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.

Overview
The document titled "Technical Support Package for Multifunctional Tanks for Spacecraft" (NPO-41407) is a NASA Tech Brief that outlines the development and application of Multifunctional Tanks (MFT) in spacecraft, particularly focusing on a prototype Low-Cost Adjunct Microspacecraft. The purpose of this technical package is to disseminate information about aerospace-related advancements that have potential technological, scientific, or commercial applications.
The MFT is designed to serve multiple functions within a spacecraft, which can include storage of propellant, structural support, and thermal management. This multifunctionality is crucial for reducing weight and complexity in spacecraft design, making it particularly beneficial for small and cost-effective space missions. The document includes diagrams and images that illustrate the design and components of the MFT, such as its controlled emissivity surface, multilayer circuit board, thermal gaskets, and tie-down assemblies.
One of the key features highlighted is the MFT's ability to integrate various systems into a single structure, which can lead to significant savings in both mass and volume. This integration is essential for microspacecraft, which often operate under stringent size and weight constraints. The document also emphasizes the importance of compliance with U.S. export regulations, indicating that the information may contain proprietary data.
Additionally, the document provides contact information for further assistance and resources available through NASA's Scientific and Technical Information (STI) Program Office. This includes access to a variety of publications and support services that can aid in understanding and utilizing the technologies discussed.
Overall, the Technical Support Package serves as a comprehensive overview of the MFT's design, functionality, and potential applications in space exploration. It reflects NASA's commitment to advancing aerospace technology and fostering innovation through the sharing of knowledge and resources. The insights provided in this document are valuable for researchers, engineers, and industry professionals interested in the future of spacecraft design and the role of multifunctional systems in enhancing mission capabilities.
