摘要:
An aircraft including a space frame fuselage structure. A plurality of panels are connected with the structure and configured to form a skin over the structure. The panels are movable relative to one another so as to prevent loading of the structure from inducing loading in the skin.
摘要:
A solar concentrator including a housing having a receiving wall, a reflecting wall and at least two end walls, the receiving, reflecting and end walls defining a three-dimensional volume having an inlet, wherein a vertical axis of the housing is generally perpendicular to the inlet, a receiver mounted on the receiving wall of the housing, the receiver including at least one photovoltaic cell, wherein a vertical axis of the receiver is disposed at a non-zero angle relative to the vertical axis of the housing, at least one clip disposed on the reflecting wall, an optical element received within the three-dimensional volume, the optical element including at least one tab, the tab being engaged by the clip to align the optical element with the receiver, and a window received over the inlet to enclose the housing.

摘要:
A method and apparatus for controlling the shape of a control surface. A structure is rotated about an axis. The structure is located between a flexible skin and a skin located substantially opposite of the flexible skin. An assembly is moved to change the shape of the control surface in response to a rotation of the structure. The assembly is movably connected to the structure and is configured to move such that the flexible skin forms a plurality of curvatures.
摘要:
An aircraft for carrying cargo in one or more containers. The aircraft includes a fuselage structure having a plurality of nodes and a plurality of elements connecting the nodes to form a space frame in which to carry cargo. At least some of the nodes are positioned in the space frame based on dimensions of the one or more containers. The fuselage structure is more compact, lighter and less expensive compared to conventional semi-monocoque fuselages.

摘要:
A sandwich structure includes a first skin, a second skin, a first hinge member, and a second hinge member. The first hinge member may be movably coupled to the first skin and a first skin joint. The second hinge member may be movably coupled to the second skin and second skin joint. The first hinge member and the second member may be movably coupled to one another and a member joint located between the first and second skin joint.

摘要:
In one embodiment, a solar collector comprises a solar cell attached with a heat exchanger, and a restraining member attached to the heat exchanger. The restraining member at least partly restrains the heat exchanger when heated. In further embodiments, restraining members and methods are disclosed for at least partly restraining the thermal expansion of a solar collector.
摘要:
A solar energy system including a pedestal defining a longitudinal axis, a frame that is supported by the pedestal and that is rotateable relative to the pedestal about the longitudinal axis, the frame including at least one solar device, and a wind vane operatively connected to the frame to urge the frame relative to the pedestal about the longitudinal axis in response to wind acting on the wind vane.
