FLEXBEAM ROTOR ATTACHMENT TO ROTOR BLADE |
摘要 |
A rotor blade assembly includes a flex-beam member and a torque tube surrounding the flex-beam member and extending partially along a rotor blade assembly length. A rotor blade surrounds the flex beam member and extends from the torque tube to a blade tip. A connecting assembly secures the rotor blade and the torque tube at the flex-beam member. The connecting assembly includes a first connecting member extending at least partially into the rotor blade assembly through the rotor blade from a first rotor blade side and a second connecting member located at a second rotor blade side. A clamping load between the first connecting member and the second connecting member secures the rotor blade and torque tube to the flex-beam member. |
