Turbulent Boundary Layer Drag Reduction via Surface Actuators

The Defense Advanced Research Projects Agency (DARPA) is seeking 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 innovative solutions that actively modify turbulent flows to reduce drag on aerospace vehicles, thereby enhancing their performance in terms of range, endurance, speed, and payload. This initiative is particularly significant as even minor reductions in drag can lead to substantial improvements in operational capabilities, with potential applications in both military and commercial aviation. Interested parties should note that the solicitation is currently in the pre-release phase, with proposals due by June 25, 2025, and further details available at the official SBIR website.
