This paper deals with the design and optimization of a 2.1 MW rim-driven electric thruster for ship propulsion. For this purpose, double stator ironless rotor axial flux permanent magnet (AFPM) motor is considered as propulsion motor. The analytical model selected AFPM presented. magnetic field in machine calculated using 3D charge concept combination image theory permeance functions to take in...

This paper presents some recent validation results with velocity-based source BEM analysis program as applied to prediction of cavitation on rudder and podded propellers. The RANS solver is also applied to modelling of the rudder behind the propeller and the both BEM and RANS numerical predictions are compared with the experimental data. An example of prediction of cavitation on podded propelle...

This manuscript discusses the operation of an electrically driven fan for a hybrid-electric propulsion system BAe-146 aircraft. The thrust requirement is fed into integrated cycle and aerodynamic design tool sizing ducted as one main propulsors, podded under wing replacement turbofan engine. electric motor initiated with torque speed requirements dimensional constraints arising from geometry. a...

The podded propulsor has gradually become an important propulsion device for high technology ships in recent years because of its characteristics maneuverability, efficiency, low noise, and vibration. performance is closely related to flow field. To study the unsteady field propulsor, DDES (delayed detached eddy simulation) method was used carry out high-precision transient numerical simulation...
