TWO PRESENTATIONS WERE GIVEN AT THE NFMTC AND MODEL ATTITUDE MEETING ON JULY 29TH 2016 BY THE PRINCIPAL INVESTIGATOR ON DEVELOPING A RAPID ACCURATE AND EXIBLE DIRECT METHOD FOR THE CALIBRATION OF OW-THROUGH AND CONVENTIONAL SIX-COMPONENT FORCE BALANCES. IT IS PROPOSED THAT WORK CONTINUE TO DEVELOP THE MATLAB-BASED COMPUTER CODE. THIS CODE DIRECTLY UTILIZES THE AIAA FULL TERM POLYNOMIAL AUGMENTED WITH GAUSSIAN RADIAL BASIS FUNCTIONS (GRBFS). THE EXISTING CODE HAS BEEN TESTED ON PUBLISHED CALIBRATION EXAMPLES OF TWO-COMPONENT FOUR-COMPONENT AND SIX-COMPONENT FORCE BALANCES. IN ADDITION THE APPROACH HAS BEEN APPLIED TO THE VALIDATION OF HAND LOAD AND MACHINE LOAD DATA FROM THE CALIBRATION OF THE SIX-COMPONENT FORCE BALANCE OF REFERENCE [2]. THE PRELIMINARY RESULTS COMPARED WELL WITH THOSE OF BALFIT AND CONSISTENTLY GAVE HIGHER ACCURACY.
