Reconfigurable Polymeric Foam Structure

US Patent:
2010004, Feb 18, 2010
Filed:
Aug 14, 2008
Appl. No.:
12/191657
Inventors:
Mark S. Lake - Erie CO, US
Michael Hulse - Erie CO, US
Douglas Campbell - Longmont CO, US
Will Francis - Lyons CO, US
Steven C. Arzberger - Denver CO, US
Michael Terifay - Longmont CO, US
Assignee:
Composite Technology Development, Inc. - Lafayette CO
International Classification:
C08J 9/00
US Classification:
521 50
Abstract:
Methods, systems, and devices are described for fluid-dynamic structures operable to be reconfigured during use. Embodiments of the fluid-dynamic structures include a number of reconfigurable members separated by non-reconfigurable members. The reconfigurable members may be manufactured from temperature-sensitive polymeric foam, which become compliant at certain temperatures. The structure may also include an actuator assembly, operable to apply a reconfiguration force along a reconfiguration path, to reconfigure the structure between two or more volumetric shapes. Some embodiments also include a temperature regulation assembly for regulating the temperature of the reconfigurable members, and a structural attachment assembly for attaching the structure to a structure.

Damage And Leakage Barrier In All-Composite Pressure Vessels And Storage Tanks

US Patent:
8074826, Dec 13, 2011
Filed:
Jun 24, 2008
Appl. No.:
12/145255
Inventors:
John Cronin - Denver CO, US
Kaushik Mallick - Broomfield CO, US
Mark Lake - Erie CO, US
Mark Warner - Foothills Ranch CA, US
Naseem Munshi - Lafayette CO, US
Assignee:
Composite Technology Development, Inc. - Lafayette CO
International Classification:
F17C 1/00, F17C 1/02, F17C 1/06, B29C 53/58, B65H 81/00, B65D 1/40, B65D 8/04
US Classification:
220589, 220 6211, 220 6219, 220581, 220586, 220588, 220590, 156173, 156305, 206 06
Abstract:
A linerless tank structure has a body that defines an enclosed interior volume. The body has a cylindrical section having an axis of symmetry and a dome section coupled with the cylindrical section. The construction of the pressure vessel includes multiple fiber plies. At least one of the fiber plies is a helical ply having fibers traversing the dome helically about the axis of symmetry. At least a second of the fiber plies is a braided or woven ply.

Large-Scale Deployable Solar Array

US Patent:
8061660, Nov 22, 2011
Filed:
Sep 1, 2010
Appl. No.:
12/873615
Inventors:
Neal Beidleman - Aspen CO, US
Gregg Freebury - Lafayette CO, US
Will Francis - Boulder CO, US
Mark Lake - Erie CO, US
Rory Barrett - Erie CO, US
Philip N. Keller - Longmont CO, US
Robert Taylor - Superior CO, US
Assignee:
Composite Technology Development, Inc. - Lafayette CO
International Classification:
B64G 1/22
US Classification:
2441727, 2441733, 2441594, 2441595, 2441596, 2441726, 136245, 136292
Abstract:
A deployable structure is disclosed. The deployable structure may include one or more slit-tube longerons; and one or more flat sheets coupled with the one or more slit-tube longerons. The one or more slit-tube longerons and the one or more flat sheets may be stowed by rolling the one or more slit-tube longerons and the one or more flat sheets together into a roll. In one embodiment, at least a portion of the one or more slit-tube longerons may be exposed when stowed. In another embodiment, the one or more slit-tube longerons may be manufactured from a shape memory material. These slit-tube longerons unroll into to a straight configuration when exposed to heat.
