The design and performance of a four-ring three-phase ac ARC Heater are described. Successful operation at pressures of 10 to 33 atmospheres, temperatures of 2000 to 5000 degrees K and efficiencies of 25 to 60 percent has been demonstrated. Improvements in heater components will allow pressures of 70 atmospheres to be obtained. (Author).

A study of arc column rotation in a 4 ring ac arc heater without an external magnetic field is presented. Arc column speed is found to depend upon arc current, arc heater pressure, amount and direction of air injection and electrode geometry. The methods used for the experiments and the evaluation of the filmed data are described and justified. Arc heater efficiency and stability has been improved as a result of this work. (Author).
