Abstract:
A flying structure, comprising:first and second structures, each of the first and second structures comprising:an enclosed resilient frame member having a folded and an unfolded orientation, the frame member being coilable and having a natural bias which biases it to the unfolded orientation; anda sheet material partially covering the resilient frame member when the frame member is in the unfolded orientation;a connector having a first end attached to the first structure and a second end attached to the second structure; andwherein the first structure may be placed on top of the second structure when their frame members are in the unfolded orientation to form a stack of first and second structures, and wherein frame members of the stack of first and second structures may be twisted and folded to form a plurality of concentric loops in the folded orientation of the frame members to substantially reduce the sizes of the first and second structures, with the natural bias operating to cause the frame member to spring open to the unfolded orientation when the frame member is unfolded from the folded orientation.
