摘要
对环形喷管的概念、特性、分类及其应用作了详细说明，介绍了国内外环形喷管的研究概况，并分析了环形喷管在实际应用中会遇到的问题及解决方法。
Explains the concept,characteristics,type and application of annular nozzle in details,concisely introduces the research situation of annular nozzle at home and abroad and describesproblems and their solutions appearing in practical application of annular nozzle. All theory research,cooled-flow test and firing test indicate that annular nozzles are much shorter and lighter compared toconvention nozzles in same expand ratio. Annular nozzles can automatically adapt the change ofenvironment pressures,so they always maintain high efficiency in different altitudes. Because of thepossibility to realize the material and structure of annular nozzles, the concept of annular nozzles isbrought up again and concrete metheds are established. Therefore,they are applicable and perspectiveto improve the thrust and impuls of rocket motors in the future.
