A -- FLYWHEEL ROTOR HEALTH MONITORING RESEARCH & DEVELOPMENT SOL RFO3-8499 DUE 110199 POC Timothy C. Pierce, Contract Specialist, Phone (216) 433-2147, Fax (216) 433-5185, Email Timothy.C.Pierce@grc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/GRC/date.html#RFO3-8499. E-MAIL: Timothy C. Pierce, Timothy.C.Pierce@grc.nasa.gov. NASA/GRC intends to purchase a Flywheel Rotor Health Monitoring Research and Development effort from the University of Texas at Austin's Center for Electomechanics (UT-CEM). Justification to permit contracting with UT-CEM has been prepared using 10 U.S.C. 2304(c)(1) as its authority. The procurement will build upon a proprietary UT-CEM flywheel rotor design approach to develop a rotor health monitoring system that will enhance the safety, reliability, and performance of flywheel systems in general, and the flywheel system being developed for the ISS in particular (note that the ISS flywheel system employs a UT-CEM rotor). UT-CEM has a developed a unique rotor design that includes specific design features that provide an enhanced signature indicating that a failure is incipient. This goals of this procurement are to (1) develop an operational rotor health monitoring system for the UT-CEM rotor using dedicated sensors to detect the signature of an impending failure, (2) provide test units that can used to validate analytical models of the impact on flywheel system performance, and (3) to demonstrate the health monitoring system in an operational flywheel system. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. See Note 22. An Ombudsman has been appointed. See Internet Note "B".
