The Defense Advanced Research Projects Agency (DARPA) is seeking proposals for the development of an Inertially Scaled Unmanned Aerial Vehicle (UAV) aimed at enhancing flight control development for subscale vehicles. The objective is to create a UAV weighing between 55 to 300 lbs that accurately mimics the dynamics of a target aircraft, allowing for early identification and resolution of flight control challenges, thereby reducing costs and risks associated with traditional aircraft development. This initiative is critical for improving the efficiency of flight control design and testing processes, ultimately benefiting both military and commercial aircraft programs. Interested parties must submit their Direct to Phase II (DP2) proposals by June 25, 2025, with the opportunity to leverage existing flight test data and designs to demonstrate feasibility and potential commercial applications.
