Abstract
A DESIGN FOR A RUGGED, HIGH-FREQUENCY, ACCELERATION-INSENSITIVE AIRBLAST GAGE IS PROPOSED. THE PROPOSED GAGE SHOULD HAVE ITS FUNDAMENTAL VIBRATION FREQUENCY ABOVE 400 KHZ, BE ROUGHLY CYLINDRICAL IN SHAPE WITH DIAMETER AND LENGTH BOTH LESS THAN ONE INCH, AND HAVE BUILT-IN COMPENSATION WHICH WILL LIMIT SPURIOUS SIGNALS DUE TOACCELERATION TO VERY LOW LEVELS. FULLSCALE OUTPUT FOR AN APPLIED AIRBLAST PRESSURE OF 80,000 PSI SHOULD BE ABOUT 30 MV WITH AMPLIFIER GAIN OF ONE, AND 300 MV WITH A LOW AMPLIFIER GAIN OF 10. SIGNAL CONDITIONERS WILL NOT BE A PART OF THE GAGE, BUT CAN BE REMOVED THOUSANDS OF FEET WITH NO IMPAIRMENT OF GAGE RESPONSES. THE PROPOSAL SHOWS THE DESIGN CONCEPT, GIVES RESULTS OF DESIGN CALCULATIONS TO PREDICT GAGE RESPONSE, AND PRESENTS A PROGRAM FOR FINAL DESIGN, CONSTRUCTION OF PROTOTYPE GAGES, AND BLAST AND ACCELERATION TESTING OF THE PROTOTYPE GAGES.
