Public award description

THE PURPOSE OF THIS CONTRACT IS (A) TO VERIFY SENSITIVITIES OF SPECIFIC CAMERA CONFIGURATIONS EMPLOYED DURING INSPECTION TO STANDARD THROUGH-TRANSMISSION MEASUREMENTS; (B) TO DEVELOP REFERENCES FOR VERIFICATION OF SYSTEM UNIFORMITY AND OF PROPER OPERATION SETUPS; (C) TO DETERMINE INDEPENDENT VARIABLES OF A REGRESSION WITH BREAKAGE STRENGTH AS THE INDEPENDENT VARIABLE. THE CONTRACTOR SHALL COMPARE THE STRESS PHOTONICS CAMERA SENSITIVITIES (CAMERAS AT KSC AND THE RESEARCH UNIT AT LARC) TO STRESS FIELDS AROUND DAMAGE SITES IN SHUTTLE WINDOW GLASS. THE CONTRACTOR SHALL WRITE A REPORT OF RESULTS AND DELIVER DATA FILES TO NASA CONTRACT MONITOR. THE CONTRACTOR SHALL DESIGN, FABRICATE, AND TEST THREE SETS OF CALIBRATION STANDARDS (PHANTOMS OF THE DAMAGE SITE MEASUREMENTS) FOR USE WITH THOSE STRESS PHOTONICS CAMERAS PROCURED BY OR FOR NASA. TO TEST CALIBRATION STANDARDS, THE CONTRACTOR SHALL USE ALL STRESS PHOTONICS CAMERAS AT KSC, DESIGNED FOR SHUTTLE WINDOW INSPECTION, AND THE THROUGH-TRANSMISSION CAMERA USED AT LANGLEY RESEARCH CENTER (LARC). THE CONTRACTOR SHALL CORRELATE STRESS FIELD DATA COLLECTED FROM DAMAGE SITE SPECIMENS BEFORE FRACTURE (BREAKING) LOADS WERE APPLIED.
