Abstract: A doubly curved reflector for compact storage in a folded state includes a plurality of gores, each gore having on either long side a gore side curve. At least one hinge is mechanically coupled between each adjacent gore, the at least one hinge including a fold roll hinge or a living hinge. In a stowed doubly curved reflector state each gore folds about the at least one hinge when folded closed such that a face surface of each gore folds against an adjacent face surface of another gore into a substantially cylindrical structure. In a deployed doubly curved reflector state, each hinge. A doubly curved reflector for compact storage in a folded state and a locked open state, a method of manufacture, and a method for designing a substantially wrinkle free doubly curved foldable reflector having gores of a composite material are also described.

Abstract: A deformable hybrid inflatable boom includes an inflatable tube of a first material having an inflatable tube surface and an inflatable tube longitudinal boom direction in a hybrid inflatable boom inflated state. Each longeron of a plurality of longerons is disposed on the inflatable tube surface and spaced apart from each other and held in place by the inflatable tube, and in the hybrid inflatable boom inflated state the each longeron is extended in a direction of the inflatable tube longitudinal boom direction. A method for deploying a deformable hybrid inflatable boom is also described.

Abstract: A trussed collapsible tubular mast includes a deformable beam having an extended state, a flattened state, and a rolled state, where a stiffness and strength of the deformable beam in the extended state is greater than a different stiffness and a different strength of the deformable beam in the flattened state. At least one collapsible tubular mast wall has a plurality of truss members of a first material having a first material thickness. At least one truss member is disposed substantially perpendicular to a longitudinal axis of the trussed collapsible tubular mast. Disposed between the truss members is a wall area of a second material thickness less thick than the first material thickness.

Abstract: A deformable device includes a deformable beam or hinge having an extended state, a flattened state, and a rolled state if a beam, where a stiffness and strength in the extended state is greater than a different stiffness and strength in the flattened state, the deformable beam or the hinge deformable along a long axis. An end face cross section transverse to the long axis includes a first periodic curved member which defines at least two shaped curves. A second periodic curved member defines at least two shaped curves. The second periodic curved member is mechanically coupled to the first periodic curved member at respective ends of the end face cross section. The first arc length of the first periodic curved member and the second arc length of the second periodic curved member are of about a same arc length.

Abstract: A deformable device includes a deformable beam or hinge having an extended state, a flattened state, and a rolled state if a beam, where a stiffness and strength of the deformable beam or the hinge in the extended state is greater than a different stiffness and strength of the deformable beam or the hinge in the flattened state. A cross section includes a first about V shape half and a second about V shape half. Each half includes a vertex with at least one curve extending into two walls at least one of the walls including a plurality of truss members, both of the walls extend into a joining edge. The first about V shape half and the second about V shape half are joined together at a seam of a joining edge of the first about V shape half and the second about V shape half.

Abstract: A deformable device has an extended state, a flattened state, and a rolled state if a beam, where a stiffness and strength of the deformable beam or hinge in the extended state is greater than a different stiffness and strength of the deformable beam or hinge in the flattened state. An end face cross section includes a main C curved member which defines an about circular shape of an arc ranging between about a quarter arc and a substantially full circle. A periodic C curved member defines at least two about C shaped curves. The periodic C curved member has a first periodic C curved member end mechanically coupled to the first main C curved member end, and a second periodic C curved member end mechanically coupled to the second main C curved member end. A deformable device with a V shaped member is also described.
