duke7 escribió:China wants to buy Ukraine's An-70 military air transportHONG KONG, Dec. 2 (UPI) -- Ukraine and China have been engaged in negotiations on the joint design of a large military transport aircraft, according to sources in Ukraine's Antonov Aircraft Co. The agreement was expected to be signed this month, with the aircraft project to begin soon afterward.
According to a source in the Ukrainian military industry, the basic design concept of the aircraft already has been finalized. The Chinese military transport aircraft will adopt different design concepts and technologies than the Antonov An-70 transport aircraft designed by the former Soviet republic of Ukraine and the Russian Federation, the source said, and will be powered by four jet engines. Additional technical details of the transport aircraft are to be finalized after the signing.
In recent years the People's Republic of China has greatly reinforced its strategic military ties with Ukraine in a variety of areas, but this is the two countries' first collaboration in developing a large aircraft. A source from the Russian aviation industry told United Press International that China did not ask for Russian assistance on this project, suggesting that China is shifting its design cooperation away from Russia and toward Ukraine. It also indicates that the new aircraft will be an upgrade of the Antonov An-70 air transport rather than a duplication of it.
China expressed keen interest in the Antonov An-70 air transport as early as the mid-1990s, when the aircraft was undergoing flight tests in Russia and Ukraine. The aircraft did not get off to an auspicious start, however. The first Antonov An-70 prototype was tested in Kiev, Ukraine, in December 1994, but the same plane crashed the following year. The second prototype was damaged in an accident at Omsk, Russia, in 2001.
In 2002 Russia and Ukraine agreed to each take a 50-percent stake in the project, and two more prototypes were manufactured. But by April 2006, following the Orange Revolution in Ukraine, Russia decided to withdraw from the project.
The Antonov An-70 air transport is still being tested. The Ukrainian air force appears to be the only buyer, having announced its intent to procure five of the An-70 aircraft. China's decision to design its own large military transport aircraft on the foundation of the Antonov An-70 technologies is apparently intended to take advantage of the extensive testing the aircraft already has undergone, to save research and development time.
The Antonov company source has confirmed the Chinese military transport aircraft will not be fitted with the Antonov An-70's D-27 engine, though it did not disclose what type of engine will be used. The D-27 engine has an output thrust power of 14,000 horsepower, maximum payload of 47 tons and a flight range of 4,050 miles with a payload of 20 tons.
China recently imported 240 D-30 KP-2 engines from Russia to use in upgrading its own, home-produced H-6K bombers. It is unlikely that this engine would be used for the military transport plane, however. Russia is already replacing some of the D-30 KP-2 engines on its Ilyushin Il-76 air-lifter with upgraded D-30 KP-3 or PS-90 engines. The D-30 KP-2 does not meet Europe's latest noise control standards, so the Ilyushin Il-76 military air transport powered by these engines are not allowed to land at European airports.
Hay que recordar que Rusia no a abandonado el proyecto del AN-70, ah invertido cerca del 60% del presupuesto del proyecto, China quiere crear su propia versión del AN-70 pero con asistencia ucraniana; existe un join venture entre Rusia e India para crear el Il-214 pero entraia a competir en la categoría del C-130, en cambio el AN-70 compite con el Airbus A400M.

Rusia retrasa hasta el año 2011 la entrega a China de 34 aviones de transporte militar Iliushin-76 y cuatro aviones nodriza Iliushin-78, dio a entender hoy Mijaíl Dmítriev, jefe de la agencia rusa para cooperación militar técnica (FSVTS).
El importe del respectivo contrato, suscrito en septiembre de 2005, asciende a 1,5 mil millones de dólares. En el pasado, ambos modelos se fabricaban en la planta aeronáutica de Taskent, en Uzbekistán, pero luego se decidió trasladar la producción a la ciudad rusa de Uliánovsk, para lo cual es necesario instalar allí una nueva línea tecnológica evaluada en torno a 100 millones de dólares.
"A día de hoy no tenemos aviones listos y esperamos una señal desde la planta de Uliánovsk para proceder a la ejecución del contrato", dijo Dmítriev al agregar que "a China todavía le interesan estas máquinas".
Según los datos de que dispone RIA Novosti, la fábrica de Uliánovsk será capaz de iniciar la producción de los Iliushin-76 e Iliushin-78 hacia diciembre de 2010.
El Iliushin-76 es el primer modelo de propulsión a chorro que la industria aeronáutica rusa empezó a producir en serie para el transporte de cargas, a mediados de la década del 70. Las características del avión le permiten aterrizar en pistas cortas, de 450 metros, y transportar cargas de hasta 50 toneladas o 225 pasajeros. También es capaz de realizar el desembarco de 126 paracaidistas y equipos militares que pesan hasta 21 toneladas. Hasta la fecha, Rusia exportó 900 aviones Iliushin-76, en particular, a India, Iraq, Irán, Libia y Siria.
El Iliushin-78 es un avión nodriza hecho a partir del Iliushin-76.

Fighter: Improved Version First Flight in China
(NSI News Source Info) Chengdu - December 31, 2008: Several eyewitnesses in Chengdu city prove that a greatly improved J-10 fighter makes its first flight from CAC (Chengdu Aircraft Corporation) internal airport in Huang Tianba.
Some spectators say that the eyeable improvements include a DSI inlet, Forward Looking Infra Red (FLIR) Pod and Tail Wing-tip Integrated Electrical Avionics. Besides, some Internet resources claim that new J-10 has equipped with high-performance AESA radar, modified wing inner structure and stealth in-board pylons. The engine is still the Russian AL-31F, which will be replaced by FADEC AL-31FM3 for better air performance. But China’s WS-10 engine also has opportunity.
The flight lasts about 10 minutes and the test pilot is believed to be Liang Wanjun (梁万俊).
Although closing to 3.5th+ generation fighters like Typhoon and Rafael, how many new J-10 fighters will be purchansed by PLA Air Force is still one question, because CAC and SAC have entered the drastic competition for PLA’s 5th generation fighter. There always a rumar that CAC will provide prototype fighter before 2012
