The invention discloses a flying wing layout backpack type air inlet channel considering both high and low speed performance and stealth performance, which is a parallel double-engine double-S-bend air inlet channel, and comprises an air inlet lip, a lip cover, a middle partition plate, a semi-elliptical throat channel and two S-bend air inlet channels, the front edge of the M-shaped air inlet lip is parallel to the front edge or the rear edge of the wing, the folding point of the M-shaped air inlet lip is located at the circumferential angle of 45 degrees, the outer wall face of the lip cover is in smooth transition with the fuselage, the inner wall face of the lip cover is smoothly connected with the semi-oval throat, and the middle partition plate is arranged on the front sides of the air inlets and provided with a fillet design to divide the semi-oval throat into the two air inlets. The two air inlets correspond to the two S-bend air inlet channels respectively. According to the flying wing layout backpack type air inlet channel, excellent air inlet channel performance and full-aircraft aerodynamic performance can be obtained under different speed domains, and the good stealth capacity is achieved.

    本发明公开了一种兼顾高低速性能和隐身性能的飞翼布局背负式进气道,为并列双发双S弯进气道,包括进气唇口、唇罩、中间隔板、半椭圆形喉道和两个S弯进气道,进气唇口在俯视或仰视方向上呈M型,M型的进气唇口前缘与机翼的前缘或后缘平行,M型的进气唇口折点位于周向角45°,唇罩外壁面与机身圆滑过渡,唇罩内壁面光滑连接半椭圆形喉道,中间隔板置于进气口前侧,具有圆角设计,将半椭圆形喉道分隔成两个进气口,两个进气口分别对应两个S弯进气道。该飞翼布局背负式进气道能够在不同速域下都获得优异的进气道性能和全机气动性能,具备良好的隐身能力。
