Abstract

In this paper are presented a new results of testing travelling wave thermoacoustic (TAc) generator, 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 analized and described experimental graphs of thermoacoustic generator 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.
