摘要:

本文对涡扇冲压组合发动机的等q特性作了初步的分析探讨.对涡扇冲压组合发动机的工作接力点马赫数作了定量的计算.并提出了估算接力点马赫数的方法.还对不同等q值下的燃烧室静温、静压、空气流量及推力进行了分析.本文提供的数据可供涡扇冲压组合发动机设计参考.

Abstract:

The ATR/RJ combined engine performance at constant dynamic pressure is analyzed.Based on the data, the transition condition is considered and calculated. Also, the static temperature, static pressure in combustor, airflow rate and thrust under the condition of various dynamic pressure were compared respectively.All the performance parameters presented in the paper are useful for the design of the airturborocket/ramjet combined engine.
