Electric arc type propulsion motor

Claim 1

AN ELECTROTHERMIC JET MOTOR COMPRISING, IN COMBINATION, AN ARC CHAMBER, A FIRST AND SECOND ELECTRODE DISPOSED IN SAID ARC CHAMBER, SAID ELECTRODES BEING IN LINE WITH EACH OTHER AND SEPARATED BY A GAP TO PROVIDE AN ARC DISCHARGE THEREBETWEEN, AN INLET FOR A WORKING FLUID, A CAVITY IN SAID FIRST ELECTRODE LOCATED IN THE FOREMOST PART OF SAID FIRST ELECTRODE ADJACENT SAID GAP, PASSAGEWAY MEANS FOR TRANSPORTING SAID WORKING FLUID FROM SAID INLET INTO SAID CAVITY AND ADAPTED TO PROMOTE HEAT EXCHANGE BETWEEN SAID FIRST ELECTRODE AND SAID WORKING FLUID, A CONCENTRICALLY DISPOSED REFRACTORY ROD IN SAID CAVITY, FLUID DISTRIBUTION MEANS SURROUNDING SAID ROD AND ADAPTED TO EMIT SAID WORKING FLUID INTO SAID GAP SUBSTANTIALLY PARALLEL TO THE SURFACE OF SAID FIRST ELECTRODE, SAID SECOND ELECTRODE HAVING A JET NOZZLE THEREIN WHOSE AXIS OF SYMMETRY SUBSTANTIALLY COINCIDES WITH THE DIRECTION OF PROPAGATION OF SAID ARC DISCHARGE, SAID NOZZLE BEING ADAPTED TO CONVERT THERMAL ENERGY INTO KINETIC ENERGY.
