Research on Preliminary Integrated Design of Electric Ducted Fan

Electric ducted fans are widely used in hybrid aircraft, electric aircraft, and VTOL vehicles. The future development of ducted fans will focus on achieving high power density, higher cruise speeds, longer battery life, and increased task load capacity. Under the conditions of specified tension and motor power constraints, the ratio of hub to blade tip and the ratio of inner and outer diameters of the motor stator are introduced to analyze the performance of the propulsion system in this paper. And this article mainly studies the relationship between the static thrust of the fan, motor power, and motor temperature rise, and proposes the direction for optimizing the design of duct fans based on the relationship between these three factors.
