Jet de transporte Y-20 Diseño Chino - ( Su similitud sera copia del C-17?)

Mensaje por Rogersukoi27 el 13/7/2016, 7:02 pm

Si los Chinos han venido buscando con sinergias, obtener equipos de propulsion
para sus Transportes civiles y los militares, este diseño, que viene a consolidar su
Ala de fuerza aerea de transporte, ha equilibrado sus carencias de equipos de
fabricacion nacional, y podra proveer con menos tiempo y con capacidad de 200 tons.
por viaje a los lugares remotes, de avanzada o de respaldo en emergencias de catastrofes
segun se requiera.

La continuidad y el crecimiento claro de sus armas en todas sus especialidades, demuestra el crecimiento dinamico de sus proyectos, y la realidad que en menos de 5 años, la distancia entre China y Rusia y los E.U. sera minima.!!!

The Chinese air force has put its new home-grown heavy transport aircraft through its paces on its maiden flight.
The Y-20 officially entered military service on Wednesday in the southwestern province of Sichuan. The versatile plane has a maximum takeoff weight of around 200 tonnes, and is ideal for carrying cargo and personnel over long distances.
Describing the flight as a historical turning point, Wang Mingzhi, professor with the Air Force Command College, said the Y-20 is the first alternative for the Chinese Air Force to buying transport planes from abroad.
According to Deng Youming, head of Air Force test flight bureau and a test pilot himself, the Y-20 is highly responsive in the air and easy to maneuver.

Compared with older generation aircraft, the Y-20 has more automated systems, which mean both easier operations and higher requirements of pilots, Deng added.
The Air Force has introduced civil aviation flight-training patterns in training Y-20 pilots, and has established a specialist training school for test pilots.

Designed and manufactured by the state-owned Aviation Industry Corporation of China (AVIC), the Y-20 made its first test flight in January 2013 after five years of development. After years of test flights, the first two Y-20s were delivered to the Air Force last month.

Key to the building of a strategic air force for China, fleets of Y-20 freighters are expected to greatly improve the air force's rapid nonstop reach capability across both theater commands and continents, said Wang.
"It will help the country actively participate in international cooperation, peacekeeping missions and humanitarian missions," Wang added.

Aside from its military function, the developers expect a substantial commercial market for the Y-20 and its variants.
"With advanced technology and forward-looking design, the Y-20 has great potential and advantages for further development," said Zhu Qian, head of AVIC's Large Aircraft Development Office.

For instance, a civilian version of the Y-20 is expected to be used in China's booming logistics and express delivery industries, Zhu added.
"The successful maiden flight of the Y-20 is a new beginning after a long, hard journey for China's aviation industry," said Zhu.

OPINION TECNICA SOBRE LOS MOTORES DE PROPULSION DE ORIGEN RUSO FABRICADOS POR  AVIADVIGATEL,
su desempeño tiene reservas aparentes por tener errores pequeños en su diseño!!!!


Robert M. Farley, an assistant professor at the University of Kentucky’s Patterson School of Diplomacy and International Commerce, said engine designs had hindered Chinese aerospace ambitions. The Xian Aircraft Industry Y-20, a domestically produced military transport that will also be shown at Zhuhai, has been developed with engines made by the Russian company Aviadvigatel that are far less efficient than their Western counterparts, typically made by General Electric, Pratt & Whitney or Rolls-Royce.

“The problem with Chinese engines is that they’ve been remarkably unreliable,” Mr. Farley said. “Engines require extremely tight tolerances in construction; even small errors can lead to the engine burning out.”

No creo que sea una copia del C-17 por que es poco mas pequeño y con esto tiene una menor capacidad de carga, por lo que tal vez de un parecido pero no sea del todo una copia del mismo.

La parte tecnica que ANTONOV ha tenido con sus contribuciones, son la comparacion
tecnica de sus naves de alto calado, con sus motores de propulsion capaces de generar
48-50 tons libres de carga, y siendo asi, les propusieron versiones del ANTONOV 70,mas
los chinos se pusieron muy requisitosos, y Antonov tuvo que mover sus diseños
con 4 motores de bypass, y les hicieron mas accesible los requerimientos chinos en
su diseño de vanguardia.
Si los Ucranianos se hubieran puesto las pilas, les hubieran mejorado en tiempo
lo que los Chinos lograron con mas objetividad y velocidad de respuesta.
 Ahora los Ruskis y Ucranianos, seguramente aprenderan en algo las ideas que
los mismos chinos no pensarian hace 10 años e poder logarlo.
La opinion del Gabacho sobre la calidad rusa de sus motores, ha sido probada con
los AN-77 al igual que los IL-76 MD tienen lo propio. Con equipos rusos ya probados,
las opiniones salen sobrando.  A buen entendedor, pocas palabras!!!!!




Y-20 / Y-XX - Antonov Participation

In June 2000 it was reported that Russia and Ukraine would build the new-generation Antonov 70 transport aircraft, not with Germany, as had been planned, but with China. Russian Defense Minister Igor Sergeyev said that negotiations with Berlin had resulted in the Germans saying they would not support the joint Ukrainian-Russian An-70 project, Interfax reported. ``We won't try to win over the Germans, but will complete the project with China," Sergeyev said. A Chinese military delegation visited Ukraine and expressed an interest in the AN-70 transport aircraft.

At the Zhuhai airshow in November 2000, Antonow tried to market the An-70 in China. This would likely involve co-production with AVIC II. The Antonov Design Bureau offered cooperation to the Shansiy aircraft building corporation to build a new airplane using Antonov An-70 as a basic model. The Chinese side left the offer unanswered, although the proposition was negotiated during Li Peng's visit to Ukraine in the middle of 2000.

In 2003, a publication by Hu Xiaofeng [the general manager of Shaanfei - Shaanxi Aircraft Corporation] proposed using the An-70, a Ukrainian heavy transportation aircraft model still in its testing stage, as China’s model for its large transportation aircraft. Shaanfei’s Y-8 middle-size transportation aircraft, another Antonov knock-off, had been the only domestically made transportation aircraft used by the PLAAF.

At the 2008 Zhuhai airshow, Antonov displayed a model of the large An-70 military transport aircraft, based on which China and Ukraine could jointly develop the AN-70-600. The new An-70-600 transport aircraft's maximum payload was expected be 48t-50t compared to An-70's 47t. One of China's requirements is that An-70-600's flight range should be at least 3,200km when carrying the maximum load. China also hoped that it can carry at least 3 China-made infantry fighting vehicles, or 120-150 paratroopers.

According to Ukrainian reports, at least three design candidates were submitted to the Chinese to address the Y-20 requirements:

An-70 turboprop
An-77, a version of the An-70 with turbofans
An-170, a heavily modified and larger version of the An-70

According to Ukrainian sources, the Antonov bureau proposed a radical development of its An-70 transport that would replace its current contra-rotating propfan engines with four turbofan engines, lengthen the fuselage and increase cargo capacity to between 50 and 60 tons. This would approach the 70-ton capacity of the Boeing C-17 and exceed the 50-ton capability of the Ilyushin Il-76MD. The Chinese military transport aircraft would adopt different design concepts and technologies than the An-70 transport aircraft designed by Ukraine and Russia, and will be powered by four jet engines.

It appeared the new An-70 variant may be able to carry four of the ZLC-2000 airborne tank revealed in 2005 by the PLA. In September 2005 the PLA agreed to purchase about 32 Il-76MD transports, which can carry three ZLC-2000s, in addition to about 20 acquired during the 1990s. Antonov has also helped China's Shaanxi Aircraft Company to produce a much improved version of the Y-8 called the Y-9, which can carry 20 tons of cargo. In addition, China held discussions with Antonov regarding the possible co-production of the 150-ton capacity An-124 Ruslan, which exceeds the 120-ton capacity of the US C-5 transport.

By early 2007 ANTK Antonov set up a new VTL (Heavy Transport Aircraft) working group, to start developing a heavy transport using the existing designs for the An-77, a turbojet version of the An-70, which had earlier been put on hold. The take-off weight of the aircraft was increased from 132 tonnes to 187 tonnes, the maximum payload went up from 47 to 50 tonnes, and the volume of the cargo bay was increased by adding a 2-meter insert in the airframe in front of the center-wing section. The original An-77 design relied on four CFM56-5A16 bypass turbofan engines; these were replaced by four D-30KP-2 bypass turbofan engines eventually used in the Y-20. The aircraft retained the ability to take-off and land using short landing strips, although the take-off length went up to 900m. The solution for increasing the thrust was the same as used in the An-77. First introduced in the C-17A Globemaster III, it directs the exhaust jet of the bypass turbofan engine at the high-lift flaps.

Major changes were made to the Y-20 design in 2010, with the entry into service with the Chinese army of the Type 99-IIA [aka Type 99A2] main battle tank. The combat weight of this tank, which has many similarities to German Leopard IIA6, is 58 tonnes. This imposed greater payload requirements for the aircraft, which was still expected to be able to carry the heaviest tanks in service with the Chinese Army. The project switched to a different variant of the An-70, the An-170. Antonov worked on the An-170 is a heavy operational-strategic transport in the late 1980s and early 1990s. The project was in competition with the the Ilyushin Bureau's Il-106, which was announced the winner by the Soviet authorities. Owing to the crisis after the break-up of the Soviet Union, neither aircraft entered production. The An-170 is much larger and heavier than the An-70, with a take-off weight of 230 tonnes and a maximum payload of 60 tonnes. Another difference is the regular wing profile of the An-170, whereas the An-70 uses the so-called supercritical profile.

Richard D. Fisher, Jr., Senior Fellow, International Assessment and Strategy Center, in Testimony for the U.S.-China Economic and Security Review Commission Hearing on China's Emergent Military Aerospace and Commercial Aviation Capabilities, May 20, 2010, noted that "This decade will ... see the emergence of a new C-17 size Chinese strategic transport aircraft.... it can be expected that during this year or next that AVIC will reveal more details on this large transport. In 2006 Ukrainian officials noted they had been hired as consultants by X'ian Aircraft Design and Research Institute (603 Institute) to consult on large aircraft programs, to include the possible adaptation of Antonov's turbofan-powered An-70 for turbofan propulsion. Then in 2007 a Ukrainian official confirmed that images of a model of a Chinese four-turbofan military transport was another AVIC-1 design."

China Set to Show Off J-31 Stealth Fighter, Y-20 Heavy Transport Aircraft Later This Year


Beijing will tout its two indigenous military aviation platforms at the 2016 Zhuhai airshow.

By Ankit Panda
September 13, 2016







China is set to show off its J-31 advanced stealth fighter and Y-20 heavy transport aircraft later this year at a trade show. According to Xinhua, China’s state-owned news agency, the Aviation Industry Corp. (AVIC) of China, a major state-owned defense aviation enterprise, will feature the two aircraft prominently at the upcoming 11th China International Aviation and Aerospace Exhibition in the southern city of Zhuhai, in Guangdong province. The show will open on November 1.
The two aircraft are built by AVIC subsidiaries; the J-31 (also known as the “Gyrfalcon”) is built by Shenyang Aircraft Corporation and the Y-20 (codenamed the Kunpeng and nicknamed “Chubby Girl”) by Xian Aircraft Industrial Corporation. The Y-20 was introduced into service with China’s People’s Liberation Army-Air Force (PLAAF) earlier this summer while the J-31 is set to enter service with the PLAAF in roughly two to three years by most independent estimates.
Both aircraft fulfill drastically different strategic roles for the PLAAF. The Y-20 will abet Chinese expeditionary military operations with heavy transport and strategic airlift duties, much like the U.S. and the J-31 serving an agile multirole function, much like the U.S. C-117 Globemaster and Soviet Antonov An-70. F-35 Lightning Joint Strike Fighter. Indeed, the design of the J-31 is believed to have been the product of industrial espionage of the F-35. The two aircraft share common hardware elements, including a similar airframe design and two internal weapons bays. Though much the aircraft’s detailed specifications remain publicly unknown, aviation experts estimate that the J-31 features inferior avionics to the F-35.

The Zhuhai show later this year will be far from the first time AVIC has promoted the J-31. As my colleagueFranz-Stefan Gady reported last year, AVIC promoted the aircraft for the first time overseas at the Dubai Air Show in the United Arab Emirates. Moreover, AVIC promoted the J-31 at the Zhuhai airshow in 2014, kicking off a spate of speculation that Beijing was interested in offering the aircraft as an export model–a low-cost F-35 competitor of sorts for states with tighter budgets and less geopolitical amity with the United States. (The Chengdu J-20, meanwhile, much like the U.S. F-22 Raptor, is restricted for PLAAF use exclusively and barred for export.)
