一种叶片,包括纤维增强件(200),纤维增强件(200)具有由基体致密化的三维织物,所述纤维增强件(200)在单一的编织件中包括根部部分(212)和气动外形部分(211),气动外形部分(211)沿纵向方向(DL)在根部部分与叶片尖端部分(211d)之间延伸,以及沿横向方向(DT)在前缘部分(211a)与后缘部分(211b)之间延伸。气动外形部分(211)包括第一和第二压力侧表面和吸入侧表面(211e、211f)。纤维增强件包括在纤维增强件内侧形成壳体(206)的分隔部(103),填充有成形泡沫(60)的囊(50)存在于该壳体中。分隔部(103)在纤维增强件(200)的气动外形部分(211)内侧的沿纵向方向在根部部分(212)与叶片尖端部分(211d)之间,沿横向方向在前缘部分(211a)与后缘部分(211b)之间的一分隔区域上延伸,分隔部(103)还通向该纤维增强件的气动外形部分的外侧。

    A blade includes a fibrous reinforcement having a three-dimensional weave densified by a matrix, the fibrous reinforcement including, in a single woven piece, a root and an aerodynamic profile part extending along a longitudinal direction between the root part and a blade tip portion and along a transverse direction between a leading and a trailing edge portion. The profile part includes first and second suction side and pressure side faces. The fibrous reinforcement includes a separation forming a housing inside the fibrous reinforcement, a bladder filled with a shaping foam being present in the housing. The separation extends over a separation zone inside the profile part of the fibrous reinforcement comprised between the root part and the blade tip portion in the longitudinal direction and between the leading and the trailing edge portion in the transverse direction. The separation opens to the outside of the profile part.
