F-22和F-35的绞杀机? 中国歼-20隐形战机能否成为顶级空战机

F-22 or F-35 Killer?: Could China’s ‘Heavy’ J-20 Stealth Fighter Become the Ultimate Dogfighter? F-22和F-35的绞杀机?中国现在的“重型”歼-20隐形战机能否成为顶级空战机?   In January 2011, the maiden flight of a large, dagger-like grey jet announced that China had developed its first stealth aircraft—the Chengdu J-20 “Mighty Dragon.” Six years later, after several substantial revisions, J-20s entered operational service with the People’s Liberation Army (PLA) Air Force. As radar-guided missiles from fighters and ground-based launchers threaten aircraft from dozens, or even hundreds of miles away, stealth capabilities are increasingly perceived as necessary for keeping fighter pilots alive on the modern battlefield. 2011年1月,一架形似匕首的大型灰色喷气式飞机的首航宣告了中国已研发成功第一架隐形飞机——成都歼-20“巨龙”。六年后,经过几轮改进,歼-20进入中国人民解放军空军服役。 来自战斗机和地面发射器的雷达制导导弹可以威胁数十英里甚至数百英里以外的飞机,人们越来越坚信,为了让战斗机飞行员能在现代战场上生存下去,战斗机必须拥有隐形能力。 19b9b9782c712a210431f30d42b2c6cd.jpg But just how good is the J-20? And what is its intended role? After all, America’s first stealth fighter, the F-117 Nighthawk, was not even really a fighter and lacked any air-to-air capability whatsoever. The PLA has, true to custom, kept its cards close to the chest, and has not shared performance specifications to the public. Thus, there are broad estimates of the J-20’s top speed (around Mach 2), and considerable-seeming range (1,200 to 2,000 miles), but those remain just that—estimates. For years, analysts even over-estimated the aircraft’s length by two meters. It’s broad but relatively shallow weapons bay can accommodate four to six long-range missiles or bombs, though not munitions with especially heavy warheads. 但是歼-20到底有多出色呢?它在军中能发挥什么作用?毕竟,美国的第一架隐形战机,F-117夜鹰,根本就算不上真正意义上的战斗机,不具备空对空战斗能力。 中国人民解放军一如既往地低调沉默,并未公开战斗机的性能指标。因此,人们对J-20的最高速度(大约2马赫)和射程(1200到2000英里)众说纷纭,但都还只是猜测。多年来,分析人士甚至把飞机的长度估多了两米。它的武器舱很宽,但进深相对较浅,可以携带4-6枚远程导弹或诈弹,无法装载重型弹头等弹药。 International observers generally concluded the large twin-engine jet possessed high speed and long operational range, but that the Mighty Dragon lacked the maneuverability necessary to prevail in close engagements with enemy fighters. Relatively modest aerobatic displays in the Zhuhai 2016 and 2018 airshows (you can see some of the latter here) reinforced the narrative in certain quarters that the J-20 isn’t optimized for gut-wrenching air combat maneuvers. 国际观察人士普遍认为,这架大型双引擎喷气式飞机拥有高速和长距离作战性能,但巨龙缺乏必要的机动性,无法在与敌方战斗机的近距离交战中取胜。在2016年、2018年珠海航展上,中规中矩的特技表演在某些方面也印证了J-20尚无法适应激烈空战演习的说法。 Given the above premises, observers mostly speculate the J-20 would either serve as long-range supersonic strike plane, or a hit-and-run interceptor used to slip past fighter screens and take out vulnerable supporting tanker and AWACS planes. However, Rick Joe of The Diplomat argues these theories of the J-20’s supposedly specialized role might be a case of group-think, ignoring both design features and statements by Chinese sources suggesting the J-20 was intended as a multi-role fighter with “competitive” dogfighting capability. 鉴于此,观察人士大多猜测,歼-20要么作为远程超音速攻击机,要么作为打完就撤、在战斗机旁一闪即过、攻击脆弱的加油机和预警机的拦截机。 然而,《外交官》杂志的里克•乔认为,这些关于歼-20角色的猜测,可能只是一种群体思维,忽略了设计特点和中国消息人士的说法,即歼-20是一种多角色战斗机,具有“优异的”空战能力。 For example, a brochure distributed at Zhuhai 2018 explicitly stated the J-20 was capable of “seizing & maintain air superiority, medium & long range interception, escort and deep strike.” In other words, a multi-role fighter.  “A commonly insinuated premise is that the Chinese aerospace industry was not capable of producing a fifth generation air superiority fighter, and would have to “settle” for a less technically challenging interceptor or striker instead,” Joe argues. 例如,在珠海2018年航展发布的宣传册中明确指出,歼-20具有“抓住和保持空中优势、进行中程和远程拦截、护航及深度打击”的能力。也即多角色战斗机。 “大家普遍有一种偏见,中国航天工业没有能力生产第五代空优战斗机,将不得不“退而求其次地满足”于技术难度较小的拦截器或攻击机,”乔称。 He points out that the lengthy J-20 is still shorter than the Russian Su-35 Flanker-E, one of the most maneuverable jet fighters ever designed. He further cites a 2001 study by Song Wecong, mentor of the J-20 designer Yang Wei, which you can read translated here. Wecong wrote that stealth aircraft “must have the capability to supercruise and perform unconventional maneuvers such as post-stall maneuvers.” Song concluded the ideal stealth fighter would incorporate canards (a second, small set of wings close to the nose of the plane), leading-edge root extensions (or “strakes,” a thin surface extending where the wing emerges from the fuselages), and S-shaped belly intakes, in order to balance stealth, speed and maneuverability. These are all design characteristics evident in the J-20. 他指出,J-20的长度仍比俄罗斯苏-35 Flanker-E短,后者是有史以来最具机动性的喷气式战斗机之一。他还引用了2001年宋伟聪(音译)的一项研究,宋伟聪是歼-20设计师杨威的导师。伟聪称隐形飞机“必须具备超音速巡航能力,能执行失速后等非常规机动”。 宋总结说,理想的隐形战斗机应该拥有鸭翼(靠近飞机机头的第二副小机翼)、前缘根部延伸(或“弦”,机翼从机身伸出的地方延伸出来的薄层)和s型腹部进气道,以平衡隐形、速度和机动性。这些都是J-20设计上的明显特点。 While details on the J-20’s radar remains elusive (presumably a low-probability of intercept AESA radar), it also mounts arrays of electro-optical and infrared sensors with 360-degree coverage, reportedly designed to fuse sensor data to form a common “picture” and even share it with friendly forces via a datalink—technology seemingly modeled on the advanced sensors found on the American F-35. Such sensors could be particularly useful for detecting radar-eluding stealth aircraft. J-20 pilots also are equipped with helmet-mounted sights that allow them to target high-off-boresight PL-10E heat-seeking missiles within a 90-degree angle of the plane’s nose simply by looking at the target. The short-range missiles are stored in small side-bays but can be cunningly rotated outside prior to launch, as depicted here. 尽管歼- 20的雷达能力尚不为人知(应该不太可能拦截AESA雷达),还全身安装了光电和红外传感器阵列,据报道,这是为了将传感器的数据融合成完整的“图片”,甚至还可以与友军通过数据链进行分享,该技术模仿了美国F- 35的先进传感器。这种传感器对于探测能躲避雷达的隐形飞机特别有用。 J-20飞行员的头盔上还配备了瞄准器,使他们能够在观察到目标时,在机头90度角度范围内瞄准大离轴PL-10E热寻导弹。短程导弹存放在小型侧舱中,但可以在发射前巧妙地旋转至外侧,如图所示。 While the J-20 would likely remain outclassed by the F-22, it could potentially prove a dangerous adversary to the F-35, which is not as optimized for within-visual-range engagements. However, both the F-22 and F-35 are believed to have a significantly lower all-around RCS than the J-20, though the Chinese fighter still appears to be significantly stealthier than the Russian Su-57. A 2011 analysis by Australian aviation expert Carlo Kopp concluded that J-20 probably had strong stealth from a frontal aspect, but a larger radar cross section (RCS) when scanned from the side or rear—a limitation also found in the Russian Su-57 stealth fighter. 尽管J-20可能仍远远不及F-22,但它可能会成为F-35的一个强有力的对手,因为F-35在可视范围内的作战能力并不优秀。然而,F-22和F-35的全面雷达横截面都比J-20少,不过中国战斗机看起来仍然比俄罗斯苏-57隐形得多。 2011年,澳大利亚航空专家卡洛·科普在一份分析报告中得出结论,J-20可能从正面具有强大的隐身能力,但机身侧面或后部的雷达截面要大一些——俄罗斯苏-57隐形战斗机也存在这种缺陷。 But as the extent and type of the radar-absorbent materials used affect RCS, visual analysis alone cannot determine how stealthy an aircraft is. This has not dissuaded the U.S. Marine Corps from a building a full-scale mock-up of a J-20 in Georgia for study and training purposes. The Indian Air Force has boasted its Su-30 Flankers have tracked J-20s on radar, but as stealth fighters often employ emitters called “Luneburg Lens” to enlarge their RCS on routine flights, and thus conceal their true capabilities, it’s difficult to infer much from this either. Another issue confusing analysis of the J-20 is that it doesn’t yet have the high-thrust WS-15 turbofans the PLAAF envisioned for them, and are making do with Russian AL-31F engines instead. Even China’s fourth-generation jets have been frustrated by deficient jet engines. The WS-15 generates 23 percent more thrust than the AL-31FN, and would enable the J-20 to super-cruise, or sustain supersonic speeds without resorting to fuel-gulping afterburners. Thus, certain more aggressive projections of J-20 performance, such as a top speed of Mach 2.5, may be premised on engines that have yet to be fully developed. As long as the PLAAF has only a few dozen J-20s in service, it may make sense to reserve them for hit-and-run tactics and special deep strikes. But as the article in the Diplomat points out, there’s ample evidence the J-20 may be intended to grow into a capable all-rounder that can hold its own in a dogfight. 但是由于雷达吸收材料的范围和类型会影响雷达控制系统,仅凭视觉分析并不能确定飞机的隐身能力。这并没有阻止美国海军陆战队在格鲁吉亚建造一个J-20的全尺寸模型用于研究和训练。龙8国际娱乐空军吹嘘其苏-30侧翼已经在雷达上跟踪到J -20,但由于隐形战斗机在常规飞行中经常使用“卢尼堡透镜”发射器来扩大雷达横截面,从而隐藏其真实隐身能力,因此也很难据此做出推断。 对歼-20的另一个令人困惑的分析是,它还没有像中国人民解放军空军预想的那样配备高推力WS-15涡扇发动机,目前依然使用俄罗斯的AL-31F发动机。就连中国第四代喷气式飞机也因发动机缺陷而遭遇挫败。WS-15能比AL-31FN多产生23%的推力,能使J-20无需依靠燃料吞吐后燃器实现超级巡航,或维持超音速速度。因此,也有对J-20性能的一些更为大胆的预测,如最高速度可达2.5马赫,可能就是基于尚未完全研发成功的发动机。 只要中国人民解放军空军只有几十架在役歼-20战机,他们可能就只能执行游击战术和深度打击。但正如《外交官》杂志上的文章所指出的,有充分的证据表明,歼-20可能会成为优秀的全能型选手,能够在混战中保持自己的优势。  美国雅虎网站读者评论:  译文来源:三泰虎    http://www.santaihu.com/46776.html       译者:Joyceliu  外文链接:https://news.yahoo.com/f-22-f-35-killer-110000559.html ken Canards DO NOT lend themselves towards stealthiness.

The F22 would work it over while the F35 is a 'stand off' weapon. It will interlink with other systems and nail the J20 long before it sees the F35... That is if it every gets completed. Still, 11 prototypes/demonstrators are a long way from fielding and actual airforce. 仅仅因为看起来隐形,并不意味着它就隐形。F22可以解决这个问题,而F35是一种“远程”武器。它可以与其他系统连接,在J20发现F35之前就能锁定J20……如果每件事都完成了。尽管如此,11个原型/模型距离部署和实际空战还有很长的路要走。   Jeffery Yes, the details of the J20 are sketchy, 是的,J20的细节经不起推敲   ΜΟΛΩΝ ΛΑΒΕ For the love of...
