有消息稱試飛成功並已經定型的飛豹7B採用了DSI
但無法證實這些非官方披露的消息是否屬實,可能要過一段時間才知

Rampless Inlet

The J-10B features a chin-mounted diffuser supersonic inlet (DSI) air inlet. The traditional rectangle-shape air inlet on the J-10 requires a large moveable inlet ramp to generate a rearward leaning oblique shock wave to aid the inlet compression process. The ramp sits at an acute angle to deflect the intake air stream from the longitudinal direction. The air inlets comprises many moving parts, which increases the aircraft’s weight and radar reflections.

The newly designed rampless inlet, first tested on the FC-1/JF-17 fighter design by Chengdu, employs a one-piece bump at the top of the inlet replacing the movable ramp. This eliminates all moving parts on the inlet, lightening the overall weight and reducing the aircraft’s radar signature.

其實殲8都可以改用DSI,咁回好得多.
問題是,DSI造成的高速性能損失,是需要透過加強
發動機推力去彌補

殲-8是高空高速攔截機,不適合使用DSI
