Experimental and theoretical investigations into the technology associated with three-phase AC arc heaters is presented and critically discussed. The behavior of the three-phase arc is extensively considered and it is shown that a previously reported analysis can adequately predict this behavior. The problems of designing arc heater components are discussed and in particular those associated with the pressure vessel. It is shown that the present, low pressure chamber extracts an unacceptable amount of energy from the arc heated gas resulting in a rather low unit efficiency. Finally, the benefits which might result from coupling a magnetogasdynamic accelerator to the arc heater for flight simulation are discussed and on the basis of perfect accelerator performance no losses it seems that significant increases in stagnation properties can be effected.
