Modular Structures

Spirally folded hexagonal membrane structures with inflatable tubes and connective cable networks are presented aiming to establish possible construction scenarios of future large space structure systems over hundreds meters scale and corresponding structures based on the hierarchical modular structure concept using deployable membrane modules. Laboratory scale hand-made conceptual models are manufactured, and their deployment experiments are carried out to show their applicability to the hierarchical modular structures systems.

Abstract An effort is underway to develop a Proton Exchange Membrane (PEM) Fuel Cell system for future space applications. A breadboard system has been constructed and includes the following: reactant pressure regulators, ejector-based reactant pumps, a 4-kW fuel cell stack, and a passive, membrane-based oxygen / water separator. A computer model is being developed concurrently to analytically predict fluid flow in the oxidant reactant system. Preliminary data obtained from tests performed with the breadboard system, as well as other published data, has been used to validate the analytical component models. These components have been incorporated into an integrated oxidant fluid system model. Results obtained from both the performance tests and the analytical model are presented.
