Multifunctional Tanks for Spacecraft
- Wednesday, 15 November 2006
A document discusses multifunctional tanks as means to integrate additional structural and functional efficiencies into designs of spacecraft. Whereas spacecraft tanks are traditionally designed primarily to store fluids and only secondarily to provide other benefits, multifunctional tanks are designed to simultaneously provide multiple primary benefits. In addition to one or more chamber(s) for storage of fluids, a multifunctional tank could provide any or all of the following:
- Passageways for transferring the fluids;
- Part or all of the primary structure of a spacecraft;
- All or part of an enclosure;
- Mechanical interfaces to components, subsystems, and/or systems;
- Paths and surfaces for transferring heat;
- Shielding against space radiation;
- Shielding against electromagnetic interference;
- Electrically conductive paths and surfaces; and
- Shades and baffles to protect against sunlight and/or other undesired light.
Many different multifunctional-tank designs are conceivable. The design of a particular tank can be tailored to the requirements for the spacecraft in which the tank is to be installed. For example, the walls of the tank can be flat or curved or have more complicated shapes, and the tank can include an internal structure for strengthening the tank and/or other uses.
