NASA 1996 SBIR Phase I


PROPOSAL NUMBER : 96-1 07.07-4000

PROJECT TITLE : Development of a Fully Integrated Composite Flywheel

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

Foster Miller will design and fabricate a braided composite hub which will enable production of an integral hub/rim flywheel for spacecraft applications. High performance composite flywheels are under development to replace both the batteries and the conventional attitude control wheels with an Integrated Power and Attitude Control System (IPACS). The innovative one piece flywheel will be fabricated using a proven, proprietary Foster-Miller process for direct integration of separately preformed composite parts for greatly improved performance in high speed rotating machinery. Working closely with our no cost team member, SatCon Technologies, who is currently developing flywheel-based IPACS for commercial satellites, Foster-Miller will demonstrate the feasibility of manufacturing a fully integrated composite flywheel. Following successful completion of the Phase I program, SatCon will pursue further development both in a Phase II program as well as through other funding channels. The proposed program directly supports the topic requirement of lightweight flywheel energy storage systems with high energy and power density. Using the Foster Miller integrated composite flywheel design, the SatCon IPACS will be able to meet the energy storage and control requirements of future spacecraft.
POTENTIAL COMMERCIAL APPLICATIONS
Flywheel energy storage systems, fabricated primarily from composite materials, are being developed for many transportation modes including transit buses, trains, cars, uninterruptable power sources (UPS), space stations and satellites. Consequently, the innovative Foster Miller integral flywheel design has significant potential for commercial business development in a range of industries.
