Most modern airplanes are powered with IC engines because electrical propulsion was
not feasible at the dawn of powered flight. It became viable only recently due to
advancements made on electric propulsion systems. Weight and space are key factors
for airplanes. Increasing the power density of the engine can enable the design of
more efficient and more powerful planes. One way to achieve this is to increase the
power level of the electric motor which also increases the power loss. In this case
more efficient cooling is needed to remove the excess heat. The aim of this paper
is to determine the optimal cooling solution for the stator of a radial flux permanent
magnet (PM) electric motor which is installed in an electric airplane. Computational
fluid dynamics (CFD) is used for the comparison of the developed concepts and their
sub-concepts. The results are detailed for every initial concept and then the three
best designs are chosen for further optimisation. Most modern airplanes are powered
