Arcjet Stage Investigation and Inductive Hydrogen Heating in the TIHTUS Engine

The water-cooled laboratory model of the two-stage hybrid thruster TIHTUS is briey explained and results of investigations of each stage are presented. Thrust measurements of the arcjet stage yield a maximum thrust of 3.3 N and a maximum specic impulse of 1430 s with the curves showing no sign of saturation. Hydrogen operation at the inductively coupled stage is presented showing an eciency of plasma heating of 32% and a thrust of over 2.3 N is estimated at a specic impulse of lower than 400 s. Theoretical investigations of magnetohydrodynamic (MHD) eects within the inductive stage are presented. From the obtained terms for magnetic pressure and Lorentz force an optimization tool for inductively heated plasma sources was derived.
