- Description
- THIS IS A SOURCES SOUGHT NOTICE ONLY. This sources sought does not constitute an invitation for Bids, Request for Proposals, nor Request for Quotations and is not to be construed as a commitment by the government to issue a contract or otherwise pay for the information requested. Background: The majority of the heat transfer measurements made in the AEDC Hypervelocity Wind Tunnel 9 facility have been collected using coaxial thermocouples mounted directly into a stainless steel substrate (15-5PH or 17-4PH stainless steel) test article. Typical wall thickness of the steel substrate generally ranges between 0.5"-0.25" and interior volume to route lead wires can be limited. These installation limitations require the sensor length to be similar to the wall thickness and the transition from the sensor shell to the lead wires must occur close to the base of the sensor. Finally, a thin layer of temperature sensitive paint is often applied directly on the wind tunnel model after the coaxial thermocouples have been installed and contoured to the test article. Type-E, Chromel-Constantan, coaxial thermocouples have been successfully utilized for over 30 years in the unique and stressing Tunnel 9 hypervelocity test environment due to their high durability, fast-response times and their ability to be contoured to the outer mold lines of the test article. Surface temperature response is acquired during the test run using a coaxial thermocouple and the heat transfer is derived using the coaxial thermocouple temperature data as boundary condition to a finite-differencing solution of the transient heat conduction equation for a finite thickness wall. Sensor installation and data utilization techniques have been optimized at Tunnel 9 to provide highly accurate temperature/heat transfer measurements in Tunnel 9. A significant amount of resources have been used to characterize their performance over the years with extensive testing and analytical modeling. As a facility, Tunnel 9 is always looking to improve the state-of-the-art in measurement technology; however, the validation for opportunities to evaluate different coaxial gages for making heat transfer measurements of a new technique is costly and time-consuming. As such, we continue to search the marketplace for potential alternate suppliers of coaxial thermocouples so that these new sensors can be experimentally evaluated in the Tunnel 9 environment before a large scale procurement and deployment into future test programs. The purpose of this sources sought synopsis is to identify businesses having the capability to provide miniature, fast-response coaxial thermocouples for use in the Tunnel 9 Hypervelocity Wind Tunnel with the following salient characteristics/features: 1. NIST-traceable Type-E, Chromel-Constantan thermocouple materials (outer sheath Chromel and inner pin Constantan) 2. Outer sensor cylinder diameters of 0.061" or smaller 3. Sensor to be installed into test article using adhesives such as Loctite #271 or #620 4. Sensor can be contoured to outer-mold-lines of test article after adhesive fully cured 5. Thermocouple junction at the outer surface of the model created by abrasion (file and/or sand paper). 6. Fast response time to metal wall surface temperature changes, typically on the order of microseconds 7. Transition from coaxial thermocouple body to lead wires to occur close to body, approximately 0.15 or less" 8. Any strain relief applied between the coaxial thermocouple body and lead wires cannot be larger than the cylindrical diameter of the coaxial thermocouple body 9. Lead wires from coaxial thermocouple assembly to be provided as either Type-E thermocouple wire or with copper wires welded to thermocouple wires approximately 4" from sensor base. Lead wires should be no larger than 30 AWG Teflon insulated solid wires. In response to this notice, please address the following: 1) Has your product been utilized in a hypersonic wind tunnel testing environment or other similar application as described above? If so, what applications, facilities and/or organizations have they been utilized? 2) Respond to each of the characteristics/features as standard or non-standard. 3) Respond with the method provided to meet the non-standard characteristics/features. 4) Is your company an authorized distributer or the actual manufacture? 5) Can you provide a specification sheet of the product solution for characteristic/feature comparison? 6) What would be the estimated time to deliver 30, 60 or 90 sensors? 7) Provide a statement about product warranty. 8) Does your company have a GSA contract available for this product? If so, provide your GSA contract number. 9) If this is solicited in the future, provide a price estimate (+-10%) and shipping costs FOB Arnold AFB, TN 37389? 10) Provide: a. Company Name b. Point of Contact (include address and telephone number) c. Duns & Bradstreet Unique Numbering System (DUNS) number if available d. Commercial and Government Entity (CAGE) code if available All responses are to be provided electronically no later than the date and time listed in this notification to the Contract Specialist, Miriam James, at email address: miriam.james@us.af.mil.
