Proto 2 (aircraft)
Proto 2 was a training biplane manufactured at the '' Fabrica de avioane Astra'' in Arad in 1924. Design and development Following the accident of Ioan Sava, a new variant of the Proto 1 was created, called the Proto 2. The airplane kept the original design, but as a safety measure, the structure of the wings was strengthened by increasing the section of the spars and adding another pair of interplane struts. Service After these improvements were made, the Astra Factory built 25 aircraft. The airplanes were then supplied to the Ministry of War, which assigned them to the Military Flying School of Tecuci Tecuci () is a municipiu, city in Galați County, Romania, in the historical region of Western Moldavia.

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] |
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 strut, 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 aeroplane, 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 impo ...

Aircraft First Flown In 1924
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 ...

V-8 Engine
A V8 engine is an eight-cylinder (engine), cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V engine, V configuration. The first V8 engine was produced by the French Antoinette_(manufacturer)#Private_engine-building_venture, Antoinette company in 1904, developed and used in cars and speedboats but primarily aircraft; while the American 1914–1935 ''Cadillac L-Head'' engine is considered the first road going V8 engine to be mass produced in significant quantities. The popularity of V8 engines in cars was greatly increased following the 1932 introduction of the Ford flathead V8 engine, ''Ford Flathead V8''. In the early 21st century, use of V8 engines in passenger vehicles declined as automobile manufacturers opted for more Fuel efficiency, fuel efficient, lower capacity engines, or Hybrid vehicle, hybrid and Electric vehicle, electric drivetrains.

Hispano-Suiza 8
The Hispano-Suiza 8 was a water-cooled V8 SOHC aero engine introduced by Hispano-Suiza in 1914, and was the most commonly used liquid-cooled engine in the aircraft of the Entente Powers during the First World War. The original Hispano-Suiza 8A was rated at and the later, larger displacement Hispano-Suiza 8F reached . Hispano-Suiza 8 engines and variants produced by Hispano-Suiza and other companies under licence were built in twenty-one factories in Spain, France, Britain, Italy, and the U.S. Derivatives of the engine were also used abroad to power numerous aircraft types and the engine can be considered as the ancestor of another successful engine by the same designer, the Hispano-Suiza 12Y (and Soviet Klimov V12 derivative aero-engines) which was in service during the Second World War. Design and development Origins At the beginning of World War I, the production lines of the Barcelona based Hispano-Suiza automobile and engine company were switched to the production of ...

Tecuci
Tecuci () is a city in GalaÈ›i County, Romania, in the historical region of Western Moldavia. It is situated among wooded hills, on the right bank of the Bârlad River, and at the junction of railways from GalaÈ›i, Bârlad, and MărășeÈ™ti. History The area neighboring Tecuci was the scene of a fierce battle in 1476 between Moldavian Prince Stephen the Great and the Ottomans. Under the Kingdom of Romania, it was the residence of the now-defunct Tecuci County. Economy The city was famous for its canned food factories, which preserve vegetables, fruit and meat, as well as for its mustard factories. Climate Climate in Tecuci is defined as Dfb (Humid continental climate with warm summers), bordering a Dfa (Humid continental climate with hot summers).

Spar (aeronautics)
In a fixed-wing aircraft, the spar is often the main structural member of the wing, running spanwise at right angles (or thereabouts depending on wing sweep) to the fuselage. The spar carries flight loads and the weight of the wings while on the ground. Other structural and forming members such as ribs may be attached to the spar or spars, with stressed skin construction also sharing the loads where it is used. There may be more than one spar in a wing or none at all. Where a single spar carries most of the force, it is known as the main spar. Spars are also used in other aircraft aerofoil surfaces such as the tailplane and fin and serve a similar function, although the loads transmitted may be different from those of a wing spar. Spar loads The wing spar provides the majority of the weight support and dynamic load integrity of cantilever monoplanes, often coupled with the strength of the wing 'D' box itself. Together, these two structural components collectively provide the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabrica De Avioane Astra
The Astra Aircraft Factory ( ro, Fabrica de avioane Astra) 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 machi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proto 1
Proto 1 was a training biplane designed by Major Ștefan Protopopescu in collaboration with Dumitru Baziliu and Gheorghe Ticău at Arsenalul Aeronautic in Bucharest in 1922. It was the first Romanian airplane to be built in a specialized enterprise. The first experimental flights were carried out by its designer, Ștefan Protopopescu, who held the Romanian pilot licence No.1. Production The Ministry of War ordered 25 aircraft on 10 January 1923 of this type from the ''Fabrica de avioane Astra''. The Astra Factory changed the wings on its own initiative, which reduced the strength of the wings, and during an early test flight, one of the wings broke and the aircraft crashed into the Mureș river, killing the test pilot. After the accident, production of Proto 1 aircraft was halted and improvements were made to the design, after which Astra manufactured a new variant as the Proto 2 Proto 2 is the name of the $55 million initiative of the Defense Advanced Research Projects Ag ...
