Paper Abstract

We discuss the design and analysis of an actuator system to deform awing over its entire cross section so that optimum aerodynamic shapes can be realizedfor more than one flight condition. Preliminary aerodynamic analyses indicate that thisconcept could reduce the drag coefficient of the JSTARS wing by at least 6% duringloiter; however, aerodynamic design optimization is required to quantify theimprovement. A test model of an active rib is being constructed. Finite-element analysisof this model indicates that the system will accurately produce desired deformed shapes.
