In this paper are presented a new results of testing traveling wave thermoacoustic (TAc) engine, coupled with alternating current magnetohydrodinamic (MHD) generator in FP7 project „Space Trips”. This project relates to experimental testing of radioisotopic-feeded electrical power supply system for deep Space applications. There are analyzed and described experimental graphs of thermoacoustic engine like pressure oscillation amplitude as a function of mean pressure and temperature. A certain extrapolation of them had been performed. Also a thermoacoustic excitation graph is plotted, where are shown critical values when acoustic power generation starts to generate soundwave.
