66 -- INSTRUMENTATION TUBE SOL RFQ125932 DUE 052899 POC Alice J. Wilson, Contract Specialist, Phone (216) 433-2552, Fax (216) 433-5489, Email Alice.J.Wilson@grc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/GRC/date.html#RFQ125932. E-MAIL: Alice J. Wilson, Alice.J.Wilson@grc.nasa.gov. NASA/GRC plans to issue a Request for Quotation (RFQ) for UHB Drive Rig Instrumentation Tube: Instrumentation tube and 150-channel slipring. The wiring tube assembly is required to spin up to 20,000 RPM without adding any imbalance to the turbine drive rig assembly, or adding any strain to the soldered wire connections on both ends of the the tube. On the forward end of the assembly the wiring harness is terminated to a 104 pin female mating connector, which is potted into the tube. This provides the interface with the dynamic balance through an existing dynamic transition connector assembly. On the aft end of the the tube assembly the wiring harness is transitioned through a quill shaft to the slipring interface connector. In addition to the 104 channels, which originate from the front connector, there is an additional 40 channels added in the turbine assembly section to accommodate strain gages from he turbine rotor blades. SPECIFICATIONS: INSTRUMENTATION TUBE: Material=AMS 5560 (304 stainless), Length= 103.82",O.D.=1.00",I.D.=0.965" WIRE HARENESS: Wire type=7/38 SPC wrapped Kapton wire, Wire gage=30 AWG FORWARD DYNAMIC SIGNAL TRANSITION CONNECTOR: Material=Nylon 66, Chan=104 This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/GRC intends to purchase the items from International Instrumentation, Inc. P.O. Box 153, Bunn, NC 27508. International Instrumentation Inc, formerly called Quality Aero Technology (QAT) originally designed and built the instrumentation assembly, which includes the the instrumentation tube and the 150-channel slipring. The instumentation tube is a replacement part for an exisiting turbine drive rig assembly. This turbine drive rig is used in the 9x15 Low Speed Wind Tunnel to power various fan models to speeds up to 17,000 RPM and 5,000 SHP. The instumentation tube assembly is designed to transition signals from the dynamic (spinning) part of a model to a 150-channel slipring at the aft end of the drive rig so that the rotating information can be processed. THE AUTHORITY FOR OTHER THAN FULL AND OPEN COMPETITION is 10 U.S.C. 2304(c)(1). The Government intends to acquire a commercial item using FAR Part 12. Interested firms have 10 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 10 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Oral communications are acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. OMBUDSMAN STATEMENT REQUIRED] An Ombudsman has been appointed. See Internet Note "B". Posted 05/18/99 (D-SN332836). (0138)
