US Patent 10236590 Foldable segmented structure and deployable reflector antenna comprised thereof

A foldable segmented structure includes a substantially center portion and a plurality of strut assemblies radially disposed around the center portion. Each strut assembly includes an inner and outer strut. The inner strut includes a first end portion rotatably coupled at the center portion and a second end portion rotatably coupled to the outer strut at an intermediate portion of the strut assembly. The intermediate portion is spaced apart from the center portion. At least one shell segment is disposed on at least one of the inner and outer strut. Each inner strut is configured to rotatably articulate about the first end portion in a first angular direction. Each outer strut is configured to rotatably articulate about the second end portion in a second angular direction opposite to the first angular direction to form an axially extending structure from the center portion to the intermediate portion in a stowed configuration.
