The concept of a semi-morphing wing is presented. Instead of elastically deforming the structure the adaptation of the wing geometry to the flight conditions is achieved by means of the deflection of a high number of complementary and redundant classical wing control surfaces. A complex flight controls system is designed to allow using these control surfaces as multi-objective devices, addressing in parallel aerodynamic efficiency, loads alleviation, and vehicle control while still ensuring safety of operation by means of appropriate flight control laws re-configuration in case of failures. The paper presents the benefits for the case of a turboprop driven regional aircraft.
