Energy Saving via Integrated Passive and Active Morphing During Maneuvers

Abstract

This paper presents some novel results found using integrated passive and active morphing during different helicopter maneuvers. A nonlinear, rigid blade helicopter model is linearized around three different maneuvering flight conditions. A specific variance constrained controller namely OVC is applied for flight control system. Parameters of autopilot and morphing parameters are simultaneously determined in order to minimize control energy while there are constraints on helicopter and control design parameters. A stochastic optimization method is used for this purpose. Closed loop system response analyses are done in order to see superiority of integrated passive and active morphing with respect to nominal helicopter and existing two morphing approaches.
