Overview
Flap systems are highly efficient lift providing elements in low speed flight. A potential measure to shift the stall onset to higher limits can be found in an Active Flow Control (AFC) approach by pulsed blowing. The majority of corresponding research aims at understanding the aerodynamic phenomenon allowing broad bandwidth investigations to find optimum configurations. In this proposal the systems aspects were addressed with respect to the active flow control actuator system. The overall system integration was performed by the SFWA partner EADS-IW with support provided by TUB through this project.

Flap systems are highly efficient lift providing elements in low speed flight. A potential measure to shift the stall onset to higher limits can be found in an Active Flow Control (AFC) approach by pulsed blowing. The majority of corresponding research aims at understanding the aerodynamic phenomenon allowing broad bandwidth investigations to find optimum configurations. In the course of this project the systems aspects were addressed with respect to the active flow control actuator system. For that a core flow control actuator system is required, which is sufficiently robust while providing high control authority to fulfil the requirements imposed on an aircraft scale application.
This core actuator system was developed and matured by TUB in the project DT-FA-AFC and integrated into the overall flow control architecture within FloCoSys in close cooperation with SFWA partner EADS-IW and with continuous exchange with the partners in CfP project AFCIN. The efforts lead to the successful test of an aircraft scale flueric (incorporating no moving or electrical components) flow control system, which was extensively tested at EADS-IW's site in Ottobrunn. The insights gained from those tests furthered the understanding of the necessities of a civil aircraft flow control system. The work provided input for ongoing SFWA CfP project robustAFC.
