    Studied the X-47B double-swept lfying wing conifguration, and analyzed the inlfuenceof geometric parameter such as leading edge swept angle and the chord length of outboard wing to aerodynamic and stealth characteristic. The reason inboard and outboard leading edges adopting different section shapes was discussed. Finaly summarized the X-47B developing course and the effect of wingtip trimming, giving a reference to aerodynamic and stealth design of lfying wing conifguration.
