Tungsten Military -China successfully lands first fighter jet on aircraft carrier

News Colletted By Chinatungsten Online
The state-run Chinese press on Sunday announced the success of the first takeoff and landing of a fighter jet on the aircraft carrier Liaoning, the first and only such vessel in the Chinese navy.
The first images of the new model J-15 fighter on board the Liaoning, which was commissioned earlier this year, were shown by China Network Television, the Internet channel of the state-run CCTV network.
The J-15 is the first Chinese multi-use fighter designed to be flown from aircraft carriers, according to the daily Global Times, which is usually the first Chinese media outlet to report the country's military advances.
Experts compare the technology used in the J-15 with that of the U.S. F-18 or the Russian SU-33.
The Liaoning was officially launched by the Chinese navy on Sept. 25 after a 10-year remodeling of the old Soviet vessel Varyag, which China bought from Ukraine 13 years ago.
The first tests of the new flagship vessel of the Chinese navy come at a time of maritime tension between China and its neighbors - Japan, Vietnam and The Philippines - over disputes regarding the sovereignty of several archipelagos in East Asia: the Spratly Islands, the Paracel Islands and Diaoyu/Senkaku.
Until the commissioning of the Liaoning, the Asian giant was the only permanent member of the U.N. Security Council not to have at least one aircraft carrier in its fleet.

Tungsten Military -China now capable of deploying jets on aircraft carrier: Navy



BEIJING: China is now capable of deploying fighter jets on its first aircraft carrier after successful landing exercises on it, a senior navy officer has said.

China successfully landed and took off the J-15 jet from 'The Liaoning' aircraft carrier yesterday. Pilots have mastered key skills to ensure the success of the take-off and the landing, especially under unfavourable conditions such as poor visibility and unstable airflow, Vice-Admiral Zhang Yongyi, a deputy commander of the Chinese People's Liberation Army (PLA) Navy, has said.

"It's like 'dancing on a knifepoint' as the aircraft have to land on a very limited space," Zhang was quoted by state-run Xinhua news agency as saying, while commenting on the successful flight landing recently conducted on 'The Liaoning'.

The aircraft must land precisely over a very short and narrow runway on the carrier at a speed of several hundred kmph, Zhang said, after the J-15 fighter succeeded in the landing tests.

"We have done all these test flights from the very beginning, and finally we mastered the key skills for the landing of carrier-borne aircraft," Zhang, who is also the commander-in-chief in charge of the tests and training programme of the flight landing, said.

Currently, the Chinese pilots have found out the right ways to conduct the landing and they have consolidated their skills, according to the Navy officer, who himself is a meritorious pilot of the Chinese naval air force.

Zhang said the carrier-borne aircraft and special equipment for the landing flight have gone through strict tests, and fighter jets can be deployed on the aircraft carrier.

Tungsten Military -Gaming China's naval rise




With news that a navy jet has just been landed successfully for the first time on China’s new aircraft carrier, China’s naval rise has once again been brought to the fore. What does a growing Chinese naval capacity mean for the future?

A strategic analysis group, Wikistrat, which describes itself as ‘the world's first massively multiplayer online consultancy”, recently ran a crowd-sourced simulation called “When China’s Carrier Enters the Persian Gulf”. For the simulation four possible ‘pathways’ were mapped based on different projections of geopolitical developments. Some of the conclusions drawn include:
“It is quite possible that, when the day finally arrives and China’s carrier enters the Persian Gulf, it will matter far more to India than to America.
Plenty of experts within the U.S. national security community see good reason to encourage China and the PLAN toward blue-water capabilities, believing that path will exhaust Chinese military spending and push the Chinese people to question devoting so many resources to distant responsibilities. Imperial overstretch works the same everywhere.
The most clever Chinese policy option would be to multilateralize any naval extension it makes in the direction of the Persian Gulf. China’s growing dependence on the region is matched by that of East Asia as a whole.”
According to the consultancy group, this scenario could feasibly play out between 2025-2030. The full report is available here.

Tungsten Military -Top attack aircraft – T-50 to J20




NewsCollettedBy Chinatungsten Online
Jet fighter attack aircraft are essential components of modern warfare, and recent unveilings back this up. Anthony Beachey examines the top attack aircraft available today, including Russia's T-50, China's secretive J20, the US F22 Raptor and Europe's EADS Eurofighter. 

Tens of billions of dollars-worth of contracts are at stake in the coming years as the world's top manufacturers seek to win orders for the next generation of fighter aircraft. India, for example, is in the final stages of selecting the plane for a $10.4bn contract.
The four-year-long selection process that began in August 2007 will reach its conclusion when Indian officials open the tender from the manufacturers - the European Aeronautic Defence and Space Company (EADS) and Dassault of France. India had previously considered bids from Lockheed Martin's F-16, Boeing's F/A-18, Russian United Aircraft Corporation's MiG-35 and Swedish SAAB's Gripen.

India's jet fighter plans - T-50 or F 35?

India has already signed a deal with Russia for the joint development of a fifth generation fighter aircraft or FGFA, based on the Sukhoi T-50 plane design.
According to a report from the Russian RIA Novosti news agency, published in late October, the T-50 fifth generation fighter will be ready to take to the skies in the near future. The T-50 made its maiden voyage in January and two prototypes have since been undergoing flight tests.
The plane, developed under the PAK FA (future aviation system for tactical air force) programme at the Sukhoi OKB, is the first new major Russian-designed warplane since the fall of the USSR. It is expected to enter service in 2016.
Unsurprisingly however, the US continues to pursue the Indian market, given that New Delhi plans to spend more than $35bn on at least 166 single-seat and 48 twin-seat 5th-Gen fighters from 2020 onwards.
Washington is pushing Lockheed Martin's F-35 fifth generation fighter. However, delays and cost overruns have plagued the F-35 Joint Strike Fighter - which at $238bn is the Pentagon's biggest weapons procurement programme - and one variant of the plane suffered cracks in the bulkhead after it had flown just 1,500 hours out of a planned 16,000.

The F-22 of the US Air Force

The US Air Force has also had to ground dozens of F-22 fighter jets for the second time this year, after a pilot had experienced oxygen deficiency in the cockpit, officers reported in early October. The announcement follows the air force's highly unusual step of grounding the entire Raptor fleet between May and mid-September, to allow engineers to investigate possible problems with the plane's oxygen supply.
Elaborate tests and safety measures have nevertheless failed to locate the precise source of the fault. The latest case follows around a dozen previous incidents affecting F-22 pilots over a three-year period, the circumstances of which the US Air Force is reluctant to discuss in detail.
At a cost of nearly $150 million a plane, the F-22 Raptor is designed mainly for dogfights against rival fighter jets, and the radar-evading aircraft were not deployed in the Nato-led campaign over Libya. The US Air Force has more than 160 F-22 Raptors and plans to construct a total of 187.
US legislators and defence contractors lobbied for years to fund a larger F-22 fleet. However, former defence secretary Robert Gates managed to defeat this initiative, arguing against an urgent need to raise numbers of the sophisticated aircraft.

China steps-up J-20 stealth fighter development

China, the rival Asian superpower to India, has meanwhile been busy upgrading its military, developing the J-20 stealth fighter that reportedly will be equipped with the radar-evading capability of fifth-generation fighters such as the F-22 and F-35. China began testing the plane in January 2011. However, some analysts argue the threat posed by the J-20 is greatly exaggerated and that it incorporates obsolete technology.
As a guide, Richard Aboulafia, Vice President of Analysis at Teal Group, told Aerospace Technology that he gauges the capabilities of the modern, combat aircraft according to the following criteria:
• Access to off-board space, ground and air-based sensors, particularly a capable AEW/AWACS system with a well-trained crew and robust data links.
• Effective sensor fusion to allow the pilot to utilise this information, as well as data from onboard sensors.
• An integrated EW system.
• An AESA radar with a high level of reliability.
• High-quality theoretical and practical training to ensure effective use of resultant data and equipment.
• Pilot training to include plenty of flight hours.
• Powerful engines, ideally capable of supercruise, with a high mean time between overhaul and failures.
• An airframe with low-observable characteristics.
• A robust air-to-air refuelling capability encompassing equipment, readiness and training.
• Sophisticated and reliable, precision-guided weaponry.
• A robust hardware and software upgrade programme, to maintain the plane's effectiveness over the next five, 10 and 30 years.
• Maintenance procedures to keep the plane operating with a high, mission-capable rate.
• Equipment designed to facilitate maintenance and allow easy access to electronic diagnostic tools, and ideally a sophisticated health-usage monitoring system (HUMS).
According to Aboulafia, the J-20 incorporates just one item from this list (number seven). He is "not convinced that the People's Liberation Army Air Force (PLAAF) features any other items from the list, although China seems to be making some progress in terms of item no 9".

Reduced budgets mean reduced demands for the EADS Eurofighter

Different problems, notably the Eurozone's economic crisis, are besetting the EADS Eurofighter. As part of an austerity drive, Germany plans to slash the number of military aircraft it will buy from EADS, the European aerospace company, in a bid to reduce its armed forces by one-fifth. Berlin now wishes to purchase 40 instead of 177 Eurofighters.
The UK in turn began reducing orders for Eurofighter Typhoon fighter jets three years ago. In the spring of 2009, London secured a deal that allowed it to sell on part of its Typhoon contingent to Saudi Arabia.
A similar plan is being considered for the aircraft Germany had contracted to buy but now considers surplus to requirements. The availability of buyers is far from certain, according to industry experts.
The Eurozone's economic difficulties, as well as the problems besetting the US's F-35 Joint Strike Fighter and the F22 Raptor, could accelerate the emergence of China and Russia as potential rivals in the jet fighter attack aircraft stakes. However, doubts remain as to whether either or indeed both countries have the advanced technology capable of competing with the Western world.

Tungsten Military -China flexes military muscle with J-31 stealth jet



NewsCollettedBy Chinatungsten Online


China’s second stealth fighter jet that was unveiled this week is part of a programme to transform China into the top regional military power, an expert on Asian security said on Friday.
The fighter, the J-31, made its maiden flight on Wednesday in the northeast province of Liaoning at a facility of the Shenyang Aircraft Corp which built it, according to Chinese media.
“This is the second entirely new fighter design that’s emerged from China in the last two years, which suggests a pretty impressive level of technical development, and puts them ahead, certainly, of all their regional neighbours,” said Sam Roggeveen, a security expert with the Lowy Institute in Sydney.
The Chinese military “has been extremely deliberate and well funded and persistent, and it’s starting to bear fruit”, Roggeveen said.
“What you’re now seeing since the early ‘90s is the slow emergence of a first-class regional military power.”
China’s defence ministry did not respond to a request for comment.
China’s previous stealth fighter, the J-20, is a heavier aircraft and believed to be less manoeuvrable than the J-31.
China’s military capabilities lag far behind those of the United States, but China is seeking aggressively to boost its strength, including launching its first aircraft carrier — purchased from Ukraine — in September.
The buildup is a worry for neighbours uneasy about China flexing its military muscle, especially in territorial disputes with Japan in the East China Sea and with Vietnam and the Philippines in the South China Sea.
“Just like the US F-22 and F-35 fifth-generation fighters, the J-20 and J-31 will complement each other during future operations,” Bai Wei, former deputy editor of the weekly Aviation World, told the Global Times newspaper.
“The J-31 is almost certainly designed with the intention to have the potential of operating on aircraft carriers, judging from its enhanced double-wheel nose landing gear and two big tail wings, which help increase vertical stability,” Bai said.
China needs both the heavier J-20 and more nimble J-31 to defend its air space, Bai said.
The J-31 is a mid-sized fighter using Russian-made engines which will later be replaced by Chinese engines, the Global Times reported.
“The big Achilles heel for Chinese aerospace generally, and particularly for both of these two programmes, is engines,” Roggeveen, a former analyst for Australian government intelligence and editor of the Lowy Institute’s blog LowyInterpreter.org.
“They still rely very much on foreign technology, and their progress on developing domestic high-performance engines for combat aircraft has been frustrating and slow,” he said.
While the J-31 and J-20 will add to China’s offensive as well as defensive capability, “it will take many, many years” for them to enter service with the air force, Roggeveen said.
 

Tungsten Military -China J-31 Stealth Fighter Plane Prototype Tested Near Shenyang

BEIJING -- China has test flown a second model of a prototype stealth fighter, aviation experts said Thursday, in a sign of its aircraft industry's growing sophistication.
Photos posted to the Internet Thursday showed the radar-avoiding aircraft airborne near the northeastern city of Shenyang with its landing gear still down. Two Chinese-made J-11 fighters accompanied it on the flight, which Chinese military enthusiast websites said took place Wednesday and lasted about 10 minutes.
Ross Babbage of Australia's Kokoda Foundation and Greg Waldron of Fliightglobal magazine in Singapore said the plane known as the J-31 appeared to be a smaller version of the J-20 prototype that was tested last year in the southwestern city of Chengdu.
While both planes feature stealth design features, their true capabilities in terms of sensors, radar-absorbing coatings, and other key factors remain unknown. It isn't known when, or if, either plane will go into production.
"I think it's a fairly straight forward evolution to develop advanced fighters at this time, but you can't read too much into it in terms of capabilities," Waldron told The Associated Press.
The smaller and nimbler J-31 appeared intended for a fighter-interceptor role similar to the U.S. Joint Strike Fighter, while the heavier J-20 would target airfields, warships and other ground targets, he said.
The technical barriers and development costs for such aircraft are enormous and the U.S. has struggled for years to deliver on their potential.
Another major challenge for China is developing engines for its fighters that are reliable and capable enough for such cutting-edge aircraft, Babbage said. China remains overwhelmingly reliant on Russia for engines for its latest J-10, J-11, and J-15 models, the last two of which were developed from Russian Sukhoi fighter-bombers.
"The demands in the engine area are very substantial," Babbage said.China flexes military muscle with J-31 stealth jet

Tungsten Copper Alloy Military Gas Vane



Tungsten copper alloy military gas vane is a device for controlling aircraft; rockets, spacecraft, and the like during those parts of a flight where gas vanes are not effective. Tungsten copper alloy military gas vanes vary in design from plates that change the thrust direction of a gas flow to complicated guide vanes. In aircraft, gas vanes are used during take off and landing conditions .While in rockets and spacecraft they are used during the initial portions of a flight and for control in non atmospheric conditions.
The theory is that when the solid rocket motor outbursts the high temperature, high speed gas flow, tungsten copper military gas vane can make the copper molten in the structure of tungsten skeleton infiltrate, evaporate, then effusion.
When the tungsten copper alloy changing in the phase state, tungsten copper need to intake large mount of heat for the sake of cooling, and the good thermal conductivity of cooper makes the tungsten copper alloy military gas vane with the function of cooling and keep the ablativity at low extent to satisfy the requirements of controlling system.
