This master thesis is focused on design and aerodynamic analysis of subsonic turbine engine inlet in NACA duct configuration for unmanned aircraft. The first part of this paper is methodics for design considerations for NACA duct, which is based on theoretical analysis of this type of inlet. The acquired knowledge is used to design an inlet for the specified unmanned aircraft that is subject of CFD analysis. The impact of deflectors is considered in the evaluation and the solution is compared to the S-duct inlet. The proposed inlet with deflectors meets DC60 distortion criterion for all specified cases and the pressure losses requirements are met for lower velocities. Based on the results, the recommended application is for aircraft that flies in optimal design conditions for most of the mission.
