CFD Used to Improve Missile Control

	Posted Fri August 13, 2004 @04:43PM
	A new desktop engineering article covers the development of a novel flow control system for missiles using actuators and advanced control algorithms. Instead of traditional hinged control surfaces, the aerodynamic surface contains an embedded system of miniature sensors on the outer surface, control actuators, and a real-time feedback controller just below the surface, all of which are unseen from the exterior. Displacement of the actuators creates a large effect on the flowfield around that region. To validate its research findings and test active flow control system prototypes, ORI’s Aerodynamics Group relies on low- and high-speed wind tunnel tests and CFD simulations. "By combining CFD analysis with wind tunnel experiments," Patel explained, "we are able to reduce the total turnaround time for feasibility studies as well as systems development." Read the full article for more details.
