Flowfield Simulation About a 65-Degree Delta Wing During Constant Roll-Rate Motions

摘要

THE effects of roll and yaw rates on aerodynamic reactions and vortex breakdown locations for a 65-deg delta wing are described. Two distinct maneuvers are numerically simu- lated to isolate the rate effects. The first is a constant-rate con- ing motion, with computed body-axis moments compared with rotary data from the U. S. Air Force Research Laboratory (AFRL) vertical wind tunnel. The second is a constant-roll rate, barrel-roll maneuver with zero itch and yaw rates. In both maneuvers, the angle of attack and sideslip angle are fixed at 30 and 0 deg, respectively.
