Mikulin AM-5
The Tumansky RD-9 (initially designated Mikulin AM-5) was an early Soviet turbojet engine, not based on pre-existing German or British designs. The AM-5, developed by scaling down the AM-3, was available in 1952 and completed testing in 1953; it produced thrust without afterburner. AM-5 engine is notable for making possible the first mass-produced supersonic interceptor, the MiG-19, and the first Soviet all-weather area interceptor, the Yak-25. When Sergei Tumansky replaced Alexander Mikulin as the OKB-24's chief designer in 1956, the engine was renamed RD-9. The engine was later built under license in China as the WP-6.

Yak-26
The Yakovlev Yak-26, OKB designation Yak-123, was a Soviet tactical supersonic bomber aircraft flown at the Tushino air show on 24 June 1956. The model did not enter service. Design and development The Yak-123-1 prototype was developed from the subsonic Yak-25, and in parallel with the Yak-27 aircraft family, with the main goal of operating at supersonic speed. Although the Yak-123 kept the Yak-25's layout, it had a more streamlined and longer fuselage with a glazed nose for a navigator-bombardier, replacing the Yak-25's radome. The engines were upgraded to the much more powerful RD-9AK afterburning turbojets and the wings modified. The Nudelman N-37 cannon was replaced with two NR-23 23 mm guns. The next prototype, designated Yak-26-3, had a tail barbette with two more such guns, but it was removed altogether after testing. An internal weapons bay was added for of bombs, including the nuclear RDS-4 ''Tatyana''. Additional bombs could be carried on underwing pylons. Engin ...

General Electric J47
The General Electric J47 turbojet (GE company designation TG-190) was developed by General Electric from its earlier J35. It first flew in May 1948. The J47 was the first axial-flow turbojet approved for commercial use in the United States. It was used in many types of aircraft, and more than 30,000 were manufactured before production ceased in 1956. It saw continued service in the US military until 1978. Packard built 3,025 of the engines under license. Design and development The J47 design used experience from the TG-180/J35 engine which was described by ''Flight'' magazine in 1948 as the most widely used American-conceived turbojet. Overhaul life for the J47 ranged from 15 hours (in 1948) to a theoretical 1,200 hours (625 achievable in practice) in 1956. For example, the J47-GE-23 was rated to run 225 hours time between overhauls. As installed on the F-86F, it experienced one in-flight shutdown every 33,000 hours in 1955 and 1956.

Allison J35
The General Electric/Allison J35 was the United States Air Force's first axial-flow (straight-through airflow) compressor jet engine. Originally developed by General Electric (GE company designation TG-180) in parallel with the Whittle-based centrifugal-flow J33, the J35 was a fairly simple turbojet, consisting of an eleven-stage axial-flow compressor and a single-stage turbine. With the afterburner, which most models carried, it produced a thrust of . Like the J33, the design of the J35 originated at General Electric, but major production was by the Allison Engine Company. Design and development While developing the T31 axial turboprop in 1943 General Electric realized that they had the resources to design an axial flow turbojet at the same time as their centrifugal-flow J33 engine. They recognized the axial would have more potential for the future and went ahead with the TG-180 engine. GE axial compressor designs were developed from the NACA 8-stage compressor. The e ...

Newton (unit)
The newton (symbol: N) is the unit of force in the International System of Units (SI). It is defined as 1 kg⋅m/s, the force which gives a mass of 1 kilogram an acceleration of 1 metre per second per second. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion. Definition A newton is defined as 1 kg⋅m/s (it is a derived unit which is defined in terms of the SI base units). One newton is therefore the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force. The units "metre per second squared" can be understood as measuring a rate of change in velocity per unit of time, i.e. an increase in velocity by 1 metre per second every second. In 1946, Conférence Générale des Poids et Mesures (CGPM) Resolution 2 standardized the unit of force in the MKS system of units to be the amount needed to accelerate 1 kilogram of mass at the rate ...

Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanchang J-12
The Nanchang J-12 (wikt:歼, Chinese: 歼-12) was a lightweight supersonic fighter aircraft, fighter built by the People's Republic of China, intended for use by the People's Liberation Army Air Force (PLAAF). It was one of the first serious attempts by Chinese aircraft manufacturers to develop an indigenous, modern jet propulsion, jet fighter. Weighing empty, the J-12 is one of the lightest jet fighters ever built. However, neither the J-12 nor the related Shenyang J-13 project entered service. Design and development In 1969, the PLAAF issued an order to build a small, inexpensive, STOL (short takeoff and landing) lightweight fighter in order to replace the MiG-19. Two designs were submitted, namely the Shenyang J-11 and the Nanchang J-12. Prototypes of the J-12 were designed by Lu Xiaopeng and built by the China Nanchang Aircraft Manufacturing Corporation, Nanchang Aircraft Manufacturing Company (NAMC). The J-12 was a small single-seat jet fighter with low-set, swept wings, sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanchang Q-5
The Nanchang Q-5 (; NATO reporting name: Fantan), also known as the A-5 in its export versions, is a Chinese-built single-seat, twin jet engine ground-attack aircraft based on the Shenyang J-6. The aircraft is primarily used for close air support. Design and development The PRC was an enthusiastic user of the MiG-19, which it manufactured locally as the Shenyang J-6 from 1958. In August 1958, the People's Liberation Army requested development of a jet attack aircraft for the air support role. Lu Xiaopeng was appointed chief designer of this project. Lu also designed the J-12 fighter jet. Although based on the MiG-19, the new design, designated Qiangjiji-5 (fifth attack aircraft design), had a longer fuselage, area ruled to reduce transonic drag and accommodate a 4 m (13-ft) long internal weapons bay. The air intakes were moved to the fuselage sides to make space in the nose for a planned target radar (which was never actually fitted). New wings with greater area and reduc ...

Shenyang J-6
The Shenyang J-6 (Chinese: 歼-6; designated F-6 for export versions; NATO reporting name: Farmer) is the Chinese-built version of the Soviet MiG-19 'Farmer' fighter aircraft, the world's first mass-produced supersonic aircraft. Design and development Although the MiG-19 had a comparatively short life in Soviet service, the Chinese came to value its agility, turning performance, and powerful cannon armament, and produced it for their own use between 1958 and 1981. While the basic Soviet-built MiG-19 has been retired from all nations, the Shenyang J-6 still flies for nine of its original 15 operators, however, in a very limited capacity. The J-6 airframe contributed to the Chinese ground attack version, the Q-5, which still flies for numerous nations. The J-6 was considered "disposable" and was intended to be operated for only 100 flight hours (or approximately 100 sorties) before being overhauled. The Pakistan Air Force was often able to extend this to 130 hours with dilig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ilyushin Il-40
The Ilyushin Il-40 (NATO reporting name: Brawny) was a two-seat Soviet jet-engined armored ground-attack aircraft. The first prototype flew in 1953 and was very successful except when it fired its guns, as their combustion gasses disturbed the airflow into the engines and caused them to flameout or hiccup. Remedying this problem took over a year and involved the radical change of moving the engine air intakes all the way to the very front of the aircraft and repositioning the guns from the tip of the nose to the bottom of the fuselage, just behind the nosewheel. The aircraft, now resembling a double-barreled shotgun from the front, was ordered into production in 1955. Only five production aircraft had been completed before the entire program was canceled in early 1956 when the VVS discarded its close air-support doctrine in favor of tactical nuclear weapons on the battlefield. Development Sergey Ilyushin had begun design studies during 1950–51 for a jet-engined ground-attack ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
