PROBLEM TO BE SOLVED: To provide a scramjet engine having improved efficiency, and a flying object.SOLUTION: A scramjet engine 3 includes: a flow passage formation surface 7A configured to form a combustion flow passage 12 from a suction side to an exhaust side via a combustion region; a fuel injection unit 8 configured to inject fuel from the flow passage formation surface 7A on an upstream side of the combustion region; and a lamp unit 9 provided on an upstream side of the fuel injection unit 8, having a concave surface 91 connected to the flow passage formation surface 7A and extending in a curved manner so as to separate from the flow passage formation surface 7A toward a downstream side.SELECTED DRAWING: Figure 2
【課題】効率の向上したスクラムジェットエンジン、飛しょう体を提供する。【解決手段】スクラムジェットエンジン3は、吸気側から燃焼領域を経て排気側へ至る燃焼流路12を形成する流路形成面7Aと、燃焼領域の上流側で、流路形成面7Aから燃料を噴射する燃料噴射部8と、燃料噴射部8の上流側に設けられ、流路形成面7Aに接続されて下流側に向かうに従って流路形成面7Aから離れるように曲面状に延びる凹曲面91を有するランプ部9と、を備える。【選択図】図2
