高超声速武器让战争进入“读秒”时代

2017-05-05 14:20:56   解放军报

一是吸气式高超声速巡航飞行器,典型代表是美国“乘波者”X-51A,俄罗斯“彩虹-D2”飞行试验器。这种吸气式高超声速飞行器通常以超燃冲压发动机为动力,可由飞机、舰艇等平台发射,飞行速度3-10马赫,飞行距离几百至几千千米,可实现临近空间高超声速巡航。

X-51A由美国国防高级研究计划局(DARPA)主导研发,目前已进行了4次飞行试验,前3次因技术原因失败。第四次试验中,超燃冲压发动机工作210秒,飞行距离426千米,最大速度5.1马赫,试验获得成功。虽然X-51A的试验成功率不足50%,但这种超燃冲压发动机推进技术为高速巡航导弹的研发提供了更大可能性。

俄罗斯的高超声速武器技术是在原苏联的冲压发动机技术基础上发展起来的,先后开展了“冷”“彩虹-D2”和“针”等高超声速武器研制。“彩虹-D2”飞行器采用机载发射方式,由图-160M、米格-31等飞机在15-20千米的高度加速到2马赫以上,然后与载机分离,超燃冲压发动机点火工作,开始高超声速巡航飞行。

二是高超声速助推滑翔导弹,典型代表是美国的“FALCON”计划和“常规打击导弹”计划。这种导弹把火箭助推与高超声速滑翔技术相结合,其弹道与传统洲际导弹完全不同,具有极高突防能力,可用于全球常规快速打击。

HTV-2是“FALCON”计划的子计划,为无动力再入滑翔高超声速飞行器,设计时速可达20马赫以上。HTV-2先后在2010年和2012年进行两次试飞,虽因遥测数据出现中断和防热材料剥蚀速率超出设计指标等原因宣告失败,但采集到了超过9分钟的试验数据。

三是小型空天飞机,典型代表是美国的X-37B。这种飞行器具有适应在稀薄大气层飞行的高升阻比气动布局,能够依靠很高的再入速度,在临近空间作高超声速远距离滑翔甚至跳跃式的机动飞行,最大飞行速度可达20马赫,飞行高度在30-100千米。

X-37B由“宇宙神-5”运载火箭发射入轨,已完成四次轨道试验,目前仍在轨飞行。X-37B飞行试验充分验证了其长期在轨飞行、轨道机动、自主返回等方面的优势,被认为是未来太空战斗机的雏形。

随着高超声速武器的不断涌现,我们有理由相信,战争的“读秒”时代已不再遥远。(国防大学 李准)
