One challenge has been to develop a low frequency, lightweight actuator that can provide large displacements. This study will discuss the modeling, design, manufacture, and testing of a bimorph piezo-composite actuator that will provide such displacements at low frequencies. The design employs two opposing benders that provide a piston-type motion. The initial goals of this study were to achieve 30 m/s out of the slot while maintaining the mechanical resonant frequency of the system at about 100 Hz. 2897244 bytes application/pdf en_US RESONANCE BASED LOW FREQUENCY SYNTHETIC JET ACTUATOR MODELING, DESIGN, AND TESING Thesis Engineering, Aerospace Engineering, Aerospace synthetic jet piezo actuator recurve open.access
