Serious Xijinping's J-20 5G fighter now use latest 3D vectro Chinese Engine WS15 breakthrough

This is yet another expected results from the pipeline which began years ago, when PRC govt allocated resources to develop such jet engines.

The target max trust 19.7ton and trust/weight ratio 10.5 must have been reached now, so that they put on their new 5G fighter jet J-20, previous last disclosed development prototype reached 16.5 tons 9.5 ratio, was from prototype. Now, it is finally completed. 3D vector exhaust nozzle is in this WS-15 (涡扇-15) engine, meaning their new J-20 will be capable to perform extreme agility maneuvers like the amazing SU-35.

　　5月25日晚10点，央视4播出纪录片“走进中国”-“匠心第四集-工匠之家”中，介绍沈阳黎明发动机公司首席大师，片中直言：歼20发动机为中国第五代“峨眉”（涡扇-15/FWS-15）涡扇发动机。

　　这次公开的信息，直接回击了对中国航空发动机制造水平、能力的质疑和贬低，直接打了迄今一直鼓噪歼-20用俄制的人们一记响亮的耳光！


　　今晚的《走进中国》终于官泄了歼20使用国产发动机，节目中的第5代发动机应该指的就是FWS15。毛发党可以闭嘴了！

　　在沈阳黎明航空发动机集团，人们都在颂扬着一个工匠之家的故事，父亲当年就是企业的一个劳模，儿子孙家宇是个钳工，孙家沧是个电工，但是哥俩在父亲的影响和嘱托下，双双比拼，成长为企业的工人典范，成为企业的技术能手，分别在沈阳“振兴杯”中获得前三名的好成绩。（作者署名：青峰）

Is can be expected that J-20 with a stronger canard (front wing) should be able to perform high agility maneuvers more than the SU-35/37 which canard is tiny. Plus, J-20 is 1.5 tons lighter than SU-35.

older video last year:

Confirmed WS-15 in mass production! Likely higher performance than the imported Russian engines.

And Chinese are already in the design stages of NEXT engine post WS-15! They are fastest and will never stop!

I suspect Hongkie made this video because of ???

So called 3D Trust Vector Control is nozzle's X-Y 2D directions plus Diameter control, so 3D is not XYZ but XYD, D=diameter.

F-22 is very poor only 1D = Y Direction only, no X direction & no Diameter controls!

By far the most impressive Chinese arms development is their anti-missile defense. Almost like having bullets that can shoot down other bullets in mid-flight. In this case, their anti-missile missile is superb. Impossibly accurate at over 20 Mac.

The next and final watch area is nuclear sub, since in every other arenas Chinese had exceeded USA. There at least one known super huge factory/shipyard that can simultaneously construct 6 type 094/095 new nuke subs. The Chinese wants in their navy dozens of these. They are huge twin hull composite material subs, super silent unlike steel hull, stealth to sonars, use water jets instead of propellers.

涡扇15仍需等待 歼20配该航发量产可1.5倍音速巡航
涡扇15仍需等待 歼20配该航发量产可1.5倍音速巡航

680

　　日前，歼-20专属发动机涡扇-15传来好消息，最后大关取得突破全民为之振奋。可是，中国涡扇-15三维矢量喷口发动机需要反复试验，至少需要3到4年才能装配部队。

　　然而，歼-20批量生产迫不及待，涡扇-15远水解不了近渴，面对中国空军急需情形，难道就只能干等着吗？

　　答案当然是否定的，毕竟这么多年中国速度并非浪得虚名。

　　近日，据媒体报道，中国歼-20新一代批量生产型已经开始装配涡扇10-IPE型增推发动机，加力推力高达14吨左右。以歼-20尾翼双发结构来看，歼-20双喷至少拥有1.5倍音速巡航能力。就如歼-20飞行员所说，只要已进入超音速，歼-20就是所向无敌的。

歼-20换上国产发动机试飞
　　相比美国F-22和俄罗斯苏-57，歼-20还是有略微差距在哪。曾经令全球竖起大拇指的F-22能以1.6倍音速实现超音速巡航，其F-119发动机推力可达12吨，加力推力情况下能实现1.7倍音速巡航。

　　而俄罗斯最新换装的30系列发动机和F-22的F-119发动机性能相近，差距不大，结合机身重量，在正常情况下两者都能达到1.6倍音速左右。

　　歼-20的机身重量仅有15吨，比美国F-22和俄罗斯苏-57足足少了5吨，所以即使是军用推力只有10吨的发动机，也能让歼-20以1.5倍音速超音速巡航。

　　然而新一代先进战机间早就不是原来所追求的超机动性能，而更侧重于超视距打击和隐身能力。这恰巧是苏-57的致命弱点，所以歼-20领先苏-57还是绰绰有余的。

F-22战机
　　对于F-22，航电系统相对老旧，还有它本身的机体结构在众多五代机中就不占优势，当初过于倚重隐身能力导致现在的作战能力无法突破原有的高度。

　　而歼-20在设计时兼顾了气动布局和隐身能力，此外，还应用了智能蒙皮技术、飞火推一体化控制系统、有源相控阵雷达装置，无论是机动性还是隐身性能，综合起来都超过美俄五代战机，就连俄罗斯专家都对歼-20赞许不已。

　　此前，美国专家预计中国歼-20要到2018年才可以进行量产工作，出乎意料的是，歼-20在2017年就实现了批量生产，并列装部队，毕竟“脉动生产线”的效率是另全世界跪服的。

　　美中不足的是歼-20的超音速巡航时间有限，与同代机型对抗基本不占太大优势。但是随着涡扇-15的列装，歼-20就会成为真正的强者。（作者署名：前沿哨所）
