Fraunhofer Institute for Electronic Nano SystemsFluidic actuators are being used more and more frequently in a wide range of scientific areas and technology sectors and will play an important role in the future due to the optimal utility maximization of resources. Fraunhofer ENAS examines and develops various fluidic actuators for active flow control, taking into account the performance requirements from various fields of application. The developments focus on performance, a compact and functional integration as well as a smart and energy saving control of the actuators. Two main concepts are under development: actuators without pressurized air, the so-called synthetic jet actuators (SJA) and actuators with pressurized air, the pulsed jet actuators (PJA). By combining to modules for stackable mounting, the system is getting integrable and more compact. The surface of those modules can be adjusted to any geometry. In addition, such modules can be used for mounting of single actuators or even groups of actuators to increase the performance of the overall system and to make optimal use of existing installation spaces.
