Effect of Radial Gap between the Ring and Propeller Tips on the Performance of a Ducted Propeller

The effect of the gap between the propeller tips and the inner wall of the duct ring on the thrust and available capacity of the ducted propeller propulsion system is investigated. The structure of vortex flow in a thin gap between the end surface of the propeller blades and the air ring of the duct...

Zusammenfassung:The effect of the gap between the propeller tips and the inner wall of the duct ring on the thrust and available capacity of the ducted propeller propulsion system is investigated. The structure of vortex flow in a thin gap between the end surface of the propeller blades and the air ring of the ducted propeller is analyzed, as well as the features of the propeller blades flow at boost modes.
