Wind Tunnel
Wind tunnels are large tubes with air blowing through them which are used to replicate the interaction between air and an object flying through the air or moving along the ground. Researchers use wind tunnels to learn more about how an aircraft will fly. NASA uses wind tunnels to test scale models of aircraft and spacecraft. Some wind tunnels are large enough to contain full-size versions of vehicles. The wind tunnel moves air around an object, making it seem as if the object is flying. Most of the time, large powerful fans suck air through the tube. The object being tested is held securely inside the tunnel so that it remains stationary. The object can be an aerodynamic test object such as a cylinder or an airfoil, an individual component, a small model of the vehicle, or a full-sized vehicle. The air moving around the stationary object shows what would happen if the object was moving through the air. The motion of the air can be studied in different ways; smoke or dye can be ...

Prime Minister Of Romania
The prime minister of Romania ( ro, Prim-ministrul României), officially the prime minister of the Government of Romania ( ro, Prim-ministrul Guvernului României, link=no), is the head of the Government of Romania. Initially, the office was styled ''President of the Council of Ministers'' ( ro, Președintele Consiliului de Miniștri, link=no), when the term "Government" included more than the Cabinet, and the Cabinet was called the ''Council of Ministers'' ( ro, Consiliul de Miniștri). The title was officially changed to ''Prime Minister'' by the 1965 Constitution of Romania during the communist regime. The current prime minister is Nicolae Ciucă of the National Liberal Party (PNL), who has been serving since November 2021 onwards as the head of government of the National Coalition for Romania (CNR). Nomination One of the roles of the president of the republic is to designate a candidate for the office of prime minister. The president must consult with the party that ...

IAR 80
The IAR 80 was a Romanian World War II low-wing monoplane, all-metal monocoque fighter and ground-attack aircraft. When it first flew, in 1939, it was comparable to contemporary designs being deployed by the airforces of the most advanced military powers such as the Hawker Hurricane and Bf 109E. Production problems and lack of available armament delayed entry of the IAR 80 into service until 1941. It remained in frontline use until May 1945. Development In order to ensure that the Royal Romanian Air Force (''ARR'') could continue to be supplied with aircraft in time of war, the government subsidized the creation of three major aircraft manufacturers in the 1920s and 1930s. The first was Societatea pentru Exploatări Tehnice (SET) which was formed in Bucharest in 1923. Next came Industria Aeronautică Română (IAR) which set up shop in Brașov in 1925. Finally there was Întreprinderea de Construcții Aeronautice Românești (ICAR), which was founded in Bucharest in 1932. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IAR 15
The IAR 15 was a low-wing monoplane fighter designed in Romania in 1933. The IAR 15 was designed by Elie Carafoli for the Romanian Air Force. It was a lightly armed low-wing cantilever monoplane with a radial engine, fixed undercarriage and open cockpit. Development The sustained efforts of Elie Carafoli and his team paid dividends when the first order for IAR 14 was finally placed. With production started and a small profit secured, Dipl.-Eng. Carafoli decided to try something new. The result was the I.A.R. 15. The inline engine was abandoned and instead a radial powerplant was substituted. Accordingly, the front fuselage underwent a major redesign. The cross-section was rounded and an NACA ring covered the 600 h.p. (447 kW) Gnome & Rhône 9Krse engine. With the new nine-cylinder radial the aircraft attained a top speed of 375 km/h at 4,000 m and could climb to 5,000 m in 8 minutes. The ceiling was raised to 10,500 m and an endurance of 600 km was possible. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IAR 14
The IAR 14 is a Romanian low-wing monoplane fighter-trainer aircraft designed before World War II. Design and development After rejection of IAR 12, Romanian officials did not want to discourage eventual national aircraft production. Therefore, in early 1933, an unofficial message was forwarded from top levels to Brasov, essentially indicating that a small number of fighter-trainers would be purchased by the air force. The I.A.R. team immediately began to work on a new type, designated I.A.R. 14, still based on the experience gained with previous designs The airplane was designed by IAR design bureau in 1933 and was an evolution from the IAR 12 prototype. It was a cantilever low-winged monoplane with a spatted main undercarriage with V-form legs and a single, open cockpit over the wing. The rectangular section fuselage was of mixed metal-wood configuration, with the front half covered by duralumin sheets and the rear part with pine plywood. The tail had been modified once ...

Flight Airspeed Record
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), which also ratifies any claims. Speed records are divided into multiple classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibians; then within these classes, there are records for aircraft in a number of weight categories. There are still further subdivisions for piston-engined, turbojet, turboprop, and rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads. Timeline indicates unofficial records, including unconfirmed or unpublicized war secrets. Official records versus unofficial The Lockheed SR-71 Blackbird holds the official Air Speed Record for a manned airbreathing jet engine aircraft with a speed of . The reco ...

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoplane
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 a ...

IAR CV-11
The IAR CV 11 was a Romanian fighter prototype in 1930, designed by Elie Carafoli, and it was IAR's first original aircraft. Development In early 1930 a contest was called by the ARR for a new fighter type to equip its squadrons. During July and October, seven foreign types were tested at an airfield near Bucharest. No decision was made, however, since none of the contenders reached the minimal speed limit set by the requirements at . Despite the inconclusive results, the favourite plane seemed to be the chunky-looking Polish P.Z.L. P.1/II prototype, registered SP-ADO. During the same period, the air force commission was informed that a new fighter prototype had been completed at I.A.R., and it had reached an impressive top speed during initial test flights. Built according to the plans of Dipl.-Eng. Dr. Elie Carafoli and Lucien Virmoux, the I.A.R. fighter was an advanced construction. Named the C.V. 11 after its designers, it had a mixed metal-wood structure and cantilever, l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blériot Aéronautique
Blériot Aéronautique was a French aircraft manufacturer founded by Louis Blériot. It also made a few motorcycles between 1921 and 1922 and cyclecars during the 1920s. Background Louis Blériot was an engineer who had developed the first practical headlamp for cars and had established a successful business marketing them. In 1901 he had built a small unmanned ornithopter, but his serious involvement with aviation began in April 1905 when he witnessed Gabriel Voisin's first experiments with a floatplane glider towed behind a motorboat on the river Seine. A brief partnership with Voisin followed, but after the failure of the Blériot III and its modified version, the Blériot IV, the partnership was dissolved and Blériot set up his own company, "Recherches Aéronautique Louis Blériot" (Louis Blériot Aeronautical Research) at Courbevoie in March 1909.
