Abstract :
Q-Flex quartz flexure suspension technology has evolved to produce a world class accelerometer with thousands of units delivered in 1991. The Sundstrand Model QA3000 Q-Flex design achieves a new level of inertial grade performance while maintaining a competitive market price. The specification for the QA3000, supported by actual performance data, depicts performance characteristics superior in both bias and scale factor. Long term measurements display bias and scale factor repeatability obtained across temperature over a period of three years. These data exhibit improved thermal behavior with reduced errors. Reaction time and radiation data highlight the performance of the hybrid position detector circuit.<>
