E-MAIL: Stephanie D. Hunter, shunter@ems.jsc.nasa.gov. NASA/JSC plans to issue a Request for Offer (RFO) for the fabrication, acceptance testing, and delivery of 144 miniature cold gas thrusters for use on the RUSSIAN SAFER system developed at NASA/JSC. These thrusters will be used to build self rescue devices to be worn by astronauts during spacewalks, and must be manufactured, tested, and qualified to the highest standards consistent with manned space flight hardware. The thruster shall be manufactured per the following specifications and perform at the specified levels and conditions. The thrust shall be verified at ambient, such that the vacuum thrust at 230 psia is .08 lbf. The lsp shall be calculated to be 70 Lbf-sec/Lbm minimum. Minimum stall pressure with the coil at 180 deg F and 24 Vdc shall be 325 psig. Internal leakage shall not exceed 0.1 sccm at 230 psia inlet and 1 sccm at 65 psia inlet GN2 at 180 degF. Internal leakage shall not exceed 2 sccm at 230 psia inlet and 20 sccm at 65 psia inlet GN2 at -40 degF. External leakage shall be measured at ambient temperature only, and shall meet the same requirements. The valve shall operate on 24 volt nominal power supply. The coil resistance shall be 28 +/- 1.5 ohms at 70 deg F +/- 10 deg F. Insulation resistance shall be greater than 1 MOhm at 70 degF. The pull-in voltage shall be less than 19 Vdc with 265 psia inlet with coil at 180 degF. The drop out voltage shall be less than 2.5 Vdc with 230 psia inlet and the coil at -40 degF initial temperature. The opening response shall be less than 4.0 ms with 230 psia inlet with the coil at 180 deg F. The closing response shall be less than 4.0 ms with 230 psia inlet with the coil at -40 degF. The thruster shall be capable of completing a minimum of 20,000 cycles with a 230 psia inlet and 180 degF GN2. A qualification test shall be conducted to verify that the thruster meets specifications at completion of 20,000 cycles. The thruster shall be capable of completing a total on time of 570 seconds minimum at an inlet pressure at 230 psia in a vacuum. The thruster shall be capable of a continuous on time of 240 seconds, with flow at an inlet pressure of 230 psia. A qualification test shall be conducted to verify this specification. The minimum proof pressure shall be 600 psia. The minimum burst pressure shall be 1000 psia and shall be demonstrated by qualification test. The weight shall be less than .07 lb without the wire leads. The diameter shall be less than .6 inches. The total length along the thrust axis shall not exceed 1.0 inches including the nozzle, excluding the threaded and fitting. The wiring shall conform to MILW22759, 24-28AWG, prefer shielded per MILC27500. The fluid connection shall be 0.190-32UNF-3A per MILSTD7742. Soldering shall be per NHB5300.4. 24 units and the two qualification units shall be delivered by 3/31/1998. 24 more units shall be delivered 6/1/1998. These units shall be built to identical production drawings as used for the qualification units. Any changes must be approved by NASA. The four subsequent sets of 24 units will be delivered not later than as follows: 8/1/98, 9/1/98, 10/1/98, 11/1/98. The contractor shall establish and maintain a Quality Management System (QMS) on the contract date that complies with ANSI/ASQC Q9001-1994, American National Standard, Quality Systems Model for Quality Assurance in Design/Development, Production, Installation, and Servicing. Quotes should be provided as follows: an initial build of 50 units, with an option on 84 units, and as a single build of 134 units.. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. The DPAS Rating for this procurement is DO-C9. The provisions and clauses in the RFO and contract are those in effect through FAC 97-2. All qualified responsible sources may submit an offer which shall be considered by the agency. The anticipated release date of the RFO is on or about 1/12/98 with an anticipated offer due date of on or about 2/13/98. An ombudsman has been appointed -- See Internet Note "B". The solicitation and any documents related to this procurement will be available over the Internet. These documents will be in Microsoft Office Suite (Word 6.0, Excel 5.0, PowerPoint 4.0) format and will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.
