| description | PROBLEM TO BE SOLVED: To place blades the structure of which can be broken down into at least two parts while exhibiting a reliable mechanical behavior.SOLUTION: A blade 10 comprises: a structure 20 with aerodynamic profile and including two opposite skins 21, 22 fabricated by three-dimensional weaving of a fibrous reinforcement densified by a matrix, and a longeron 30 including a fibrous reinforcement fabricated by three-dimensional weaving and densified by a matrix, the longeron 30 including a first part 31 extending outside the structure with aerodynamic profile and designed to be connected to a drive hub for rotating the blade and a second part arranged inside the structure 20 with aerodynamic profile between the two skins 21, 22.SELECTED DRAWING: Figure 1
【課題】少なくとも２つの部分に分解することができると同時に、信頼性のある機械的挙動を示す構造のブレードを設置する。【解決手段】空気力学的プロファイルを有する構造体であって、マトリックスによって緻密化された繊維強化材の三次元製織によって作製された２つの対向する外板２１、２２を備える構造体２０と、三次元製織によって作製され、マトリックスによって緻密化された繊維強化材を備える縦通材３０であって、前記空気力学的プロファイルを有する構造体の外側に延在し、ブレードを回転させる駆動ハブに接続されるように設計された第１の部分３１、および空気力学的プロファイルを有する構造体２０の内部で２つの外板２１、２２間に配置される第２の部分を備える縦通材３０とを備えるブレード１０。【選択図】図１ |
