<P>PROBLEM TO BE SOLVED: To provide a support ring for a rotary assembly, such as a propeller assembly. <P>SOLUTION: A support ring 30 includes support cups 20 for receiving blade roots of propeller blades. The support cups 20 are interconnected by bridging structures 32. Each bridging structure 32 includes bridging walls 36 which extend radially from a bridging web 38. The bridging structures 32 thus have a channel-shaped cross-section. The bridging walls 36 have a scalloped configuration at their radially outer edges 40. As a result of this configuration, the neutral axes of the bridging structures 36 are straight, so that the support ring 30 behaves, in structural terms, as a polygon. <P>COPYRIGHT: (C)2013,JPO&INPIT |
