Spinner shaft attachment

A propeller assembly comprising:

• a propeller shaft;
• a propeller hub, the propeller shaft being configured to drive rotation of the propeller hub about an axis;
• a plurality of propeller blades mounted to and extending outwardly from the propeller hub;
• and
• a spinner assembly including:
• a cone-shaped member having a plurality of blade openings, the cone-shaped member being coupled to the propeller shaft at a first connection adjacent a first side of the propeller hub;
• a bulkhead frame connected to the cone-shaped member;
• and
• at least one strut configured to couple the bulkhead frame to the propeller shaft at a second connection adjacent a second side, opposite to the first side, of the propeller hub, the at least one strut comprising at least one arm having a longitudinal rigid member and at least one flexure region that defines an axis about which the at least one arm may flex, wherein the at least one flexure region includes a first flexure region formed adjacent a first end of the at least one arm and a second flexure region formed adjacent a second end of the at least one arm.

A spinner assembly comprising:

• a cone-shaped member having a plurality of blade openings, the cone-shaped member being receivable about a shaft at a first location;
• a bulkhead frame connected to the cone-shaped member;
• and
• at least one strut configured to couple the bulkhead frame to the shaft at a second location, the at least one strut including at least one arm having a longitudinal rigid member and at least one flexure region that defines an axis about which the at least one arm bends, wherein the at least one arm includes a first arm and a second arm.
