Abstract:

A NEW LOW-SPEED AERODYNAMIC DATABASE FOR THE F-16VISTA WAS DEVELOPED FROM LOW-SPEED DATA SETS OBTAINED FROM NASA LANGLEYS 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.
