Paper Abstract

The SMAAC control surface concept is an adjustable camber foil which isactuated by shape memory alloy wires to control flight of hydrodynamic or aerodynamicvehicles. An operational model of a SMAAC control surface was fabricated anddemonstrated in a water tunnel. Lift measurements in the water tunnel indicated that theSMAAC foil produces 40% higher lift force than rigid foils at.the same angle of attack.Flow visualization showed that the wake behind a SMAAC foil was a factor of 3 smallerthan the rigid foil at equivalent lift. The next generation SMAAC design is presented.
