Turbulent Boundary Layer Drag Reduction via Surface Actuators

The Defense Advanced Research Projects Agency (DARPA) is soliciting proposals for the Small Business Innovation Research (SBIR) program focused on "Turbulent Boundary Layer Drag Reduction via Surface Actuators." The objective is to develop and flight test an actuator system capable of reducing turbulent boundary layer drag, which is critical for enhancing the performance of aerospace vehicles and weapon systems. This initiative aims to leverage innovative techniques, such as plasma-based drag reduction, to achieve significant improvements in fuel efficiency and overall system capabilities. Proposals are due by June 25, 2025, with a focus on demonstrating feasibility through laboratory-scale evidence and a clear path to flight testing.
