University of Maryland, College Park, Alfred Gessow Rotorcraft Center
CeFPaC Experience:
Rotorcraft Aeromechanics, Advanced Rotary-Wing Configurations:
Conventional helicopters, high-speed configurations (coaxial/compound helicopters, tiltrotors), variable-RPM rotors, swashplateless rotor helicopters and multi-copters. Passive design optimization, active and semi-active controls; for helicopter vibration reduction, aeroelastic and aeromechanical stability augmenation, blade-vortex interaction alleviation, and performance improvement; exploitation of control redundancy, and fault-tolerant control.
Morphing Rotorcraft Systems:
Variable rotor blade twist/camber, span, and chord; airfoil reversal; studies on performance improvement and increase in aircraft capability, concepts for actuation implementation, flight simulation studies; modular and reconfigurable rotary-wing aircraft designs.
Smart Materials and Structures:
Shape Memory Alloys/Polymers, Electro- and Magneto-rheological fluid dampers and devices, Piezoelectric actuators and Active Constrained Layer Treatments – for structural vibration reduction and damping augmentation. Flexible skin designs for morphing aircraft wings. Variable Stiffness Structures, Multi-Functional Cellular Structures, and Multi-Stable Structures.
