BURNABLE NOZZLE OF RAMJET

摘要

FIELD: engines and pumps.SUBSTANCE: burnable nozzle of ramjet is arranged inside mid-flight nozzle and composed of two interconnected elements to make acceleration mode nozzle in acceleration from subsonic to transonic and from transonic to supersonic ranges. Lengthwise ducts plugged on the side of afterburner to make a set of pylons are arranged at outer side of nozzle elements and secured to engine mid-flight nozzle inner surface. Nozzle elements are made of material wit high thermal erosion resistance to combustion products with reduction chemical potential and low thermal erosion resistance to combustion products with oxidation chemical potential.EFFECT: higher reliability of burnable nozzle in acceleration mode and efficiency of mid-flight nozzle in ramjet mode.4 cl, 3 dwg
