The invention relates to a secondary flow guide vane (1) for a turbomachine, comprising skins (2, 3) having ends (21, 31) between which an opening (5) and a cavity (4) are delimited, the skins branching off from each other in a direction (Y). A filling material (41) is located in the cavity (4) at a distance from the opening (5). The density of the reinforcement (6) is higher than the density of the material (41), the reinforcement comprising a first reinforcement portion (61) positioned in the cavity (4) against the material (41) and a second reinforcement portion (62) for closing the opening (5) between the portions (21, 31) to form a unitary piece.
本发明涉及一种用于涡轮机的次级流导向轮叶(1),包括蒙皮(2,3),蒙皮具有端部(21,31),在端部之间界定出开口(5)和空腔(4),蒙皮沿方向(Y)彼此分支。填充材料(41)位于空腔(4)中、与开口(5)相距一距离。增强件(6)的密度高于材料(41)的密度,增强件包括抵靠材料(41)定位在空腔(4)中的第一增强部分(61)以及用于封闭部分(21,31)之间的开口(5)的第二增强部分(62),以形成一体件。
