A Variable Geometry Plant Growth Unit

摘要: With long-term manned space missions now technologically feasible, life supports systems for the astronauts need to become self-sustaining and durable. Such a system would require plants to recycle waste and air. However, in the confined volume of a spacecraft, a unit to grow plants in the least amount of volume necessary would be necessary. This paper introduces a Variable Geometry Plant Growth Unit (VGPGU) developed at the University of Florida. The VGPGU developed, dubbed the" Accordion" for its resemblance to the musical instrument, is able to stretch and contract and efficiently deliver nutrients to the plants. Although the effects of microgravity cannot be simulated on earth, the design is expected to perform better in microgravity. With further testing and refinement, the Accordion can be adapted for a longterm space mission.
