发明名称 PRELOADED PROPELLER BLADE ASSEMBLY
摘要 A propeller blade assembly (1) comprises a plurality of propeller blades (10) each connected to a hub (2) via at least one bearing assembly (3,4). Each of the blades (10) and the bearing assemblies (3,4) is preloaded, wherein the preload is applied over a preload path which includes a blade root portion (11) of each blade (10) and the bearing assemblies (3,4), and a spring (6) is provided in the preload path. In the event of wear of the components of the propeller blade assembly, the spring (6) maintains the preload force. A method of applying the preload to the propeller blade assembly (1) is also disclosed.
