ンのノズル。 A nozzle main body having a tapered conical spike formed at the center of the tip has a plurality of combustion gas flow passages each having a throat formed at the tip, the throat of each flow passage being the conical bottom of the spike. They are arranged at equal intervals on the same circumference with the spike as the center so as to open at each edge, and at the tip of the nozzle main body, the inner circumference of the base end coincides with the circumscribed circle of each throat section and is directed toward the tip. The conically expanding nozzle expansion portion is configured to include at least a high-density region of mutual combustion gas injected from each of the throat portions,
A jet engine nozzle characterized by being integrally formed.
