    Abstract In recent years, electric Vertical Take-Off and Landing aircraft (eVTOL) have been increasingly researched and developed because of their high applicability: parcels and deliveries, rescue, military, etc. These flying machines typically use an Electric Ducted Fan (EDF) driven by an Electric Motor located within the Centre Body of this EDF. In this study, several ventilation hole concepts on the Centre Body were given to increase the cooling ability of the Electric Motor. Two-way heat transfer method were implemented to simulate the conductive and convective heat transfer phenomenon between the Computational Fluid Dynamics and Finite Element models in the cases with and without the ventilation holes. The validation of the model’s accuracy was done by comparing separately the simulation results of the EDF and the Electric Motor with the experiment data and the previous research result, respectively. The results show that the most effective ventilation hole configuration has reduced the temperature of the Rotor, End-Winding Forward, and End-Winding Rear respectively 6.66 °C, 5.54 °C, and 6.8 °C.

    Purpose This study’s investigation aims to clarify the effect of an additional geometry, i.e. a fillet radius, to the blades of a single-stage transonic axial compressor, NASA Stage 37, on its aerodynamic and structural performances. Design/methodology/approach Applying the commercial simulation software and the one-way fluid–structure interaction (FSI) approach, this study first evaluated the simulation results with the experimental data for the aerodynamic performances. Second, this paper compared the structural performances between the models with and without fillets. Findings This research analyses the aerodynamic results (i.e. total pressure ratio, adiabatic efficiency, stall margin) and the structural outcomes (i.e. equivalent von Mises stress, total deformation) of the single-stage transonic axial compressor NASA Stage 37. Originality/value This paper mentions the influence of blade fillets (i.e. both rotor hub fillet and stator shroud fillet) on the compressor performances (i.e. the aerodynamic and structural performances).
