Not Available Structural responses to gust and buffet load excitation encompass a wide range of frequency spectrum. Any load alleviation system must be able to function well beyond this range to provide necessary damping to suppress vibrations. The proposed load alleviation system has the following unique qualities: 1. It uses aerodynamic damping property to suppress the structural responses, 2. It uses the smart actuation system to activate/excite the aerodynamic effectors to generate unsteady air loads, 3. The actuators have large magnification factors so as to limit strains of piezoelectric materials within safe margins, 4. Aerodynamic effectors deform continuously and smoothly providing efficient aerodynamic authority, 5. Piezoelectric actuators operate in kilo Hertz range and are able to cover a wide range of the excitation spectrum.
