Embedded Sensor Technology for Solid Rocket Motor Health Monitoring

摘要

Report developed under SBIR contract for topic A01-166 'Embedded Sensor Technology for Solid Rocket Motor Health Monitoring'. This report presents the progress achieved during this Phase I Option Program period. Results from constant load tests indicate that the current build standard of sensor is stable and shows little creep when under 75% full-scale tensile load for over a year. The sample broke at the bond line after 55 weeks and the sensor zero changed by only 3.8 psi with no change in the sensitivity. All required sensors have been manufactured and delivered with full specification and calibration sheets. The development of the Precision Semiconductor Strain Gage Matching System is reported and the expected improvement in performance confirmed.
