ABSTRACT:
There is disclosed an anode for an electrothermal arcjet thruster. The anode includes a divergent nozzle having, in tandem, a recombination portion and an expansion portion. The expansion portion has a greater rate of divergence than the recombination portion. A regeneration channel containing flowing propellent gas extends internally within the anode adjacent the recombination portion. The combination of the biangle nozzle and the regeneration channel produces an arcjet thruster having a markedly increased thrust efficiency.
