A -- STIRLING ENGINE/ALTERNATOR ASSEMBLY SOL 98-8 POC Ms. Robin Bennett, 814-865-4216 Research and Development -- Potential Sources Sought Applied Research Laboratory of The Pennsylvania State University (ARL Penn State), North Atherton Street, P. O. Box 30, State College, PA 16804 STIRLING ENGINE/ALTERNATOR ASSEMBLY Sol 98-8, POC, Robin Bennett, Contracts and Subcontracts Specialist, voice (814)865-4216 or email krb105@psu.edu. Sources are sought to perform a preliminary design study of a Stirling engine/alternator assembly, and to use this design as the basis for estimating the performance of a developed unit and the cost and development schedule associated with the possible subsequent detailed design, fabrication, and development testing of three units of this device, which may or may not be acquired, at ARL Penn State's option, via a subsequently negotiated development subcontract. The envisioned preliminary design study shall be performed under a firm, fixed price subcontract of approximately three months duration. Multiple preliminary design studies may be awarded, dependent upon the quality of offers received and the availability of funding, and the results used by ARL Penn State as a basis to award a subsequent sole source or competitively bid development subcontract to obtain three Stirling engine/alternator assemblies. The Stirling engine/alternator assembly sought must fit within an 18.5" diameter cylinder and will exchange heat with a chemical heat source operating at up to 1700 F and a cold side heat exchanger operating at about 60 F. The hot side heat source will be of a type currently under development at ARL Penn State and the specifications of the heat source/engine hot side will be jointly developed by ARL Penn State and the selected subcontractor(s) during the preliminary design. The desired alternator output power is a nominal 3 kW at the design point with the capability to adjust the output both above and below this power level, as required, within a practical range. It is anticipated that the alternator output voltage will be about 375 V at the 3 kW design point, orat alternative voltages identified as more advantageous during parametric performance tradeoff analyses conducted during the preliminary design effort. Maximum efficiency from a minimum weight and volume package are sought during the preliminary design effort. Free-piston, kinematic, or alternate engine configurations may be considered at the offerer's discretion. This announcement is made to determine interest only and does not commit ARL Penn State to make any award or to pay any response preparation costs. Interested potential sources are advised that the hot side heat source concept is proprietary to ARL Penn State and other third parties and potential sources shall have no rights thereto, except for the sole, limited purpose of preparing a proposal pursuant to a request for proposal for a Stirling engine/alternator when issued. The formal RFP will be issued on or about 13 April 1998. Potential sources are requested to send a letter of interest and capability along with hardware brochures and other descriptive non-proprietary literature to Ms. Robin Bennett, Contracts and Subcontracts Specialist, The Pennsylvania State University, North Atherton Street, P.O. Box 30, State College, PA 16804, not later than 10 days after the publication date of this CBD announcement. (0089)
