Abstract : A NEW LOW-SPEED AERODYNAMIC DATABASE FOR THE F-16/VISTA WAS DEVELOPED FROM LOW-SPEED DATA SETS OBTAINED FROM NASA LANGLEY'S FACILITIES. THIS NEW MODEL WAS DESIGNED TO BE CONTINUOUS FROM -80 DEGREES TO +90 DEGREES ANGLE OF ATTACK, -30 DEGREES TO +30 DEGREES OF SIDESLIP, AND TO INCORPORATE ALL SIDESLIP AND CONTROL EFFECTIVENESS INTERACTIONS IN A FULLY NON-LINEAR STRUCTURE. THIS PAPER FIRST REVIEWS THE MODEL STRUCTURE AND DOCUMENTS THE AERODYNAMIC DATA SOURCE USED TO ASSEMBLE THE DATA. THE SUBSEQUENT DISCUSSION EXAMINES THE METHODOLOGY USED TO CORRELATE AND VALIDATE THE MODEL AGAINST FLIGHT TEST DATA AS WELL AS THE RATIONALES FOR THE MODEL CHANGES.
