Maneuverability is an important indicator for evaluating the comprehensive performance of aircraft, and the researchers have increasingly high requirements for the maneuverability of fighters. As target simulators, drones must possess corresponding maneuvering capabilities to replicate real combat scenarios. Based on the requirements of modern weapon testing systems and current trends in target drone technology, investigations into the development of supersonic high-maneuverability target drones was considered. Key performance metrics such as aerodynamic characteristics, structural integrity, and flight performance were tested. As a preliminary validation, development and flight testing of high-maneuverability, overload-capable target drones were conducted. For a drone with a total weight of 248 kg and a maximum flight speed of 0.8 Ma, the goal is to achieve a stable overload capability of over 6g and a maximum overload of over 9g. Firstly, CFD and CSD techniques were used to simulate the key performance of the aircraft, then flight tests were conducted for verification. The results indicate that the flight performance meets the overall design requirements and the simulation results agrees with it. The drone achieved complete autonomous control from take off to landing. The entire system performed reliably, and the drone maintained stable flight, with normal attitude, speed, altitude, and flight path tracking.
