- Description
- This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). Background: Mission: NASA is developing a plan to build a Re-useable Launch Vehicle (RLV) to replace the space shuttle within the next 10 years. The goals are to make the RLV 10 times cheaper to build and operate and 100 times safer than the existing shuttle. All of the new vehicle's subsystems are being studied to determine safer and more economic designs. Primary Electric Power System: Electric circuit transient power estimates for the next generation RLV range from 40 to over 200 horsepower. Space-flight rated power systems that withstand such transients do not exist. Distribution voltages are expected to be from 300 to 600 volts. These high voltages will cause disruptive discharge during ascent and descent maneuvers unless special packaging concepts are developed. Power Distribution Unit (PDU): The Glenn Research Center proposes to design, build, and test a power distribution unit that will control the power delivered to large transient electrical loads. The PDU will house current-limiting power controllers that receive command and control signals from a remote source over a digital communication network. Each power controller will be rated for 25 amperes capacity. Power controllers can be connected in parallel to increase the current-limiting capacity. An external connector module will control the parallel configuration. The PDU itself will be modular using an input module for the supply bus; a power controller cage to house five power controller modules; and a distribution module to configure the outputs of the power controllers. These three PDU modules will control 100 amperes current at the system distribution voltage. Additional groups of these three modules can be added to further increase the current distribution capacity. Contractor Services Required: The contractor shall work with the NASA Glenn design team to design high-voltage distribution systems for re-useable launch vehicles. The systems shall consist of Power Distribution Units (PDU's) and the external wiring that connects these units together. All components shall be designed to operate together in a re-useable launch vehicle environment assumed to be the same as existing shuttle's. Systems shall be specified for use at 270 volts per MIL STD 704E. Services shall be for: 1. PDU Packaging - The contractor shall specify all of the design features that preclude corona and disruptive discharge within the mechanical modules that constitute the PDU. Nominal working voltages shall be 270volts DC per MIL-STD-704E. Consultant shall build proof-of-concept circuits that will be used in the final PDU prototype and test them. ? Circuits shall be current limiting type capable of being paralleled to increase current limit capacity. Individual current limiting circuits shall limit at 30 amps. ? Circuits shall use redundant series-connected voltage reducing stages to accommodate short-circuited stages. ? Consultant shall specify and implement I/O protocols for operating the circuits. Deliverables: Five proof-of-concept circuit boards. The contractor shall summarize the work performed in a written report. The report topics shall include as a minimum: ? Summary of the recommended designs and components including rationales for the recommendations. ? Calculations and supporting analyses. ? Test results Schedule: The period of performance for this effort shall not exceed 5 months from award of the order. The provisions and clauses in the RFQ are those in effect through FAC 01-06. This procurement is a total small business set-aside. See Note 1. The NAICS Code and the small business size standard for this procurement are 335999 and 500, respectively. The quoter shall state in their quotation their size status for this procurement. All qualified responsible business sources may submit a quotation which shall be considered by the agency. Delivery to Glenn Research Center is required within 90 days ARO. Delivery shall be FOB Destination. The DPAS rating for this procurement is DO-C9. Quotations for the items(s) described above are due by May 10, 2002 at 4:30 local time and may be mailed or faxed to NASA Glenn Research Center Attn: Timothy M. Bober 21000 Brookpark Road Mail Stop: 500-306 Cleveland, Ohio 44135. Fax Number (216) 433-2480 and include, solicitation number, FOB destination to this Center, proposed delivery schedule, discount/payment terms, warranty duration (if applicable), taxpayer identification number (TIN), identification of any special commercial terms, and be signed by an authorized company representative. Quoters shall provide the information required by FAR 52.212-1. If the end product(s) quoted is other than domestic end product(s) as defined in the clause entitled "Buy American Act -- Supplies," the quoter shall so state and shall list the country of origin. The Representations and Certifications required by FAR 52.2l2-3 may be obtained via the internet at URL: http://ec.msfc.nasa.gov/msfc/pub/reps_certs/sats/ FAR 52.212-5 is applicable and the following identified clauses are incorporated by reference: 52.222-26, Equal Opportunity (E.O. 11246) 52.222-35, Affirmative Action for Disabled Veterans and Veterans of the Vietnam Era (38 U.S.C. 4212) The FAR may be obtained via the Internet at URL: http://www.arnet.gov/far/ The NFS may be obtained via the Internet at URL: http://www.hq.nasa.gov/office/procurement/regs/nfstoc.htm Questions regarding this acquisition must be submitted in writing no later than May 2, 2002. Award will be based upon overall best value to the Government, with consideration given to the factors of proposed technical merits, price and past performance; other critical requirements (i.e., delivery) if so stated in the RFQ will also be considered. Unless otherwise stated in the solicitation, for selection purposes, technical, price and past performance are essentially equal in importance. It is critical that offerors provide adequate detail to allow evaluation of their offer (see FAR 52.212-1(b). Quoters must provide copies of the provision at 52.212-3, Offeror Representation and Certifications - Commercial Items with their quote. See above for where to obtain copies of the form via the Internet. An ombudsman has been appointed - See NASA Specific Note "B". It is the quoter's responsibility to monitor the following Internet site for the release of amendments (if any): http://prod.nais.nasa.gov/cgi-bin/eps/bizops.cgi?gr=C&pin=22 Potential quoters will be responsible for downloading their own copy of this combination synopsis/solicitation and amendments (if any).
