E-MAIL: Debbie R. Matthews, debbie.r.matthews@msfc.nasa.gov. In accordance with numbered Note 22, NASA/MSFC intends to negotiate on a sole source basis with WYLE LABORATORIES, 7800 Highway 20, West, Huntsville, Alabama for the non-cryogenic testing of a test damping seal. The stator surface roughness of the seal shall represent that of the Alternate Turbopump High Pressure Fuel Turbopump pattern with different seal clearances. Task requirements are as follows: Task 1: The contractor shall perform calibration of standard instrumentation. Standard instrumentation shall include transducers to measure pressure, flow and temperatures. In addition to the standard instrumentation, the contractor shall calibrate instrumentation relevant to the calculation of rotordynamic impedance functions. This instrumentation includes four(4) orthogonally-mounted internal Kaman proximity probes, four(4) orthogonally-mounted external proximity probes, and three(3) Kistler load cells. Task 2: The contractor shall perform the necessary facililty maintenance required to support the testing. This maintenance may include work on the steam turbine, filters, lines, valves, and rig assembly/teardowns as necessary. Task 3: The contractor shall perform testing on two government specified test bearings with the low preswirl shaft at seal pressure drops of 1500, 2000, and 2500 psi. The contractor shall also test the seal with shaft rotational speeds of 6000, 11000, and 16000 rpm at each pressure level. The external excitation force shall be a band-limited random force. The contractor shall digitize the test data in NASA format on tape. Task 4: The contractor shall perform testing on two government specfied test bearings with the high preswirl shaft at seal pressure drops of 1500, 2000, and 2500 psi. The contractor shall also test the seal with shaft rotational speeds of 2000, 4000, and 6000 rpm at each pressure level. The external excitation force shall be a band-limited random force. The contractor shall digitize the test data in NASA format on tape. Task 5: The contractor shall perform diagnostic testing as requested by NASA to ensure the quality of the desired data. Also, the contractor will conduct repeat ablility testing as requested by NASA to validate the test data. Task 6: Provide engineering drawings for two(2) test seals from conceptual drawings provided by the government. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). The Government intends to acquire a commercial item using FAR Part 12. Interested firms have until December 30, 1997, to submit in writing to the identified point of contact, their qualifications/capabilities.
