    Abstract: A part is used that constitutes a platform web and that has a shape close to the shape of the platform with an inside face and an outside face that are opposite each other. Fiber reinforcement plies are draped on a blade core and at least some of these plies extend beyond an end of the blade that is to be connected to the platform so as to form ply extensions. The ply extensions are folded down against the inside and outside faces of the platform to form flaps securing the blade to the platform, and fiber reinforcement plies are draped around the platform web and over the flaps so as to form a platform box retaining the flaps.

    Abstract translation: 使用构成平台腹板的部件,其具有接近平台形状的形状,其内表面和外表面彼此相对。 纤维增强层被覆在刀片芯上,并且这些层中的至少一些延伸超出要连接到平台的刀片的端部,以便形成层叠延伸部。 层叠延伸部相对于平台的内侧和外侧面向下折叠以形成将叶片固定到平台的翼片,并且纤维增强层围绕平台腹板和翼片覆盖以形成保持翼片的平台盒。
