Abstract: This paper presents the development of a cooling concept for an electric propulsion system of an aerobatic aircraft. The numerical part of this paper focuses on the battery cooling performance requirements, the internal design of the cooling duct and their influence on heat transfer efficiency, using conjugate heat transfer (CHT) simulation. The analysis was performed with the computational fluid dynamics (CFD) code Ansys CFX, using a Shear Stress Transport (SST) model. It is planned to prove the cooling concept in a full scale wind tunnel test. The test preparation is also described in this paper.
