J20同其它战机一道完成实战演练 [美国媒体]

The People’s Liberation Army Air Force (PLAAF) announced that its fifth-generation fighter, the Chengdu Aircraft Industry Group (CAIG) J-20, participated in combat exercises along with other PLAAF fighters.

PLA宣布其第五代战机，成飞J20参加了与其它空军战机一同的军事演习。

Reported by the state-owned China Daily, the J-20 undertook a series of tasks, including beyond-visual-range (BVR) air-to-air engagement with the PLAAF’s J-16 and J-10C, which are produced by the Shenyang Aircraft Corporation (SAC) and CAIG, respectively.

由官媒中国日报报道，J20执行了一系列的任务，包括与沈飞和成飞制造的J16和J10C进行的超视距空对空演练。

This marks the first official announcement of the J-20 being fielded following the fighter’s commissioning announcement in October 2017. China Central TV (CCTV) Channel 4 had also stated that the J-20 entered serial production, in which the PLAAF could procure at least 100 fighters (IHS Jane’s Defence Weekly).

这标志着在2017年十月之后，J20首次官宣实场执行军事行动。中央四套电视台也报道了J20开始了连续生产，由此中国空军将能获得超过100架该型战机（简式防务周刊）

Official specifications of the J-20 are not available, but it is a twin engine heavyweight aircraft designed to undertake long-range air-to-air and potentially air-to-surface operations. Powered by two 13+ ton-class turbofan engines, it could have a sizable payload capacity with long-range and long-endurance flight.

对于J20的规格目前还没有官方说明，但它是一款双发重型战机，用于执行长距离空对空和潜在的空对地作战任务。由两台13+吨级的涡扇发动机提供动力，使得J20能够在长距离高强度的飞行中保证有效载荷。

In parallel to the J-20, the Aviation Industry Corporation of China’s (AVIC) other leading fighter producer, SAC, is developing the FC-31 Gyrfalcon for the export market. This is a smaller and lighter-weight design than the J-20, optimized to be a multi-role platform built on two 9-10+ ton turbofan engines.

与J20同步，中航工业另一家先进的战机制造商，沈飞也在为出口市场研发FC-31鹘鹰战机。与J20相比更小更轻，装载两台9-10吨级的涡扇发动机，可以做为高效的多功能平台。

While meant for foreign users, AVIC had expressed interest in 2015 to expressed domestic customers for the FC-31 – i.e. from the PLAAF and/or the People’s Liberation Army Navy (PLAN).

除了面向国外用户，中航工业2015年也表示国内用户也对J31有兴趣——即，中国空军和中国海军。

However, while beginning to induct the J-20, the mainstay of the PLAAF and PLAN’s procurements are tied to the J-10C and the J-11BS/J-15/J-16-series of localized Sukhoi Flankers.

然而，在J20服役的同时，空军和海军采购的主要都是J10C和苏霍伊战机的本土版本J11BS/J15/J16系列。

The latter are benefitting from China’s research and development (R&D) work for the J-20 and FC-31, specifically in terms of radars, electronic warfare and electronic countermeasures, avionics and air-to-air as well as air-to-surface munitions. The serial production of the J-10C and J-15 et. al will remain in place for the foreseeable future, reinforcing their presence as the workhorses of the PLAAF and PLAN.

后者们全都从中国对于J20和J31的研发中获益，特别是在雷达、电子战和电子对抗、航空电子设备还有空对空以及空对地弹药方面。在可预见的未来，J-10C和J15等系列的仍将保持生产，作为干粗活的角色在中国空军和海军中服役。

However, with China’s surrounding region now actively phasing into fifth-generation fighters – most notably the F-35 Lightning II – the J-20 and FC-31 will gradually gain prominence in line with those trends.

然而，随着中国周边相继积极部署五代机——特别是F35——J20和J31的作用将随着这些趋势线逐渐突出。

How is this in thrust vectoring and supercruise?

它在矢量推进和超音速巡航方面怎么样？

    I think J-20 can do both somewhat but not exceptional.
    There are rumors that China is testing thrust vectoring on J-10 and J-20 using WS-10 recently, but very little is known. I think after flying Su-35, China gained some experience on flight control of thrust vectoring and starting to put their own vectoring technology into practice. Turning the nozzles of engines is easy but how that affects the aircraft is something requires experience.
    There are rumors that J-20 can do low supersonic cruise at around mach 1.2 using the latest WS-10, but no official information of course. It is expected to cruise at mach 1.8 when WS-15 is ready, but that could still be few years at least (current estimate is around 2020, but we will see).
    The most notable weakness of J-20 is it’s engines, that is why it’s super cruise ability is nowhere near F-22 and Su-57 (with the new engines), but F-35 can’t super cruise, does not have thrust vectoring other than for take off and landing, still undoubtedly a 5th generation aircraft. Stealth is what counts for 5th generation aircraft and the front stealth of J-20 is considered excellent, on par with F-22 and superior than F-35.
    The most notable strength of J-20 I think is it’s range. Of course no official information is given but aviation exports estimated, based on it’s size and shape, it has a combat radius of 2000+ km on internal fuel, which I think is enough to cover south China sea without air fueling.
    A stealth aircraft of such range is kind of terrifying and I think that is why China is not exporting it.

我认为J20能部分做到，但不会做得很好。
有传言称近期中国正在J10和J20上用w10测试矢量推进，但所能知道的相关信息很少。我认为在飞过了苏35之后，中国获得了矢量推进的一些飞控经验，并开始实际测试他们自己的矢量技术。让发动机的喷管转动是很容易的，但是如何实际用于飞机则需要经验。

有传言称J20可以使用最新版的WS10进行1.2马赫的低超音速巡航，但没有官方消息。预计装配ws15后，它将可以以1.8马赫进行超巡，不过至少还要等上小几年（最新的估计是大约2020年，我们会看到的）。
J20最显着的缺点就在发动机上，这就是为什么它的超巡能力比不上F22和（装备了新发动机的）苏57，不过F35也没有超巡能力，除了起飞和降落时也没有矢量推力，这不妨碍它成为一款五代机。隐形能力对于五代机是一项重要的指标，J20的前隐身非常出色，可以匹敌F22，超越F35。

我认为J20最杰出的优点是它的作战半径，虽然没有官方披露，但是航空专家们根据它的尺寸和外形估计它的内油作战半径超过2000公里，这个距离我认为在没有空中加油支持的情况下足以覆盖南中国海。
如此大作战半径的隐形战机有点太可怕，我觉得这就是中国为什么不将其出口的原因。

    Don’t think it can do either. Primarily a radar evading stealth design with potent EW capability and a poor engine. Intended mission seems to be deep penetration and long range engagements.

不认为它能做到。主要是因为其具有强大电子战能力和虚弱发动机的躲避雷达的隐形设计。它的预期任务看起来是纵深突袭和远距离作战。

    Good question… Plus what are prospects for Pakistan in this news. Only heard about their interest in FC-31. Hope @bilal answers to concerns

好问题，不过这个新闻对巴基斯坦来说意味着什么呢？只听说他们对于FC31感兴趣，希望@bilal能进行回答回复。

Aizad Sayid
Pakistan is not in line to receive these aircraft from China. However, if this fighter aircraft is fully able to realize it’s potential, even 3 squadrons would be enough to neutralize IAF!

巴基斯坦并不能从中国得到这种战机。
如果这种战机能实现它的各项指标的话，只要三个中队就能抵消整个印度空军。

    Muhammad Abdul Rehman Jajja
    They are developing their own version of PakFA 50. Worrying situation is for Pakistan as no one is willing to give us even 4+ gen fighters

他们正在发展他们自己的PakFA50战机。令人担忧的形势是甚至没有人愿意给巴基斯坦四代+的战机。

Khan Majeed
There is no thrust vectoring because it is not a close up dog fighter

没有矢量推进，因为它不是一款狗斗战机。

Shafiq Ahmed
what are the prospects of Pakistan getting these air crafts in future Mr Bilal??

Bilal先生，巴基斯坦得到这些战机的前景如何？

    John Nobody
    In my opinion Pakistan will be more interested in J-31. PAF will probably let China learn from J-20 experience and develop a better product before they consider placing order which means we are about 8-10 years out.

我的观点是巴基斯坦对J31更感兴趣。巴空军大概是等着中国在J20身上摸索出了足够的经验来开发出更好的产品才会下订单，预计将要等上8-10年的时间。
