E-MAIL: rick.stewart@arnold.af.mil, rick.stewart@arnold.af.mil. Background "The Arnold Engineering Development Center's (AEDC) Aero- Propulsion Test Facility (ASTF) is a turbine engine test facility built in the late 1970's. The existing axial compressor drives consist of twelve 27,500 horsepower synchronous motors, four 44,000 horsepower synchronous motors, and two 52,500 horsepower synchronous motors. The starting system for these motors is one of two variable frequency starting systems (VFSS) which are located at each end of the facility and linked together for redundancy. This project will replace the two Variable Frequency Starting Systems with new Variable Frequency Drive Systems at the Engine Test Facility (ETF) C-Plant at Arnold Engineering Development Center. This turn key job consists of replacing selected components of the systems with new components. Those items to be replaced with new components include, but are not limited to, the inverter, rectifier, dc link and controls cubicle. This work also includes demolition of selected components of the existing systems and installation and integration of the new equipment. Because of funding and mission requirements, the project must be accomplished in at least 3 or 4 phases. AEDC is soliciting comments and suggestions for the best means of economically accomplishing our objectives. Areas of particular interest are technical tradeoffs, trends in technology, phasing the work, risks, and appropriate discriminators to use to determine best value. Electronic transmission of any information is preferred but it will be accepted in any format. This is not a request for proposals. A formal solicitation package will be developed within the next 3-6 months that will consider any information received from this request for information " Posted 04/17/00 (D-SN445665). (0108)
