Abstract

This paper outlines a methodology for assessing the integral characteristics of a generic scramjet with an integrated propulsion system (PS). The specific impulse and heat flows in the PS for X-43 and X-51 scramjets are calculated. The results obtained are in good agreement with the estimates of other authors (in the speed range 5 < M < 10), as well as with the known graphs of the specific impulse dependence for various types of engines depending on the flight Mach number and the type of fuel used.

论估算具有综合推进系统的通用 Scramjet 整体特性的方法

摘要本文概述了一种评估带有集成推进系统（PS）的通用扰流喷气机整体特性的方法。计算了 X-43 和 X-51 加力燃烧喷气发动机的比冲和 PS 中的热流。所获得的结果与其他作者的估计值（速度范围为 5 < M < 10）以及各种类型发动机（取决于飞行马赫数和所使用的燃料类型）的比冲依赖性已知曲线图非常一致。
