The invention discloses a gaseous fuel header pipe structure and a gas turbine engine, the fuel header pipe structure comprises a gas transmission main pipe body which is spirally arranged in the axial direction, the gas transmission main pipe body comprises an arc pipe, and the two ends of the arc pipe communicate with a first gas transmission pipe and a second gas transmission pipe correspondingly; the ends, away from the arc pipe, of the first gas conveying pipe and the second gas conveying pipe are blocked. A plurality of first branch pipes are arranged on the inner side of the first gas conveying pipe in the arrangement direction of the first gas conveying pipe at intervals in a communicating mode, and the first branch pipes are arranged in the radial direction of the arc pipe. A plurality of second branch pipes are arranged on the inner side of the second gas conveying pipe in the arrangement direction of the second gas conveying pipe at intervals in a communicating mode, and the projection of the second branch pipes in the axial direction is overlapped with the first branch pipes at the corresponding positions. An air inlet pipe is arranged on the outer side of the arc pipe in a communicating mode and arranged in the radial direction of the arc pipe. The non-uniformity of the flow of the gaseous fuel can be reduced on the basis that the pipe diameter of the gas transmission main pipe body does not need to be increased.

    本发明公开了一种气态燃料总管结构及燃气涡轮发动机,其中燃料总管结构包括沿轴向呈螺旋状布置的输气主管体,输气主管体包括圆弧管,圆弧管的两端分别连通有第一输气管和第二输气管,第一输气管和第二输气管背离圆弧管的一端均封堵设置;第一输气管的内侧上沿第一输气管的布置方向间隔连通设置有多个第一支管,第一支管沿圆弧管的径向布置;第二输气管的内侧上沿第二输气管的布置方向间隔连通设置有多个第二支管,第二支管沿轴向的投影与对应位置的第一支管相重叠;圆弧管的外侧连通设置有进气管,进气管沿圆弧管的径向布置。本发明能够实现在无需增大输气主管体的管径的基础上降低气态燃料流量的不均匀度。
