Subject of this work is the investigation of the impact of inlet distortions on helicopter gas turbines. These small turboshaft engines encounter a wide field of inhomogeneous inlet flows as a result of their specialized usage. By using the Matlab/Simulink® tool-box Toolbox for the Modeling and Analysis of Thermodynamic Systems (T-MATS) a performance calculation tool is implemented to predict the impact of a distortion to the engines thermodynamic cycle. In its first version, presented in this paper, it is able to address total pressure distortions, but the approach taken will also be able to treat temperature distortions later on. To confirm the calculated results a series of tests were executed on a helicopter engine test bed, which includes a common small turboshaft engine for around 300-600kW shaft power used in light twin-engine helicopters.
