A -- MICRODYNAMIC STRAIN SENSOR TESTING SOL N00014-95-R-SK01 POC Susan Kelly, Contract Specialist, Code 3230.SK, (202) 767-0666. Helen Paul, Contracting Officer, Code 3230.HB, (202) 767-0666. THE NAVAL RESEARCH LABORATORY INTENDS To NEGOTIATE ON AN OTHER THAN FULL AND OPEN COMPETITIVE BASIS With HUGHES DANBURY OPTICAL SYSTEMS FOR THE TESTING AND VALIDATION Of ULTRAHIGH SENSITIVITY OPTICAL FIBER STRAIN SENSORS ATTACHED To PROTOTYPE SPACECRAFT STRUTS. THE STRAIN MEASUREMENTS SHALL Be MADE ON AN INSTRUMENT WITH THE DEMONSTRATED CAPABILITY Of SIMULATING EITHER SPACE (0g) OR GROUND (1g) AXIAL LOADING On THE STRUTS AND MEASURING THE DAMPING FOLLOWING MECANICAL EXCITATION USING CONVENTIONAL SENSORS With STRAIN SENSITIVITIES OF ( 1 PARTS-PER-BILLION (ppb). THESE RESULTS SHALL BE COMPARED WITH STRAIN MEASUREMENTS TO THE ppb LEVEL USING GOVERNMENT-FUNISHED FIBER OPTIC STRAIN SENSORS MOUNTED On THE SRUTS AND The ASSOCIATED GOVERNMENT-FUNISHED OPTOELECTRIC INSTUMENTATION. FOUR DIFFERENT STRUT CONFIGURATIONS SHALL Be TESTED, INCLUDING GOVERNMENT FURNISHED FUSED QUARTZ ROD, Low THERMAL EXPANSION COEFFICIENT P-100S CYANIDE ESTER COMPOSITE STRUT, Low THERMAL EXPANSION COEFFICIENT P-100S CYANIDE ESTER COMPOSITE STRUT With JOINT AND A BORON-FILLED GRAPHITE COMPOSITE STRUT SUPPLIED By THE CONTRACTOR. BASELINE MEASUREMENTS UNDER BOTH SPACE And GROUND SIMULATED CONDITIONS MUST BE PERFORMED PRIOR To FO SENSOR ATTACHMENT TO DETERMINE If THE SENSORS AFFECT THE MICRODYNAMIC PROPERTIES OF THE STRUTS. REQUIRED DELIVERY DATES For DATA AND ANALYSIS OF DAMPING AS A FUNCTION OF STRAIN AS MEASURED By CAPACITANCE GAGES AND COMPARISON WITH STRAIN MEASUREMENTS By FO SENSORS ON EACH OF THE TEST ARTICLES Are 30 DEC 95, 30 JUN 96, 31 AUG 96 AND 31 MAR 96, RESPECTIVELY. Any RESPONSES TO THIS NOTICE OF INTENT TO NEGOTIATE WITH HUGHES DANBURY OPTICAL SYSTEMS SHOULD Be SUBMITTED IN ACCORDANCE With Note 22. SYNOPSIS SKO1. (0135)
