[0038] 应了解的是,在若干项实施例中,额外表面部件可施加在或位于接缝上,所述接缝位于叶片部分104、106与连接套管102的末端138、140的接口处,从而确保获得实质上平滑的气动廓线。 [0038] It should be appreciated that, in several embodiments, additional components may be applied to the surface or located on a seam, the seam 104 located at the blade tip portion of the connecting sleeve 102 at the interface 138, 140 to ensure a substantially smooth aerodynamic profile. 例如,在一项特定实施例中,可将若干层薄板复合材料施加在转子叶片组件100的外层周围,例如,使用湿敷工艺,从而在叶片部分104、106和连接管套102之间提供实质上平坦的气动廓线。 For example, in a particular embodiment, the sheet may be several layers of composite material applied around the outer rotor blade assembly 100, for example, wet process to provide a blade portion 104, 106 between the sleeve 102 and the connecting pipe substantially flat aerodynamic profile. [0039] 应理解的是,连接套管102 —般可由任何合适的材料形成。 [0039] It should be understood that the connecting sleeve 102 - as may be formed of any suitable material. 例如,在一项实施例中,连接套管102可由铝、钢等金属形成。 For example, in one embodiment, the connection sleeve 102 may be made of aluminum, steel or the like. 在其他实施例中,连接套管102可由薄板复合材料形成,例如,各种纤维增强复合材料或其他任何合适的非金属材料。 In other embodiments, composite sheet 102 may be connected to the sleeve is formed, e.g., fiber-reinforced composite material or any other suitable non-metallic material. [0040] 现参考图5和图6,附图所示为所公开的转子叶片组件100的两项实施例的局部截面图,尤其图示了第一叶片部分104和第二叶片部分106在连接套管102内的附接。 [0040] Referring now to Figures 5 and 6, a partial sectional view of the embodiment shown in the drawings two embodiments of the disclosed rotor blade assembly 100, particularly illustrating the blade portion 104 and a second portion of the first blade 106 is connected the attachment sleeve 102. 如上所述,叶片部分104、106的连接末端130、131 —般可经配置以在连接套管102所设有的腔136内进行附接,这样就可沿着转子叶片组件100的翼展112 (如图2所示),尤其是在连接套管102的根端138和梢端140与叶片部分104、106的壳体120之间的接口处,形成实质上连续的气动廓线。 As described above, the connecting end portions of the blades 130, 131, 104, 106 - as may be attached within the coupling sleeve 102 is provided with a cavity 136 is configured so that the rotor blade assembly can be along the span of 112,100 (FIG. 2), especially in the root end 102 of the coupling sleeve 138 and the housing 120 at the interface between the tip 140 and blade portion 104, 106, form a substantially continuous aerodynamic profile. 因此,在若干项实施例中,叶片部分104、106各自的截面高度156—般可在连接末端130、131处减小,从而使连接末端130、131插入连接套管102中,并确保叶片部分104、106和连接套管102之间形成实质上连续或平坦的表面。 Accordingly, in several embodiments, the blade portion of each cross section may be reduced as the height of 156- 104, 106 at the connecting end 130, 131, 130, 131, so that the connecting terminal inserted into the connecting sleeve 102, and to ensure that the blade portion and a coupling sleeve 104, 106 form a substantially continuous or flat surface 102 between. [0041] 例如,如图5所示,在一项实施例中,叶片部分104、106的连接末端130、131的至少一部分可形成锥形廓线,例如,将叶片壳120配置成具有逐渐变薄的厚度158,从而使连接末端130、131位于连接套管102中。 [0,041] For example, as shown in FIG. 5, in one embodiment, the connecting end portion 130, 131 at least a portion of the blade 104, 106 form a tapered profile may be, e.g., the blade shell 120 is configured to have a tapered the thickness of the thin 158, 130, 131 are positioned so that the connecting end 102 of the sleeve is connected. 此外,连接套管102可形成对应的锥形廓线,这样,连接套管102的外表面146即可位于实质上与叶片壳120的外表面160齐平的位置。 In addition, sleeve 102 may be connected to form a corresponding tapered profile, so that 146 is connected to the outer surface of the blade is located substantially 160 of the housing 120 flush with the outer surface of the sleeve 102 in position. 因此, 如图所示,连接套管102 —般可在其根端138和梢端140处形成逐渐变窄的宽度162,所述宽度对应于叶片壳120逐渐变薄的厚度158。 Therefore, as shown, is connected sleeve 102 - as may be formed in a gradually narrowed width 162 and tip 138 at its root end 140 of the blade shell 120 corresponding to the width of the tapering thickness of 158. 应了解的是,尽管所示连接套管102逐渐变窄的宽度162显示为在根端138和梢端140处形成实质上的锐边或刃缘,但实际上逐渐变窄的宽度162无需形成此类锐边或刃缘。 It should be appreciated that the connection sleeve 102 tapers in width to form 162 shown in FIG Although shown substantially sharp edges or cutting edge 138 at the root end and a tip end 140, but actually the width of the tapering necessary to form 162 such sharp edges or cutting edge. 例如,在一项实施例中,连接套管102的锥形廓线可经配置以仅部分沿着叶片部分104、106的锥形廓线进行延伸,这样,即可在连接套管102的根端138和梢端140处形成相对较薄的钝缘。 For example, in one embodiment, the connection sleeve 102 may be tapered profile configured to extend only partially along the tapered blade profile portion 104, so that the sleeve can be connected in the root 102 at the tip she ends 138 and 140 forms a relatively thin blunt edge. 在此项实施例中,例如上述薄板层等额外表面部件可施加在根端138和梢端140处,以确保叶片部分104、106和连接套管102之间形成实质上连续的气动表面。 In this embodiment, for example, additional surface layer of the thin plate member and the like can be applied at the root end 138 and tip 140, 104, 106 to ensure that the blade portion and the connecting sleeve forming a substantially continuous aerodynamic surface 102 between. [0042] 或者,如图6所示,叶片部分104、106的连接末端130、131可形成阶梯形廓线,例如,将叶片壳120配置成在连接套管102的根端138和梢端140处的厚度164呈阶梯形减少。 [0042] Alternatively, as shown, connected to the end portions of the blades 130, 131 104, 106 may be formed in a stepped profile 6, for example, the blade shell 120 is configured to connect sleeve 102 to the root end 138 and tip 140 the thickness 164 of the stepped shape is reduced. 在该项实施例中,连接套管102的宽度166实质上等于叶片壳120中所设有的厚度的减少大小,这样,连接套管102的外表面146即可位于实质上与叶片壳120的外表面160齐平的位置。 In this embodiment, the connector 166 of the sleeve 102 is substantially equal to the width of the reduced size of the blade shell 120 is provided with the thickness, so that the outer surface of the sleeve 102 of the connector 146 can be located in the blade case 120 is substantially 160 outer surface flush position. 在其他实施例中,应了解的是,连接套管102和/或叶片部分104、106的连接末端130、131 —般可采用其他任何合适的配置以使连接末端130、131插入连接套管102中。 In other embodiments, it is understood that the connection sleeve and / or blade portions 104, 106 of the terminal 130, 131, 102 - like any other suitable configurations may be employed so that the connector end inserted into the connecting sleeve 130, 131, 102 in.
