  • Coupling part structure for vane and jet engine including the same
    Patent number: 9963986
    Abstract: A coupling support member including a pair of divided pieces is placed between an end portion of a guide vane and an attachment flange, and the pair of divided pieces is joined to the vane end portion from both sides in the vane thickness direction. A linear protrusion is formed on one of joint surfaces of the vane end portion. A groove engaged with the linear protrusion is formed in one of respective joint surfaces of the pair of divided pieces. The vane end portion is fastened between the pair of divided pieces. It is possible to obtain a high structural strength while contributing to a reduction in weight of a jet engine.

  • Molded part
    Patent number: 9739175
    Abstract: An additional pad 27 is additionally and integrally arranged from an outer surface of a flange 17 opposite to a contacting side of the flange 17 to a small-diameter curved surface of a bend 19 and from there to an end of an outer surface of a part body 13. On an outer surface side of the additional pad 27, a fastening seat 27f is formed by machining. An area end PAe of a processed area PA formed by machining is positioned on the part body 13 beyond the bend 19.

  • COUPLING PART STRUCTURE FOR VANE AND JET ENGINE INCLUDING THE SAME
    Publication number: 20150064000
    Abstract: A coupling support member including a pair of divided pieces is placed in a coupling part between a vane proximal end portion of a guide vane and an attachment flange, and the pair of divided pieces are joined to the vane proximal end portion from both the sides in the vane thickness direction. A linear protrusion is formed on one of joint surfaces of the vane proximal end portion to the pair of divided pieces. A groove engaged with the linear protrusion formed in the vane proximal end portion is formed on one of respective joint surfaces of the pair of divided pieces of the coupling support member. The vane proximal end portion is held between the pair of divided pieces of the coupling support member, by the fastening force that is applied to the pair of divided pieces of the coupling support member from both the sides in the vane thickness direction. It is possible to obtain a high structural strength while contributing to a reduction in weight of a jet engine.
