DSI进气道(英语:Diverterless supersonic inlet,即无附面层隔道超音速进气道)或蚌式进气道是一种运用于现代战斗机上的发动机进气道。DSI进气道通常由鼓包和向前延伸的进气整流罩组成。DSI进气道中鼓包可作为一个压缩面,当空气进入时使空气减速并增大压力,并使得空气得以在整流罩一侧进入进气道。传统的超音速飞机一般采用进气坡道或者进气锥技术。与传统的进气道相比,DSI进气道结构更简单、重量较小且具有更好的匿踪性能。[1]

研发历史

洛克希德·马丁公司于1990年代开始从事DSI进气道相关方面的研究工作。1996年12月11日,世界上首架装有DSI进气道的F-16试验机首飞成功。这架F-16战斗机实现了2.0 马赫的飞行速度,且操控性能与原版的F-16战斗机相当。甚至在亚音速下的一些性能也得到了提高。后来,这种进气道被用于洛克希德·马丁公司生产的F-35战斗机中,于2015年服役[1]

使用DSI进气道的F-35

中国成都飞机公司巴基斯坦航空综合企业英语Pakistan Aeronautical Complex开发的枭龙战机是第一种投入服役的使用DSI进气道的战斗机,于2007年服役。另外中国的歼-35歼-20歼-10B/C教练-9G也使用了DSI进气道。[2]
