土豪投70亿助中国造五代机 FC31密集试飞将定型出口

“歼-31”的密集试飞 是否代表其未来能够上舰呢?“歼-31”的密集试飞 是否代表其未来能够上舰呢?

  近日,一组被大家昵称为“歼-31”的中国自行研制的第五代验证机的02机频繁试飞画面引起了引发关注。尤其是这架试飞的02机上明显可以看出机头采用了隐身雷达罩锯齿结构,虽然还有空速管,但是已经非常明确的对外宣称这是要更换相控阵雷达的节奏。这也引发热议,因为很多分析人士都认为,“歼-31”是中国北方飞机企业自行筹资建造的一款验证机,仅作为飞行技术验证使用。而现在密集试飞,正恰逢中国的001A型航母下水,002型航母按道理来说应该即将在船台上现身的时刻,由于普遍判断002型航母将会配备弹射器。这也不仅让人怀疑,“歼-31”此举是真的是为上航母做准备,一款中型、双发、常规布局的战机上航母真的有戏?

现在试飞这架02机,主要改进还是雷达和垂尾两大部分现在试飞这架02机,主要改进还是雷达和垂尾两大部分

  这需要从头开始分析,俗称“歼-31”的战机,正式出口名称为FC-31,而且仅仅有这么一个名字,”歼-31“不过是大家约定俗成的一个名字。由于其并未获得军方注资,因此”歼-31“这个代号目前是不存在的。不过,”歼-31“作为一款由中国航空企业自行投资研发的验证机,其从首架验证机在珠海航展之后就引起了诸多关注,尤其是国外市场,对于这样一款具备能够跟美军新一代五代机F-35在某些领域相抗衡的,中低端价位的第五代战斗机非常感兴趣,这其中就包括了曾经被大家称之为”顶级土豪国家“的沙特阿拉伯。

自从珠海航展上惊鸿一瞥后 “歼-31”一直并不怎么高调自从珠海航展上惊鸿一瞥后 “歼-31”一直并不怎么高调

  沙特阿拉伯看中”歼-31“并非是简单的只是为了买来作为空军战机使用,而有更全长远的考虑,对”歼-31“该型战机来说,中国比美国所能提供的最有诱惑力的选项:就是在中国能够生产、出口,相应的全套配套,航空电子,武器弹药等附属子系统。甚至,可以把整机组装线转移到用户国内,”枭龙“战斗机就是最佳例证。根据俄罗斯《军工信使》报在4月初发布的消息称,沙特阿拉伯或已经投入巨资,资助中国的”歼-31“战机的下个阶段研制。俄罗斯方面估计,总投资高达10亿美元(折合人民币近70亿元)。不过这应该是项目预计总投资,初期不会一口气投入这么多。

沙特非常看重武器出口 并希望获得全套技术沙特非常看重武器出口 并希望获得全套技术

  沙特作为一个资源出口型国家,长期以来,由于充沛的自然资源使得其国家的经济总量成长非常迅速,但是沙特目前也面临很大的出口难题,尤其是在资源市场并不警惕之后,沙特必须寻找进一步能够维持国家根本经济基础的新兴产业。而军事武器出口产业,则是沙特现如今看中的最关键出口增长点。尤其是沙特的新任防大臣穆罕穆德·本·撒勒曼副王储到任之后,对于国防生产出口作为最优先发展项目。之前,沙特从中国引进了包括“彩虹”系列无人机的全套组装线,而且沙特也成为了该地区“彩虹”无人机的一级分销商,这使得沙特仅花了10亿美元的代价,就为自己培养了一个未来拥有良好出口前景的国防出口项目。

  也因为看到中国有意出口更多国防产品,才促使沙特可以进一步注资到中国军工企业中。而且,中沙之间良好的合作关系,也是沙特对中国颇为放心的一个主要重点。根据2017年到现在的不完全统计,中沙之间仅防务装备出口合同就达20亿美元!更不要说沙特曾经从中国花了35亿美元购买了东风-3中程弹道导弹。在中国军工屡获得沙特这样的土豪客户的大订单的背后,是中国军工的长期经营的结果。尤其是中国甚至在沙特提供全套的技术保障团队,根本不用用户自己维护。这也就是为什么沙特跟中国合作如此长时间的真相。

中国甚至出口了“东风-3”中程导弹给沙特中国甚至出口了“东风-3”中程导弹给沙特

  但是,一家欢喜几家愁,中国赚到了,最不乐意的自然就是美国。美国原本指望沙特这颗摇钱树,能够尽可能的提供更多的军火大单。但是美国又频繁的对沙特采购更多的武器加以限制,这使得沙特发觉,美国盟友并不是那么“铁”;还有个不高兴的就是俄罗斯,俄罗斯原本希望能够挤入沙特的防务市场,争取更多订单,但是俄罗斯能提供的中国都有,而且更便宜。这也使得俄罗斯很难插足到沙特的市场。

但是“歼-31”能否上舰 现在是个未知数,尤其是现在仅有2架原型机可用但是“歼-31”能否上舰 现在是个未知数,尤其是现在仅有2架原型机可用

  这样的市场前景和用户的提前认可,让我们对“歼-31”未来的发展为之一振。不过,我们也要充分认识到,五代机的试飞的艰难,歼-20为了完成定型试飞,一共建造了10架之多,连T-50都建造了8架,而“歼-31”目前仅有2架,所以距离最终定型、量产、交付用户仍需很长的时间。至于,“歼-31”是否能够通过沙特的注资角逐航母舰载机这块更大的蛋糕,恐怕也很难,最主要是陆基战斗机和海基战机的设计、材料、制造技术大不相。所以,“歼-31”眼下的工作,还是尽快完成定型试飞,顺利出口才是第一要务。(作者署名:无名高地)
