摘要： An FRP material has a circular arc part, and a member fixed to the circular arc part. The FRP forming system has a portion-pressing device, a member positioning mechanism, and a transport device configured to form the FRP material as a single body of a circular arc-shaped FRP part. The FRP material may comprise a single layer prepreg or a plurality of prepregs that have been layered. The portion-pressing device has upper and lower molds sandwiching a portion of the FRP material in a radial direction orthogonal to the circular arc part, and compresses intermittently a portion of the FRP part. The member positioning mechanism locates the position of the member relatively to the upper or lower mold. The transport device moves the portion of the FRP material that is compressed by the portion-pressing device. The portion-pressing and the transport are repeated to form the FRP part.

摘要： 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 groove is formed in one end portion joint surface of the coupling support member, a linear protrusion is formed on the other end portion joint surface, the vane proximal end portion is formed into a concavo-convex shape, a linear protrusion that is engaged with the groove which is formed in the end portion joint surface is formed on a joint surface to the one end portion joint surface, a groove that is engaged with the linear protrusion formed on the end portion joint surface is formed in the joint surface to the other end portion joint surface. 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 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.
摘要翻译：包括一对分割片的联接支撑构件被放置在导向叶片的叶片近端部分和附接凸缘之间的联接部分中，并且一对分开的片从两侧分别接合到叶片近端部分叶片厚度方向。在联接支撑构件的一个端部接合表面中形成有一个槽，在另一个端部接合表面上形成一个直线突起，该叶片的基端部形成为一个凹凸的形状，一个与形成在端部接合面的槽形成在与一端部接合面的接合面上，与端部接合面上形成的线状突起配合的槽形成在接合面上端部接合面。通过从叶片厚度方向的两侧施加到联接支撑构件的紧固力，叶片近端部分保持在联接支撑构件的一对分割片之间。可以获得高结构强度，同时有助于减少喷气发动机的重量。

摘要： A blank sheet including a plurality of main fibers arranged in parallel with each other, auxiliary fibers and a resin that consolidates the fibers is heated to a temperature at which the resin softens, and then pressed against a fan blade mold with the direction of the main fibers aligned with the longitudinal direction of the fan blade mold. The fan blade mold is shaped so that the length thereof in the longitudinal direction along the surface of a center part thereof in the width direction is shorter than the length thereof in the longitudinal direction along the surface of end parts thereof in the width direction. When the blank sheet is pressed against the fan blade mold, a center part in the width direction of the blank sheet at an end part in the longitudinal direction is pulled with a greater force than end parts in the width direction of the blank sheet at the end part in the longitudinal direction, thereby preventing occurrence of wrinkling.
