摘要

为了拓展冲压发动机的性能,文中提出了一种喷雾预冷措施,用以冷却高温压缩来流、增加做功工质,以期提升发动机的推力水平。同时建立模型对这一性能拓展概念进行了分析。结果表明:喷雾预冷提升了冲压发动机的热循环效率和推力水平,拓展了发动机的工作上限;但喷雾给发动机附加了额外的消极质量,影响了比冲性能;在高速来流条件下,喷雾预冷作为一种性能拓展和推力调控手段,更具积极意义。

Abstract

A performance promotion concept which adopts pulverization to pre-cool compressed air flow and increase working substance was presented to improve performance of ramjet in the paper, and a theoretical model was established to analyze this promotion concept. It is concluded that pre-cooling compressed air flow by means of pulverization can improve heating efficiency and thrust level, extend upper working limit of ramjet, but negative weight of pulverization added to ramjet can affect specific impulse; pre-cooling compressed air flow by means of pulverization has effective significance for ramjet in high-speed flight application.

Key words： ramjet; pulverization; pre-cooling; compressed flow; performance promotion
