Tupolev '78'
The Tupolev '73', (''samolyot'' 73), was a Soviet trijet medium bomber of the late 1940s. It lost out to the Ilyushin Il-28 'Beagle'. Development The Tupolev OKB continued to develop the Tu-2 line with the advent of gas turbine power-plants. The Tu-8 ('69')was redesigned with two Rolls-Royce Nene I turbojet engines, replacing the piston engines in new nacelles. The new design was given the OKB designation '72' and official designation Tu-18 2 × Nene I, but was abandoned due to the more promising '73' design soaking up resources. Following the general arrangement of the Tu-2- Tu-8, '72', the initial '73' short-range bomber (official designation; Tu-20 2 × Nene I) had a shoulder mounted wing, a large unswept fin and rudder with integral dorsal fin, tri-cycle undercarriage and engines in long under-slung nacelles at about 1/3 span, which also housed the main undercarriage legs, when retracted. Before the design was finalised it was discovered that the Nene I engines were produci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium Bomber
A medium bomber is a military bomber Fixed-wing aircraft, aircraft designed to operate with medium-sized Aerial bomb, bombloads over medium Range (aeronautics), range distances; the name serves to distinguish this type from larger heavy bombers and smaller light bombers. Mediums generally carried about two tons of bombs, compared to light bombers that carried one ton, and heavies that carried four or more. The term was used prior to and during World War II, based on available parameters of Aircraft engine, engine and Aerospace engineering, aeronautical technology for bomber aircraft designs at that time. After the war, medium bombers were replaced in world air forces by more advanced and capable aircraft. History In the early 1930s many air forces were looking to modernize their existing bomber aircraft fleets, which frequently consisted of older biplanes. The new designs were typically twin-engined monoplanes, often of all-metal construction, and optimized for high enough pe ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), 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 (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1940s Soviet Bomber Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

Nudelman-Suranov NS-23
The NS-23 was a aircraft cannon designed by A. E. Nudelman, A. Suranov, G. Zhirnykh, V. Nemenov, S. Lunin, and M. Bundin during World War II as a replacement for the Volkov-Yartsev VYa-23 cannon. It entered service in 1944. The NS-23 round was derived from the 14.5×114mm anti-tank round by necking it out to 23 mm. A synchronized version, designated NS-23S (for ''synchronized''), was used for fixed installations firing through the propeller arc. Applications of the NS-23 included the Antonov An-2, Ilyushin Il-10, Ilyushin Il-22, Lavochkin La-9, La-15, MiG-9, Yak-9UT, Yak-15, Yak-17, Yak-23, and Tu-4. Some early MiG-15s were also equipped with the NS-23. The NS-23 was replaced in service by the Nudelman-Rikhter NR-23 The Nudelman-Richter NR-23 is a Soviet autocannon widely used in military aircraft of the Soviet Union and Warsaw Pact.

Tupolev '81T'
The Tupolev Tu-14 ( NATO reporting name: Bosun) (USAF/ DOD reporting name: Type 35), was a Soviet twinjet light bomber derived from the Tupolev Tu-73, the failed competitor to the Ilyushin Il-28 'Beagle'. It was used as a torpedo bomber by the mine-torpedo regiments of Soviet Naval Aviation between 1952–59 and exported to the People's Republic of China. Development The Tu-14 had its origin in the three-engined '73' design which used a pair of Rolls-Royce Nene turbojets under the wings and a single Rolls-Royce Derwent V in the tail, in an installation much like that of the central engine of a Boeing 727. The availability of the Klimov VK-1, a more-powerful version of the Nene, allowed the RD-500 to be deleted from the preliminary design, which was given the internal designation of "81". The other major change was the addition of a PSBN navigation radar which required a fifth crewmember to operate. This was rejected by the VVS and Tupolev reworked the design to eliminate t ...

Klimov VK-1
The Klimov VK-1 was the first Soviet jet engine to see significant production. It was developed by and first produced by the GAZ 116 works. Derived from the Rolls-Royce Nene, the engine was also built under licence in China as the Wopen WP-5. Design and development Immediately after World War II, the Soviet Union manufactured copies of first generation German Junkers 004 and BMW 003 engines, which were advanced designs with poor durability, limited by Germany's shortage of rare metals in wartime. However, in 1946, before the Cold War had really begun, the new British Labour government under the prime minister, Clement Attlee, keen to improve diplomatic relations with the Soviet Union, authorised Rolls-Royce to export 40 Rolls-Royce Nene centrifugal flow turbojet engines. In 1958 it was discovered during a visit to Beijing by Whitney Straight, then deputy chairman of Rolls-Royce, that this engine had been copied without license to power the MiG-15 'Fagot', first as the RD-45 ...

Tupolev Tu-8
The Tupolev Tu-8, OKB designation '69', was a long-range variant of the Soviet Tupolev Tu-2 medium bomber that first flew after the end of World War II. It was canceled when it proved to be unstable, structurally unsound and its generators were not strong enough to fully power its gun turrets. With the advent of jet-powered bombers, Soviet military planners decided that it simply was not worth devoting the necessary resources to fix its numerous problems. Development After the end of World War II the Tupolev OKB decided to continue its development of long-range variants of the Tu-2 which had begun with the unsuccessful Tu-2D during the war. Internally designated as the ANT-69, it was originally planned to use the new Shvetsov M-93 radial engines, but this was changed to the Shvetsov ASh-82M when the M-93 engine was delayed. It was to be armed with Berezin B-20 cannon on the existing mounts. The fuselage nose was completely revised in response to complaints by the VVS about the Tu ...
