Description/Abstract:
THE PURPOSE OF PROJECT 3.30 OF OPERATION UPSHOT-KNOTHOLE WAS TO DEVELO P AND PROOF-TEST SELF-RECORDING GAGES FOR THE MEASUREMENT OF PRESSURE- TIME AND PEAK PRESSURE IN CONNECTION WITH AIR BLAST WAVES FROM NUCLEAR EXPLOSIONS. TO ACCOMPLISH THIS PURPOSE, PROTOTYPES WERE MANUFACTURED FOR THREE TYPES OF GAGES IN QUANTITIES OF 10 TO 30. THEY WERE EMPLOYED IN NUMEROUS WAYS ON SEVERAL SHOTS TO DETERMINE THEIR CHARACTERISTICS, LIMITATIONS AND CAPABILITIES. A NYLON AND CARBON PAPER INITIATION DEV ICE WAS USED ON THE PRESSURE-TIME GAGES TO START THE RECORDING DISC AT A FINITE TIME AFTER THE DETONATION OF THE DEVICE. THE PRESSURE-TIME G AGES WERE ACCURATE TO PLUS OR MINUS PERCENT AND RECORDED WAVE SHAPES V ERY SIMILAR TO THOSE OBTAINED BY MORE EXPENSIVE ELECTRONIC INSTRUMENTA TION. THE PEAK PRESSURE GAGES WERE ACCURATE TO PLUS OR MINUS PERCENT A ND NO INITIATION DEVICES WAS NEEDED. THE COMPONENTS OF THE GAGES TESTE D FORM A BASIS FOR OTHER GAGES TO MEASURE FLOW PHENOMENA, UNDERWATER P RESSURES, GROUND SHOCK, ACCELERATION AND TEMPERATURE PHENOMENA, IT IS RECOMMENDED THAT THE DEVELOPMENT OF A SERIES OF SELF-RECORDING GAGES F OR THE MEASUREMENT OF VARIOUS PHENOMENA ASSOCIATED WITH THE DETONATION OF ATOMIC DEVICES BE VIGOROUSLY PURSUED. IT IS CONCLUDED THAT GAGES O F THE TYPE TESTED CAN GIVE USEFUL DATA, ON TESTS REQUIRING GREATER COV ERAGE AND LONGER BLAST LINES, WITH SUFFICIENT ACCURACY AND FOR LESS EX PENDITURE IN MONEY, MAN-POWER, AND TIME, THAN IS POSSIBLE WITH OTHER T YPES OF INSTRUMENTATION.
