China Flanker Thread II

[Air Force Brat]

It's always possible to design the 2 aircraft's aft fuselage structure to accomodate both engines. The holding brackets for the 2 type of engines will necessary be different but they should have no problem fitting into the aft fuselage if they are designed to do just that to begin with.

But the same cannot be said for the older aircraft and, even production aircraft, since doing so may impose a penalty on the aircraft, for example an increase in the weight of the structure.

Come to think of it, in the case of the production, or even the prototypes, J-15, it's quite likely the the aft structure is already optimised for the WS-10H engine without necessating the use of a holding bracket.

I would say that the prototype is specially modified to house both engines and it is honestly fairly typical to fly a developemental engine alongside the current production model for the purpose of retaining the reliability of the production engine. It is not uncommon to shut down an engine that exceeds the design limits in some ways and many turbines are shut down on initial start-up if the temps exceed a certain limit, however once running and up to temp, turbines are overall very reliable. It wouldn't require a great deal of engineering to adapt an airframe to run a choice of engines, and one of the F-35 issues was the development of an alternative engine which has been since been D/Ced due to cost.

the translation indicated the hardware or a prototype model already exist,the problem may be solfware.
problem mirror image that of US and european AESa program.developing a solfware are far more complicate and expensive than hardware.
transaltion claim that PESA for J-10B is base on russian design,likely is mosquit or Mosquito PESA radar, 2 radar set were sold to china in 2004.and may have use a base for J-10B PESA program.

Keep in mind that this is a russian news source. But the fact that chinese quote them only shows how desperate some are for information.

Very much true. In fact, there are many and regular Chinese translations of various Russian news/commentaries on Chinese defense matters. The funny thing is many of the news are actually originated in China, reported on Russia or English media, and then translated back to Chinese again under slightly different format.

There are just so much demand for information, any information related to Chinese defense matters.

PHAZOTRON’S RADARS
for fighter jets and helicopters
Interview of Phazotron-NIIR Corporation Designer General Yuri Guskov



I would like to emphasise that China did
not copy the radars we had developed. Radars
are not something that can be copied easily.
We use our own electronic componentry and
the Chinese use theirs, and they are different.
However, our cooperation gave a considerable
impetus to the Chinese radar development, no
doubt, and NRIET has turned into the major
aircraft radar developer in China.
Now, our Chinese partners propose
cooperation in AESA radar development

Prototype 551 with one AL-31F + one WS-10H !!!

... so much for both engines are not interchangeable on the latest Flanker versions .... and as such why not n the latest J-10B too ?

Off topic from the engine discussion, but I could not help but notice the A2A missile test units on the wing tips here. Do not recall seeing that on other prototype J-15s which means they are beginning to qualify weapons, though we do not know when the photo was taken.

A good sign for the J-15 in any case.

I absolutely agree, and one of the many good reasons for the Chinese to expand the Flanker Fleet is that many of these systems are tried and tested, the J-15 is really just another production version as evidenced by the fact that they build "runs" of different versions. The J-15 is reaching rapid maturity due to this pathway to certification, not saying there may not be issues, but those issues won't be game-changers, and this weapon will achieve full capability in a much shorter time frame than say the J-31 for this reason.

Precisely. The J-31 and J-20, for example, are completely new builds and will have to develop these systems anew, specifically for these platforms. But, as you say, the J-15, though a new build and better than the older SU-33, is also building on the PLANs and PLAAFs knowledge of already compatible and tried and true systems which it can integrate into its very similar and compatible platform.

Remember Chinese got tech from MiG-21 and developed it into dozens of variants. Would Flankers repeat the history?

They already have done several...and I believe there will be more to come too...ie EW aircraft, perhaps linked and CE AEW aircraft from the two-seater config, buddy stores for refueling, etc.

看到14所的AESA机载火控雷达天线的结构图了

跟607的很不一样




607的天线方案类似毛子的。14所类似老米







不是20的。应该是16的







could this blogger correct after all.
607 institue AESA radar resemble phozotron,since there is cooperation between China abd russia on AESA development.possibility that 607 (shuzhou) adapt phozotron "stick" solution?
while no. 14 (nanjing) adapt vivaldi slotted array configuration for max. T/R MMIC density.
