Abstract:
Active flow control devices such as zero-net-mass-flux actuators have broad aeronautical applications. Among them, low power and lightweight Synthetic Jet Actuators can be used to improve the performance of flight vehicles, providing load alleviation capabilities, expanding their flight envelope, and preventing catastrophic failure by aeroelastic instabilities. Numerical and experimental investigations are proving that SJAs are effective in actively altering the boundary layer; the effect of the momentum exchange due to the SJAs leads to a rearrangement of streamlines, a virtual aerodynamic shaping that enable changes in the aerodynamics forces acting on the lifting surfaces. This paper discusses development aspects that the authors have been conducting on the topic with applications to load alleviation and flutter suppression for aircraft wings.
