Summary:PURPOSE: An aerodynamic blade attachment device for a bearingless rotor of a helicopter is provided to enable the attachment of a rotor blade by detachably arranging a joint part between an airfoil blade and a flexible beam/cuff. CONSTITUTION: An aerodynamic blade attachment device (1) a bearingless rotor of a helicopter comprises an airfoil blade (2), a flexible beam, a control cuff (4), and a joint part. The airfoil blade has a tip end portion and a root end portion. A pitch shaft is formed from the tip end portion to the root end portion. The control cuff surrounds main parts of the flexible beam and is extended along the main parts. The joint part is detachably formed between the control cuff and the root end portion of the airfoil blade and has removable fasteners and a fairing unit (10) for surrounding the flexible beam. The removable fasteners fasten the root end portion of the airfoil blade and the control cuff to the flexible beam.
