ABSTRACT:
A thrusting nozzle (24) comprises an annular shell (34) and an inner body (30). The contours of the inner wall (42) of the shell (34) and the outer wall (44) of the inner body (30) form a convergence zone (48), a throat (50), and an outlet zone (52) in sequence from the nozzle inlet (54) to the nozzle outlet (56). The inner body (30) extends from the upstream end of the nozzle to a point downstream of the throat (50). In the convergence zone (48), the cross section area of the flow passage continuously and gradually decreases from the nozzle inlet (54) to the throat (50). In the outlet zone (52), the cross section area of the flow passage can gradually increase from the throat (50) to the nozzle outlet (56). The nozzle (24) can be mounted as part of a jet engine (10), with the nozzle inlet (54) being connected directly to the discharge of a gas turbine (22). The contours of the inner wall (42) of the shell (34) and the outer wall (44) of the inner body (30) are suitable for producing a continuous acceleration of gas velocity from the nozzle inlet to the nozzle outlet, with a sonic gas flow rate in the throat and a supersonic gas flow rate at the nozzle exit for gases having a sufficient pressure differential for the configuration between the nozzle inlet and the nozzle outlet.
