SATPC0041878 Tab 04 4 SOW..pdf

The requester seeks precision manufacturing and instrumentation of a test section for the GRC Distorted

Duct Flow Rig. The deliverables must include:

1) The “bump” test section shown in attached sketch SK40004_RevA.pdf, conforming to all specified tolerances,

2) Three direct-measurement shear stress sensors of 0.149” diameter installed on the bump (top of test section in section view A-A on sheet 2 of SK4004) whose faces conform to the curvature of the test section inner mold line,

3) Three direct-measurement shear stress sensors of 0.149” diameter containing flange at 0.250” offset from the measurement surface to facilitate easy removal from the test section,

4) Three contoured flanged blanks which may serve to replace the flanged shear stress sensors in the delivered test section, and

5) All necessary external electronics, cabling, and connectors to facilitate shear stress measurement with a voltage measurement device.

The completed order should be delivered to:

NASA Glenn Research Center

21000 Brookpark Rd, Cleveland, OH 44135

Delivery is expected <18 weeks ARO.
