, also called government ownership and public ownership, is the ownership of an industry, asset, or enterprise by the state or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership. In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company's shares. This form is often referred to as a state-owne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Manufacturers Of Bulgaria
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

DAR 11 Lyastovitsa
The Avia B.135 ( RLM designation Av-135) was a Czechoslovak cantilever monoplane fighter aircraft. It was the production version of the Avia B.35 developed shortly before the war, based on the B.35/3 prototype but featuring a new all-metal wing. History The B.135/1 prototype attracted the attention of Bulgarian Air Force officers visiting the Avia plant, and a production contract for 12 aircraft and 62 engines was signed, as well as a license to allow an additional 50 airframes to be constructed by DAR as the DAR 11 ''Lyastovitsa'' (Bulgarian: "Лястовица"; "Swallow"). However, the DAR facilities proved to be incapable of producing the aircraft, and only the 12 Czech-built examples were ever made. Plans for further production were stopped by the RLM, which also interrupted engine deliveries after 35 units, and the Bulgarian Air Force was encouraged to purchase the Messerschmitt Bf 109 instead. Operational history In service, the B.135s had continual engine problems and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DAR 9 Siniger
__NOTOC__ The DAR-9 Siniger, was a trainer produced in Bulgaria during World War II. Design and development To provide the Bulgarian Air Force with a modern trainer, DAR took out a licence to build the Focke-Wulf Fw 44J. The first series, powered by a Siemens-Halske Sh 14 radial engine, was built at the DAR factory, but subsequent series were built at the DSF ('' Derzhavna Samoletna Fabrika'') Surviving aircraft in 1948 were re-engined with Walter Minor 6.III inline engines due to difficulty in procuring spares and the poor condition of the Siemens-Halske engines. DAR 9 production consisted of the series 1, which was built at the DAR factory and which carried the construction numbers 88 to 93 and Series 2 to Series 5, built at the DSF factory and which carried construction numbers 95 to 130. Operational history The DAR 9s were used for training at the Kazanlak Air School until at least 1949. Nine surplus DAR 9s were transferred to the Yugoslavian Air Force in 1947, withdrawn ...
