摘要： A rotor blade comprises a blade portion, a root portion (30) connected with, and extending from, the blade portion, the root portion (30) having an annular cross section which defines first and second root surfaces, and a plurality of discrete root fittings (31) connected with respective portions of the root portion (30), and adapted for attachment to a blade mounting. Each root fitting comprises an elongate body member (31) which extends from a free end of the root portion (30) towards the blade portion, which defines first and second bonding surfaces, adhesively bonded to the first and second root surfaces respectively, and which includes means for attachment to a blade mounting.

摘要： A rotor blade comprises a blade portion and a root portion extending from the blade portion to a free end for attachment, in use, to a blade mounting. The root portion comprises a plurality of apertures. Each aperture has a bore extending through the thickness of the root in a direction extending substantially perpendicular to the longitudinal axis of the root portion. The rotor blade further comprises a plurality of discrete root fittings, each associated with one of the apertures, for attachment to a blade mounting. Each root fitting comprises an elongate member which extends from a first end, proximal to the free end of the root portion and for attachment to a blade mounting, to a second end which is located within the respective aperture of the root portion. Each root fitting further comprises a barrel shaped and dimensioned to be received within the respective aperture of the root portion. The axial direction of the barrel being substantially aligned with the bore of the aperture. The barrel having a transversely extending bore through which the elongate member extends. Each root fitting further comprises a first tensioning fastener arranged to engage the second end of the elongate member. The aperture is sized and dimensioned such that the second end of the elongate member may project beyond the barrel and be engaged by the first tensioning fastener located within the aperture.
摘要翻译：转子叶片包括叶片部分和从叶片部分延伸到自由端的根部，用于在使用中附接到叶片安装。根部包括多个孔。每个孔具有沿基本上垂直于根部的纵向轴线延伸的方向延伸穿过根部的厚度的孔。转子叶片还包括多个离散的根部配件，每个与其中一个孔相关联，用于连接到叶片安装件。每个根部配件包括细长构件，该细长构件从第一端部延伸到靠近根部部分的自由端并且用于附接到刀片安装件，位于位于根部部分的相应孔口内的第二端部。每个根部配件进一步包括一个桶形和尺寸设计成容纳在根部的相应孔内。筒的轴向方向基本上与孔的孔对准。筒体具有横向延伸的孔，细长构件穿过其延伸。每个根部配件还包括布置成接合细长构件的第二端的第一张紧紧固件。孔的尺寸和尺寸使得细长构件的第二端可以突出超过筒并且由位于孔内的第一张紧紧固件接合。
