Abstract: Carried out the performance computation for blunt body scheme of Microwave Electrothermal Thruster (MET) The resonance model TM 011 and the waveguide model TM 01 were selected The N S equations of axisymmetric turbulent flow with blunt body under the action of electric magnetic field were used These models and equations were coupled with plasma area The computation results show that the tendencys obtained from the performance parameters of impulse and thrust etc coincide with the tests and the computation of reference
