The invention relates to a leading edge structure for a high-speed pneumatic aircraft, in particular to a V-C leading edge structure of a ceramic matrix composite assembly. The technical problems that an existing leading edge assembly for the high-speed pneumatic aircraft is prone to hot cracks and fatigue failure, large in weight and difficult to install and connect are solved. The leading edge structure comprises a leading edge component of a V-shaped structure, a leading edge beam component and two leading edge beam base plates, wherein the leading edge beam component and the two leading edge beam base plates are arranged in the V-shaped structure and below the V-shaped structure respectively; the front edge beam component comprises a first front edge beam and a second front edge beam which are arranged back to back; the two side faces of the first front edge beam and the two side faces of the second front edge beam are attached to the two inner side faces of the V-shaped structure correspondingly, and the outer end of the second front edge beam extends out of the V-shaped structure. The inner ends of the two front edge beam base plates are attached to the opening end face of the V-shaped structure respectively, the inner side faces of the two front edge beam base plates are attached to the two outer side faces of the second front edge beam respectively, and the inner side of the second front edge beam is connected with a framework of the aircraft.

    本发明涉及一种用于高速气动飞行器的前缘结构,具体涉及一种陶瓷基复合材料组件V‑C前缘结构。解决了现有用于高速气动飞行器的前缘组件,存在易发生热裂纹和疲劳失效、重量大、安装连接困难的技术问题。本发明前缘结构包括V形结构的前缘构件,分别设置在V形结构内和V形结构下方的前缘梁构件和两个前缘梁垫板;前缘梁构件包括背靠背设置的第一前缘梁和第二前缘梁;第一前缘梁和第二前缘梁的两个侧面均分别与V形结构的两内侧面贴合,且第二前缘梁的外端延伸出V形结构外;两个前缘梁垫板的内端分别贴合在V形结构开口端面上,两个前缘梁垫板的内侧面分别贴合在第二前缘梁的两个外侧面上,第二前缘梁的内侧与飞行器的骨架连接。
