AbstractVortex dynamics of more than 50 military wing configurations, such as diamond and delta wings with sweep back angles from 55º to 75º, were investigated in two wind tunnels and a water tunnel with over 10,000 runs at different test conditions. Investigations include flow visualizations (surface and off-surface flow field and vortex behavior), surface pressures (steady and unsteady pressure), air loads (stead and unsteady loads) and motion histories (harmonic, ramp –and-hold, free-to-roll and “forced” free-to-roll) as well as geometry and Re number effects. The motions include pitch, roll and coning motions. The ranges of angle of attack, roll and angle and coning angle are 0º~90º, ±180º and ±360º respectively with non-dimensional frequency 0.2 in pitch and roll and 0.6 in coning. The maximum Re and Mach number in wind tunnel is 3x10⁶ and 0.4 respectively. The comprehensive data setes have been edited into eight volumes of IAR reports. Only a brief of the program is presented here.
