All the Technology contents lie in the parts for assembling the Engine, Design work is carried out by the licencer.

Even aproduct as low technology content as shoes can say thing: China manufactures 90% of Nike shoes, however, the bulk of money is only earned by the US HQ company while China is still risk of trade saction by those western countries because of exporting all those shoes.

So no need mention high-tech products like Turbofan engines

i want to know more about this. Could you(or anyone) give me a list of major tecnologies/designs that china obtained/stole from the West in the 80’s ?

Got this extracted from the long article as shown below

US National security And P.R.China

In 1983, the PRC legally acquired two General Electric CFM-56 jet engines, ostensibly to analyze the engines for a potential civil aircraft upgrade program. In the course of the export licensing process, the Defense Department insisted on restricting the PRC’s use of the engines. Under the terms of the licensing agreement:

No technical data was to be transferred with the engines; the Chinese were not to disassemble the engines; and finally, if the Trident [civil aircraft] retrofit program had not begun within 1 year of the engines’ arrival, the engines were to be repurchased by the manufacturer. In addition, the Chinese offered to retrofit engines at a Shanghai commercial aircraft facility where GE personnel would be able to monitor Chinese progress.87

Defense Department officials were concerned because the CFM-56 hot sections are identical to those used in the engines that power the U.S. F-16 and B-1B military aircraft.88

The PRC later claimed that the CFM-56 engines were destroyed in a fire.89 More likely, however, is that the PRC violated the U.S. end-use conditions by reverse engineering part of the CFM-56 to develop a variant for use in combat aircraft.90

Despite the suspected reverse engineering of the two General Electric jet engines that were exported in 1983, G.E. reportedly signed a contract in March 1991 with the Shenyang Aero-Engine Corporation for the manufacture of parts for CFM-56 engines.91 According to one source, Shenyang “put in place quality and advanced manufacturing systems to meet US airworthiness standards.” 92

The PRC aggressively attempted to illegally acquire General Electric’s F404 engine, which powers the U.S. F-18 fighter.93 The PRC likely intended to use the F404 jet engine in its F-8 fighter.94 The PRC succeeded in acquiring some F404 technology through an indirect route by purchasing the LM-2500, a commercial General Electric gas turbine containing the F404 hot section.95

In addition, G.E. has reportedly proposed a joint venture with the PRC to manufacture the so-called CFM-56-Lite. The engine could power the PRC’s planned AE-100 transport.96

The PRC also has targeted large engines for aerospace and non-aerospace applications. The PRC’s acquisition plans reportedly include Pratt & Whitney JT-8 series engines and technology to support its large aircraft projects, as well as marine derivatives of the G.E. LM-2500 for naval turbine propulsion projects.97 Regarding the JT-8 series:

In August 1986, CATIC licensed the technology for the U.S. Pratt and Whitney FT8 gas turbine engine, including joint development, production and international marketing rights. The FT8 is a development of the JT8D-219 aero-engine (used to power Boeing 727, Boeing 737, and MD-82 aircraft), and can produce 24,000 kW (33,000 hp). [It] represented another significant technical leap for China’s gas turbine capability . . . Chinese students were also sponsored by Pratt and Whitney for graduate level aerospace training in the United States.98

and every now and then i hear about some thrust vectoring for the WS-10 …how true is this ??

There’s only a photo of Former President JZM inspecting the nozzle, no further info

Will there be an engine order for the J-11? That’s the next important question since it has many implications. But currently it seems China has chosen to build more J-10s over J-11s, but we have to wait and see if the new support agreement would also lead the way to China ordering a new batch of engines for the J-11 or a new batch of fully built Sukhoi fighters like Su-30s.

I won’t agree too much on more J10 will be built over J11.

China chooses the imported Engine for J10 over home made FWS10A for J11 indicates PLA makes the finally decision sidelining J10, this may echo Rick’s point, however, I won’t say the J10 is dying, it’s only will be sidelined.

If we take into account 3 news appeared at almost same time, then we may balance out my view.

1st , China imports 100 Al31FN or so for J10,

2nd, China finally moves on to produce FWS10A

3rd, Shenyan SAC reveals a new model of Fighter jet, widely believed to be J11B

The FWS10a was tested on a J11 twin engine testbed, the PLA is cautious for just moving the new engine to a single engine powered J10A

The plant manufacturing FWS10A is linked to SAC, and its limited initial production is not satisfied to supply both SAC twin engine powerd J11B and CAC’s J10. After much frustrated debate, the Chengdu CAC apparently stuck to mature AL31FN supply. There are still competitive relation between CAC and SAC.

Just as a hedge step, PLAAF is still suspicious about the new engine of FWS10a, scare of what happened to the American F100 engine at initial stage. So, import a proven engine like AL31 is a double insurance. This arrangement just like PLAN building 052C while still imports Rif-M system.

Based on above judgement, so, I won’t see any future massive import of AL31 for the J11B, If such does happened, then it’s really a big blow to the China’s aviation industrial.

Is this reported BVR AAM PL-12?

Missile advance

http://www.washingtontimes.com/national/inring.htm

Pentagon officials tell us China’s recent flight test of a new 6,000-mile-range JL-2 submarine-launched ballistic missile earlier this month was not the only recent troubling development in Beijing’s military buildup.
About the same time as the JL-2 test, China also test-fired a new long-range air-to-air missile.
“The missile has over-the-horizon capability, something they have not had before,” said one official familiar with the test.
Defense analysts believe the missile, which was not identified by type, could be one of China’s new PL-12 air-to-air missiles, an indigenous missile that has beyond-visual-range radar guidance and targeting.
Air Force Gen. Paul V. Hester, commander of Pacific Air Forces, said in a recent meeting with reporters that China’s fighter modernization is being watched closely and warned against underestimating Chinese military air power, as occurred with Soviet warplanes during the Cold War.
“They have great equipment. The fighters are very technologically advanced, and what we know about them gives us pause or concern against ours,” he said.

Wow, While the IAF may be spoilt by choices, the local arm industry would suffer another headache.

I think there r a number of mistakes in the Taipei Times report, for example: “Weng said China probably would deploy the Ju Lang-2, which carries nuclear warheads, on its Han-class nuclear submarines”, Han Class is Type 091 an aged SSN.

Here’s another more moderate report from Japan source:

China test-fires new submarine-launched missile

http://www.timesleader.com/mld/timesleader/news/world/11923372.htm

The Yomiuri Shimbun

TOKYO – (KRT) – China test-fired a new long-range, submarine-launched ballistic missile Thursday, Japanese government sources said Friday.

The new missile is believed to be the Ju Lang-2, a modified version of the intercontinental ballistic missile Dong Feng-31 that has a range of about 8,000 kilometers.

The new SLBM was believed to be fired from a nuclear submarine in waters off Qingdao and touched down in a desert in China several thousand kilometers away.

It has been confirmed that China test-fired an SLBM in 2001.

China is believed to possess about 30 ICBMs and has been conducting research on multiple-warhead missiles to counter the U.S. missile defense system.

China also has been more active recently in its naval operations. In November, a Han-class nuclear submarine cruised around Guam and entered Japan’s territorial waters. If China develops SLBMs further, the entire mainland of the United States would come within range of the missiles.

Observers said the latest test-firing apparently was aimed at warning Washington not to interfere in the event of military conflict between China and Taiwan in the Taiwan Strait.

The United States believes China is ready to deploy the Dong Feng-31 and has estimated that Beijing will have 100 warheads targeting the United States by 2015.

U.S. Defense Secretary Donald Rumsfeld expressed strong concern over China’s development of ICBMs in a speech in Singapore on June 4, saying China appeared to be improving its missiles targeting the Asia-Pacific region and also was expanding its missile capability to reach any target in the world.

Wow, bigger and clearer picture, Is this J10 really as the caption suggested, belongs to PLAAF 7th Div stationed in Northwest Shanxi Province? See, what missile under its left wing.
