Support ring for a rotary assembly |
摘要 |
A support ring for a rotary assembly such as a propeller assembly includes support cups for receiving blade roots of propeller blades. The support cups are interconnected by bridging structures. Each bridging structure includes bridging walls which extend radially from a bridging web. The bridging structures thus have a channel-shaped cross-section. The bridging walls have a scalloped configuration at their radially outer edges. As a result of this configuration, the neutral axes of the bridging structures are straight, so that the support ring behaves, in structural terms, as a polygon. |

1. A support ring for a rotary assembly, the support ring comprising a ring body having a circumferential array of support cups interconnected by bridging structures, the support cups opening at a radially outer face of the support ring and each bridging structure having a channel-shaped cross-section comprising axially spaced apart bridging walls which extend outwardly, with respect to the ring axis, from a bridging web, wherein each support cup has a radially inner end wall which lies substantially in the same circumferential plane as the bridging webs. |
