超燃冲压发动机推阻力特性研究综述

Investigation of thrust/drag property of scramjet

超燃冲压发动机由进气道、燃烧室和尾喷管等部件构成,推阻力是其最重要的特性参数。回顾了超燃冲压发动机部件级推阻力特性和整体推阻力特性研究现状,介绍了超燃冲压发动机推阻力特性研究方法和测量技术。建议今后研究过程中关注以下几个问题:研究精确的自由射流试验测量技术,研究流场均匀性对发动机性能的影响,开发高精度仿真平台。

Thrust and drag are the most important characteristic parameters ot scramJet, WlllCh consists of inlet, combustor and nozzle. The research status of the component-level and the overall thrust/drag characteristics are reviewed in this paper. The research methods and measurement technology for the thrust/drag characteristics of scramjet are introduced. Some suggestions are proposed for the future study： investigating the accurate free-jet test measurement technology, investigating the impact of the flow field uniformity on scramjet performance, and developing the high-precision simulation platform.
