轟20核心技術已被列出,5大項目已完成4項,中國軍工只差最後一步

由于可以改变现代化战争的“游戏”规则,几乎所有国家的空军力量都想拥有大型战略轰炸机。目前,大型战略轰炸机具体有两种类型,第一种最具代表的便是俄罗斯的图-160超音速战略轰炸机,第二种则是美国的B-2隐形战略轰炸机。中央电视台披露了关于H-20的消息,称它已经取得了巨大的进步。一架轰-20型战机在航空业的宣传片《大国起飞》中亮相。另外,航空工业西飞一飞院还专门建立了用于轰20进行大型试验的平台,这同时也预示着轰-20的即将到来。轰20核心技术已被列出,5大项目已完成4项,中国军工只差最后一步

大型战略轰炸机的技术比J-20更先进。事实上,根据此前军方的具体分析,轰-20隐身远程战略轰炸机项目要想取得成功,至少需要满足五大核心技术要求。总的来说,我们已经突破了前四项,只差最后一步!其中之一是大型飞翼的整体布局。从此前中航工业曝光的THE NEXT图中不难分析,轰20类“风筝”式的飞翼设计没有任何的多余,这是对其动力设计和计算机模拟的很大考验,而这种设计实际已经在我国无人机“攻击11”上出现。不难分析,轰20的设计结构一定会好过B-2,将具备超音速飞行能力,所以才导致目前的气动设计费时费力,并需要进行大量的风洞试验验证。

第二项为飞行控制软件领域的技术。以美军的B-2为例,这样的大型飞翼布局实际上就是超临界飞机。在翼身和气动的高度结合下,机身便成为了升力面的一部分。在不同速域进行巡航时,如何保持气流集中,无尾翼设计转向翼尖不失速成为了要研究的问题,这也是传统四代机不能靠静态稳定飞行来控制战机改变飞行姿态的原因。这就意味着飞行控制技术需要4次以上的冗余数字电传,传感器的灵敏度,飞行控制算法的编写,对飞控软件的要求非常高,不过我国目前的飞控软件技术已经实现突破性进展,用于轰-20应当不是问题。其次便是全隐身喷涂技术,其实中国这方面的技术已经突破,歼-20已经实现。实际上,即使歼-20的鸭翼与主翼边缘完全对称,隐形战机仍然主要依靠几何形状,然后用锯齿来减少反射。歼击机的隐身涂层通常很薄,只有几毫米厚,这样可以保持机动性并减少飞行重量。而第四个核心便是S隐身式进气道,其实这个技巧本身并不罕见。由于飞翼轰炸机的进气系统和喷嘴都是从尾部直转,被称为“背负并排大S进气口”,因此技术难度更大。不过此前,我国央视便曝光我们已经解决”背腹式并列双发S弯进气道”这一关键技术,和美军的B-2达到同一水平。.轰20核心技术已被列出,5大项目已完成4项,中国军工只差最后一步

最后一步便是我国航空技术长期以来的“心病”——发动机。参照美军B-2装备的4台F118发动机来看,轰20备选的发动机WS10,WS15,WS18,WS20。大涵道比的WS20并不是首选,而小涵道比发动机WS10更为成熟也更有利于轰20的隐身。当然,至于最终的选择还需要我们拭目以待,轰20所发挥的战略价值绝对值得花费大量的人力、物力、财力去慢慢研究,相信我国军工将很快将最后一步完成。
