枭龙3战机问世后还会如何改进一条鸿沟令其陷入尴尬雷达空军随着大家讨论多年的“枭龙”BlockⅢ战斗机最近终

  随着大家讨论多年的“枭龙”BlockⅢ战斗机最近终于迎来了首飞,虽然这样机上使用的究竟的KLJ-7A有源相控阵机载雷达还是LKF601E型风冷有源相控阵雷达,到现在也无法从极少数的照片里看出个底细,不过对于巴基斯坦空军来说,本国空军战机的相控阵雷达梦。现在看来是快要成真了。

The klj-7a active-phase-control airborne radar or lkf601e air-cooled active-phased-array radar, which has been under discussion for years, has finally made its debut, but for the pakistani air force, the air force has dreamed of a phased-array radar. Now it looks like it's coming true.

  对于“枭龙”战机的升级而言,换装有源相控阵雷达本就是一件意料之中的选择。由于“枭龙”是一款轻型战斗机,在上相控阵雷达这件事上就有了不少的限制。一来飞机本身的起飞重量和机头较小的雷达安装位置,决定了该型雷达的整体尺寸和重量都要受到限制;二来基于一台RD-93中推发动机的推力和发电功率,相控阵雷达可以使用的功率受到了严格限制,雷达的散热系统的复杂程度和能耗也不能太高;总之轻型战斗机上用上个有源相控阵雷达不容易,所以在解决有无问题之余,别的东西就不好奢求太多。

For the upgrading of the \"Owl Dragon\" aircraft, the replacement of active phased array radar is an unexpected choice. Since the \"Owl Dragon\" is a light fighter, on the phased array radar this matter has a lot of restrictions. The overall size and weight of the radar are limited by the fact that the aircraft's take-off weight and the position of the radar with a smaller head determine the overall size and weight of the radar. Second, based on the thrust and power generation power of an RD-93, the power available to the phased array radar is strictly limited, and the complexity and energy consumption of the radar's heat dissipation system cannot be too high.

  当然在“枭龙”Block3的雷达选型上,从一开始就有两个来自中国不同工业系统的产品以供选择——中国电科的KLJ-7A和中航工业的LKF601E。两型雷达在此前都已经进行了装机试验,不过区别在于LKF601E直接装上了较早制造的“枭龙”,而KLJ-7A则之前则被安装在试飞院的一架运-7测试平台上——按照一些相关人员的私下说法,能够装到更加接近于Block3型飞机的“枭龙”上进行测试,这多少能算是做是LKF601E雷达来自“自家人”的一种待遇上的优势。

There were, of course, two products from different industrial systems in China from the start - KLJ-7A in the China Electric Division and LKF601E in the Air China Industry - on the radar selection for \"Owl Dragon\" Block 3. Both radars have been tested before, but the difference is that LKF601E was fitted directly with an earlier-made owl, while KLJ-7A was previously mounted on a test-run platform at the test lab - which, according to some people in private, can be tested on an owl that is closer to the Block3 than it was on the LKF601E radar's own treatment.

  不过对于机载雷达的测试而言,无论测试阶段用的是什么飞机,和装上目标机的状态都会有些差异,而目前试飞的首架“枭龙”Block3使用铝蒙皮和大号空速管的机头,表明虽然雷达的选型未必就还没结束,但至少在这架3000号机目前的试飞阶段,主要进行的还是飞机平台本身在各种设备调整之后的性能试飞。因此我们能够看到除了雷达之外的航电设备发生的明显变化——比如在“枭龙”这样的座舱里显得异常巨大的衍射平显,以及在进气道后方的新型雷达告警设备。

However, for airborne radar testing, no matter what the aircraft is used in the test phase, and the status of the target aircraft will be somewhat different, and the current test of the first \"Owl Dragon\" Block 3 using aluminum mask and large airspeed tube head, indicating that although the radar selection is not necessarily over, at least in the current test phase of the 3000 aircraft, or the aircraft platform itself after the various equipment adjustments in the performance test. So we can see significant changes in avionics other than radar - such as the unusually large diffraction flat-out in cockpits such as \"owls\" and the new radar alarms behind the intake channels.

  对于四代机(就是大家传统的三代机)升级为四代半这件工作而言,其主要的变化大多数都集中在航电设备上,新一代的航电设备比起之前的产品一方面重量上有所增大,另一方由于使用了主动相控阵技术,系统的耗电加大,热量加大,对散热的要求也加大,散热系统消耗的功率也加大,所以回到咱们一开始谈论的东西也就是发动机身上,理论上更大推力的发动机以及更强的发电功能无疑是改进中必须关照的。

For the work of upgrading the four-and-a-half-generation machines (the traditional three-generation machines) to four-and-a-half-generation machines, most of the major changes are focused on avionics, where the new generation of avionics, on the one hand, weighs more than the previous products, and the other uses the active phased array technology, which increases the system's power consumption, demands more heat dissipation, and consumes more power.

  对中国航空工业而言,基于RD-93发动机仿制的涡扇-13发动机虽然并未大批量投产,但在该机基础上研制的增推型号也早就达到了实用状态,完全可用提供给升级型号的“枭龙”使用。但这时候必须承认作为一款外贸战机的配置,用户本身的需求肯定是比技术能力本身更重要的,小巴作为合作开发方本来就没什么钱这事儿也不是一天两天了,所以在研发中尽量少改动设计,同时尽可能沿用巴军现有的装备保障体系,自然是节约资金的巴基斯坦空军所要坚持的。

For china's aviation industry, the rd-93 model of the turbofan-13 engine, though it hasn't been put into production in large quantities, has long been in use and is available to the upgraded \"owl \". But it must be recognized that as a foreign aircraft configuration, the user's own needs are certainly more important than the technical ability itself, the small bus as a co-developer is not a lot of money in a day or two, so in research and development as little as possible to change the design, and as much as possible to follow the existing equipment support system, is naturally the money-saving pakistani air force to insist.

  如此一来,“枭龙”Block3这种换眼不换发的设计,某种程度上就和台军目前升级改进的F-16V(不是后续计划订购的F-16VBlock70/72)一样,是一种相当注重经济性的设计。当然注重经济性就会让实际表现受到一些影响。无论是解放军空军之前在实战化对抗中歼-11/16系列对于歼-10系列在电子对抗中展现出来的功率优势,还是目前使用三代发动机的歼-20在电子战领域因为电力问题受到的掣肘,都充分说明在航电系统的表现上,充沛的能源供给的极端重要性。

Thus, the design of the \"Owl Dragon\" Block 3, which does not change its eyes, is, in part, as economical as the F-16V (not the F-16V Block 70\/72 ordered by the current upgrade). Of course, focusing on the economy will have some impact on actual performance. Whether it is the power advantage of the J-11\/16 series for the J-10 series in the electronic confrontation before the PLA Air Force in actual combat, or the J-20, which currently uses three-generation engines, in the field of electronic warfare because of the constraints on electricity problems, fully illustrates the extreme importance of abundant energy supply in the performance of the avionics system.

  当然从另一个角度来看,即使“枭龙”Block3能够使用更好的发动机,该机在面对同代更大型的中型和重型战机时,依然免不了要处于下风。虽然某种程度上这可以算是必然的结果,但确实对于轻型战斗机的发展而言,如今这个技术前沿从四代机转向五代机的时代里,轻型战斗机的生存空间,似乎已经快要随着时代的演进彻底消失了。

On the other hand, of course, even if the \"Owl Dragon\" Block3 could use a better engine, it would still have to fall in the face of larger medium and heavy fighters of its generation. Although this is somewhat inevitable, it is true that for the development of light fighter aircraft, the survival space of light fighter aircraft seems to be about to disappear with the evolution of the times in the age of the technological frontier from four to five.

  本来在“鹰狮”、“枭龙”等型号面世的时代里,轻型战斗机的生存空间已经相当狭窄,单靠廉价或者单纯的数量已经很难弥补轻型战斗机的性能劣势,而轻型战斗机如果要在性能领域获得均势甚至优势,则必须要有至少半代以上的技术代差(就像之前泰国的JAS-39C在面对解放军的苏-27SK战机的情况一样),“枭龙”Block3虽然哪怕对于苏-30MKI级别的战机都不会屈居下风,但毕竟后者也是十多年前的整体技术了,面对当代技术的战机的时候,轻型战机的这种性能上的“不够用”依然无法扭转。

In the age of the \"lions\" and \"dragons \", the survival space of the light fighters has been quite narrow, and it is hard to compensate for the performance disadvantage of the light fighters on the basis of cheap or simple quantities alone, and if the light fighters are to gain a balance or even advantage in the performance field, they must have at least half a generation of technical differences (as in the case of the previous JAS-39C in Thailand against the PLA's SSK-27).

  至于下一代的五代机,对于轻型战斗机的难度就更加巨大了。毕竟4S的性能要求摆在这里,而其中至关重要的隐身性又要求战机至少要将常用的空战挂载武器全部内置挂载。这就要求战机必须具备能够容纳这些武器的弹舱,而这一结构的出现,自然要让飞机的横截面积出现显著的增长,特别考虑到当代空空导弹为了追求射程加大弹径和弹长,以及空战挂载基本的“2中2近”的数量要求,让五代战机无论如何也没有办法瘦下身来。

As for the next generation of five-generation aircraft, the difficulty for light fighter aircraft is even greater. After all, the performance requirements of the 4S are set here, and the critical invisibility of the 4S requires the aircraft to mount at least all of the commonly used air combat mount weapons. This requires that the aircraft must have a capsule capable of accommodating these weapons, and the appearance of this structure will naturally lead to a significant increase in the cross-sectional area of the aircraft, particularly in view of the fact that contemporary air-to-air missiles have no way of losing weight in the pursuit of a larger range and longer range, as well as the basic number of \"2 in 2 near \"requirements for aerial warfare.

  如此一来,在当代技术水平之下,传统定义上的“轻型战斗机”想要依靠单台的中等推力发动机,在机内设置一个体积不小的弹舱的情况下,取得高机动性能和超音速机动能力,无疑是难上加难,而这一技术鸿沟的难以跨越,某种程度上也就意味着轻型战斗机在未来的尴尬境地。

In this way, at the contemporary level of technology, the traditional definition of \"light fighter\" to rely on a single medium thrust engine, in the case of a small size of the projectile, the acquisition of high maneuverability and supersonic maneuverability, and this technology gap is difficult to cross, to some extent, the embarrassment of the light fighter in the future.
