KJ-500 and other specialty aircraft

Thanks a lot for posting. I just read yesterday that at the tarmac 4 more KJ-500, at least 2-3 Y-8GX-6 (KQ-200 ASW) and several more special mission birds were spotted.

@Beast @wanglaokan
what is the number of J10s and flanker variants PLAAF have?
do we have a guesstimate?

Updated in November 2015 :

A rough estimate of the number of modern PLA(N)AF fighter aircraft:

A typical PLAAF regiment consists of 28 aircraft.
A typical PLANAF regiment consists of 24 aircraft.

J-16:
- 28 aircraft per regiment X 1 regiment = 28 J-16

J-10:
- J-10A: 10 PLAAF regiments X 28 aircraft + 1 PLANAF regiments X 24 aircraft = 304 J-10A/S
- J-10B/C: 53 J-10B + 12 J-10C = 65 J-10B/C
Total: 304 + 65 = 369 J-10

J-15:
10 + 5 = 15 J-15

J-11B:
9 PLAAF regiments X 28 aircraft + 3 PLANAF regiments X 24 aircraft = 324 J-11B of all variants

J-11A:
- Su-27UBK/SK (imported): 24 + 26 + 28 = 78 Su-27UBK/SK
- J-11/A: 104
Total: 78 + 105 = 182 J-11/A and Su-27

Su-30:
- Su-30MKK: 38 per batch X 2 batches = 76 Su-30MKK
- Su-30MK2: 24
Total: 76 + 24 = 90 Su-30

JH-7:
- PLAAF: 120
- PLANAF: 120
Total: 240 JH-7

GRAND TOTAL:
324 + 182 + 369 + 15 + 90 + 240 + 28
= 1248 4/4.5th generation combat aircraft

Note:
- Older generation aircraft were not included
- Force multipliers (i.e. AEW/EW aircraft) were not included
- Numbers are likely to be even higher due to production

Aircraft currently in production:
- J-10C
- J-16
- J-15
- J-20

The numbers of AL-31s bought does not tally with this number...You need to remember at least some spare engines per aircraft, other than using domestic WS-10A, there is no logical explanation.

It's True.
That All Shenyang J-11B/BH dan J-16 using WS-10A Taihang Engine.

Total using that 2015 Data :
326 J-11B/BH + 28 J-16 (x 2 WS-10A Taihang Engine per Unit) = 804 Unit WS-10A Taihang Engine on Use
not including for Spares.

how many Al 31 were brought orginally

 

[cirr]

SAC

 

[lcloo]

PLAAF IL-76 and Y8 air drops IFV with heavy duty parachutes.

 

[rcrmj]

how many Al 31 were brought orginally

over a thousand`````

 

[帅的一匹]

over a thousand`````

J10c is using WS10 with Al31 like petals?

 

[grey boy 2]

Jacksonbobo pictures taken for the country 我为共和国拍照

 

[rcrmj]

J10c is using WS10 with Al31 like petals?

as far as I know the J-10B/Cs are using al31

 

[帅的一匹]

Which means WS10 will never fit on J10 in volume right?

 

[Beast]

as far as I know the J-10B/Cs are using al31

J-10B/C do not used AL-31FN engine. There are domestic made uprated hybrid engine that only external looks like AL-31FN.

AL-31FN engine cannot give the kind of 145kN > thrust required by PLAAF. Russian has no means to uprate the engine to help China project. There are basically the same engine used on J-20.

 

[Beast]

Turbofan and fighter jet is not LEGO toys that you can add bits and bots as you wish! changing the core is pretty much redesigning the whole```

Let me ask you one thing, can you easily differential WP-13F(based on Russian R-11) and WP-14 kunlun engine?

WP-14 kunlun engine is claimed to be first independently develop Chinese engine with IP right. It has 50% more thrust than WP-13F. It do not share any core from R-11 engine and yet it does not look much different from it except the shiny engine petal.

Now is not a matter of what u claim. Fact is J-20 engine is domestic made and assemble at shenyang liming. Are u going to deny it?

【成果简介】
1.任务来源 轴型叶片的检测主要包括叶片型面、安装角度、叶尖圆锥面的检测,要完成上述检测,使用现有测具,每1种轴型叶片需要4套测具,其中,1套用于检测安装角度,1套用于检测叶尖圆锥面,两套用于检测叶片型面(叶片型面需粗、精各1套测具)。由于轴型叶片的种类繁多,因而需要非常多的测具,这不仅难于保证叶片加工的工期,而且极大增加叶片的加工成本(每套测具的制造周期需要几十天,制造成本需几千至一万多元人民币)和保管成本。 基于轴型叶片加工中行业中普遍存在的生产成本高,制造周期长,客户评价差,制造技术停滞不前的现状,根据当前成都发动机(集团)有限公司轴型叶片的当前订单情况和立足发展国内外轴型叶片加工技术的目的,公司自立本课题。

2.项目所属科学技术领域 本项目属航空技术领域,涵盖所有军民用航空发动机和燃、汽轮机不同型号的轴型叶片检测,已应用到国内606所,624所,商发,美国GE公司,日本三菱,欧洲、加拿大等几家航空公司占全球15%比例以上超过60万件轴型叶片的检测领域,并在进一步扩大应用范围。

3.主要内容 为克服现有技术的不足,成都发动机(集团)有限公司研制了一种轴型叶片通用组合测具,这种测具通过设计的通用定位块、压紧块、工艺角度定位块、型线样板、活动截面定位块组合可以实现不同型号叶片的轴向定位和角度定位;通过安装角度测量装置、底座、通用定位块、安装角度辅助定位块可以实现被测轴型叶片的安装角度测量;通过活动截面定位块、标尺、底座、样板可实现被测轴型叶片的叶型测量;通过标尺、活动截面定位块、叶尖圆锥面测量块、叶尖辅助定位块等可实现被测轴型叶片的叶尖圆锥面测量。这样,一套测具就可完成多种型号轴型叶片的型面、安装角度、叶尖高度检测,因而大大减少了测具的数量。同时,由于测具的通用性强,因而新型号的轴型叶片不需要再制造新的工装,整个叶片的生产周期大幅度缩短,生产成本、维修成本和保管成本明显降低。

4.特点 本项目相对于现有技术采用的测具,结构简单精巧,测量精准可靠,能够很大地降低生产周期和制造成本。国内外行业内厂家尚无与类似产品,本项目在国际上居于领先水平。其特点体现在：
(1)采用带蝶形压紧螺母的V型定位块,对不同轴径的叶片进行定位;采用角度样板,对带安装扁的叶片进行定位;采用角尺,对叶型上有工艺扁的叶片进行定位;采用截面样板,对无安装扁和工艺扁的叶片进行定位,由此解决了所有轴型叶片的定位问题。 (2)采用活动叶型截面定位装置,通过内凹的锁定结构和与疏板配套的T型滑动通槽,实现了不同截面叶片型面的测量。
(3)通过加长疏板整体基准面,设置安装角度配套样板和叶尖圆锥面测量块,实现了安装角度、叶尖圆锥面与叶型截面的组合测量。

5.应用推广情况 本项目产生的直接经济效益2162.7万元,新增叶片订单14万余件,新增产值7209万元,增加了10余台大型轴流风机和7台GT200高炉煤气余温余热透平发电装置的订单,并顺利完成QC185、QC400、GT25000G军用舰载燃机轴型叶片研制,WS18,WS19涡扇发动机轴型叶片研制,624所AT项目无人机等型号攻坚任务等。 本项目极大缩减了军、民用轴型叶片的研制周期和制造成本,提高了国内外轴型叶片的测量技术水平和生产制造能力,对全球航空事业、电力事业和其他动力事业的发展起到了的推进作用。
