Described simulation is a steady state computation taking advantage of Multiple Reference Frame model implemented in Ansys CFX. The paper includes an analysis of rotating domain thickness influence on numerical values of thrust and power. The results indicate that this type of simulation may be sensitive to the sizing of rotating domain especially when disc solidity is low, or when the number of blades is 2, a frequent situation in all electric flight vehicles. The analysis shows that performing simulations, using one domain sizing, for a number of flight scenarios requiring analysis of a few rotational speeds can produce unintuitive results. Therefore, it is suggested to calibrate the model, preferably by experimental results.enpropellerCFDelectric airshipUAVmanned flightexperimentśmigłoeksperymentelektryczny sterowiecArtykuł
