This invention relates to the propulsion system of an aircraft. It utilizes a liquid fuel prevaporization and back burning induction jet oval thrust nozzle which is fitted onto the exit nozzle of a conventional turbojet engine having a ram constriction air inlet plenum-engine pod located forward of the aerodynamic generating channel. The aerodynamic generating channel is located forward and above a vacuum cell induction lift wing and below recycling air inductor vanes.
