Abstract
The present disclosure relates to deployable structures and methods of use thereof. In particular, deployable structures with non-cylindrical or irregular shapes and methods of use thereof are disclosed. Non-cylindrical combustion elements can be used to rigidize such non-cylindrical or irregular shapes. The use of gaseous oxidizers along with deployable structures is also disclosed.
Claims20
A rapid deployment structure system comprising:
- a light-generating subsystem configured to generate light via a combustion reaction, the light-generating subsystem including:
- a combustion element,
- a source of gaseous oxidizer,
- a conduit containing the combustion element and fluidically coupled to the source of gaseous oxidizer, and
- a gas flow controller configured to control an amount of gaseous oxidizer supplied to the combustion element;
- a support element comprising a photo-curing structural composite material, wherein the support element has a collapsed configuration and an expanded configuration, the support element defines an enclosed volume having an inlet and an outlet, and the support element defines an axis in the expanded configuration;
- a scaffold disposed within the enclosed volume, wherein the scaffold supports at least a portion of the light-generating subsystem within the enclosed volume along at least a portion of the axis;
- an inflation system connected to the inlet of the enclosed volume and configured to supply fluid to the enclosed volume;
- and
- a pressure regulator connected to the outlet of the enclosed volume, wherein the pressure regulator is configured to vent products from a combustion reaction of the combustion element to a space outside the enclosed volume.
