First, WS-10G produce 155KN of thrust which is more than your 117S (147KN). This means it will also be able to produce more power to power J-20's AESA. China does NOT need Russia any more on this one.

Second, Irbis-E is NO MATCH for APG-77. Irbis-E is PESA it does not have low probability of interception which means it is not stealth at all. Irbis-E also not as good in terms of high jamming resistance. It has longer range? True, but only by a little.

Last, Wiki is not good, ONLY for political informations. As for technical stuff, it is ok.

The 117S has nothing to do with the pak-fa, get your facts strait.

And guess what the 117S is a production engine, the WS-10G is not and it is not clear when it will be. Moreover, the AL-41 produced 40,000 lbs thrust 21 years ago so ah...what is your point? There is also a 117 engine not to be confused with the 117S, its T/W ratio is 10.5:1. T/W is what is important not totall thrust, understand? And the production pak-fa will use neither the 117 nor the 117S.

Faster than i expected.

 

[Project 627]

lol, so much credibility here.

Far more credible then claiming you buy their engines so you can address the trade deficit issue with Russia

The smoke funnel of the 3rd 052C is white color, it may indicate different power plant compare with first 2 ships of the class. Everything else looked identical.

 

[Chinese Century]

time for the greatest naval build up in human history and deploy every destroyer, frigate, submarine to protect chinese territory in the south china sea from barbaric war mongering enemies such as the brutal dictatorships of india, vietnam and philippines.

its time to play hard ball.

china needs hawks in power in 2012.

and its about time china repealed the no-first-use policy on nukes.
i say china needs to keep all options on the table to deal with aggressors like india, vietnam and phillippines.

are you HongWu??

Seems to be him

China is the decisive stabilizing factor in Asia as because if her might, many mischievous, self proclaimed regional powers have to think many a times before conducting a mischief.

Ok, but you do have to addmit that the current PAK-FA uses S-117 engine right??

I think the new ones lunched are actually 052+ with matured system and upgraded capabilities.


4 052C+ and 2 052C are going to be the backbone of China's carrier fleet defence.

Sorry to go off topic but i'll answer the man's question.


The second prototype uses the 117 engine, it is not the same engine as the 117S. The production engine is still under development.

Ok, good. So you must addmit that PAK-FA has no engine edge over J-20 right?

Because now, J-20 uses WS-10G which is very much alike the S-117 engine. Also, the main engine for J-20, WS-15 is under development!


Sorry for going off topic!

Sure you are.
so your telling me you buy one of the most important military hardware on earth so you could just solve the trade inbalance issue with Russia, what a load of B.S.
NO you buy their engines because of the reasons below me.

Chinese Engines Miss The Finish Line

PLEASE NOTE: the total life of basic version of AL-31F/FN is only 1500 h, time between overhauls(TBO)-500h,far short than the airframe life.

...По сравнению с двигателями АЛ-31Ф в 2-2,6 раза возросли ресурсные показатели. Межремонтный ресурс увеличился с 500 до 1000 часов. Ресурс до первого капитального ремонта - 1500 часов. Назначенный ресурс увеличился с 1500 до 4000 часов.

Big New Chinese Order for Russian Fighter Engines

China has placed additional orders for Russian AL-31-series fighter engines. State arms trade agency Rosoboronexport clinched two big contracts earlier this year. One is for more than 150 AL-31Fs as replacements for earlier engines of same type that power the Su-27/Su-30MKK/MK2 fighters, that are designated J-11 in China. Engines under this contract will be assembled by the Ufa-based UMPO factory.

The second contract is for more than 120 AL-31FN engines to power newly built Chengdu J-10 fighters. Engines under this contract are already being delivered, from the Moscow-based Salut plant.

Speaking to AIN at the Aviation Expo 2011 in Beijing, Salut general director Vladislav Masalov said that negotiations continue on a second batch of nearly 140 AL-31FNs and that a follow-on contract is expected to be signed in October.

Masalov further said that the grand total of Salut-made AL-31 series engines in China “is nearing one thousand units.” To serve them, Salut has established partnerships with Limin Corp. and Tyan Li company in Chengdu on deliveries and manufacturing of spare parts for both the AL-31F and the AL-31FN. Russia has also agreed to provide all necessary maintenance and repair documentation to the Chinese partners. Salut faces many issues pertaining to ramping up production to fill these big Chinese orders, Masalov said. This year the company must increase its production output by 30 to 40 percent to fulfill the Chinese contracts. “Certainly there is some pressure on us, with bottlenecks being metal and vendor items,” Masalov said.

Meanwhile, Salut is negotiating the sale of another 40 AL-31FM1 engines to the Russian Air Force for the Su-27SM upgrade. Twelve have already been ordered. Talks to supply AL-31FM2 versions for the Su-34 continue, Masalov said.

TWR>10 ,source?highly doubtful. maybe based on the russian standard?

The Russian standard is different from the US standard.

According to the US standard, the 117 engine should be around 8.5 in its T/W.

The F119 engine is around 10 in its T/W, but it was only 9 in its early days of service.
