v405s754p44	Grady Charles Crahan	Turret Optimization Using Passive Flow Control to Minimize Aero-Optic Effects	2014		.txt	text/plain	426	13	33	The investigation shows that the virtual duct technique is an effective passive flow-control approach for dealing with aero-optic flows on spherical turrets in subsonic to transonic flows. By the use of optimization techniques along with experimental validation, it is shown that significant increases of delaying flow separations up to an elevation angle of 162.4° while maintaining a critical Mach number over 0.7 can be attained on a hemispherical turret without a downstream fairing.	cache/v405s754p44.txt	txt/v405s754p44.txt
