The invention belongs to the technical field of aero-engines, and particularly relates to a hinge type mounting structure of a jet device. The jet device (A) comprises a fixed mounting end fixedly connected with the wall surface of an air inlet channel (C) and an auxiliary mounting end which stretches across the air inlet channel (C) and is flexibly connected with the other wall surface of the air inlet channel (C); the mounting structure comprises a first spherical boss (1), a second spherical boss (2) and a third spherical boss (3), the second spherical boss (2) is positioned on the wall surface of the air inlet channel (C); the two ends of the sleeve are provided with sleeve cavities which are arranged on the first spherical boss (1) and the second spherical boss (2) in a sleeved mode respectively. And when the jet device works, the jet device can be freely contracted, and overlarge stress caused by inconsistent thermal expansion is avoided.

    本申请属于航空发动机技术领域,特别涉及一种射流装置铰链型安装结构,射流装置(A)包括与进气道(C)壁面固定连接的固定安装端以及横跨进气道(C)与进气道(C)另一壁面柔性连接的辅助安装端;所述安装结构包括:位于射流装置(A)的辅助安装端的第一球形凸台(1);位于进气道(C)的壁面的第二球形凸台(2);以及套筒,所述套筒的两端具有分别套在第一球形凸台(1)与第二球形凸台(2)的套腔;套腔与相对运动具有预设阻尼当射流器工作时,射流器可以自由收缩,避免因热膨胀不协调而产生过大的应力。
