Резюме:

A High-Performance Ducted Propeller is an advanced propulsion configuration in which the rotor is enclosed within an aerodynamically optimized cylindrical duct. This design aims to increase propulsive efficiency by reducing tip vortex losses and improving control of the pressure distribution around the blades. By confining and guiding the airflow, the duct enhances thrust production, stabilizes the flow field, and reduces energy losses that typically occur at the blade tips in open propeller systems. A key advantage of the ducted configuration is its ability to provide superior low speed performance and higher static thrust, making it particularly valuable for applications such as vertical take-off and landing (VTOL) aircraft, unmanned aerial vehicles (UAVs), marine thrusters, and other propulsion systems requiring efficiency and precision at low forward velocities. The duct also contributes to significant noise reduction by shielding the rotor, improving operational safety and acoustic performance. Furthermore, the local flow field around the rotor–duct system can be tailored through geometric optimization, allowing them to achieve specific performance objectives such as minimizing drag, enhancing pressure recovery, or controlling flow separation. In overall, the integration of a duct around a propeller represents a critical design approach for modern high-efficiency propulsion systems. Its combined benefits— enhanced thrust, reduced losses, improved stability, and lower noise—make it a promising solution for next-generation aerospace applications.
