摘要: 提出了一种固液相变冲压发动机概念,即在常温下存放时燃料为固体状态,工作时通过微波驱动相变为液体,该发动机改善了液体冲压发动机的某些缺点。文中阐述了固液相变发动机原理,建立了固液相变燃料概念,提出了该类发动机评价体系指标,同时对该类发动机设计技术、相变驱动技术、相变燃料特性以及可能的应用领域进行了阐述和分析,对采用双下侧进气道的原理样机进行了地面模拟条件试验。以直链烷烃为主的相变燃料存放安全、成本低、不怕玻璃化,适合极低温环境存放和使用。

Abstract: A novel ramjet based on solid-liquid phase change fuels is proposed. The fuels are solid before operation or during storage conditions and are driven from solid to liquid at operation state through microwave radiation. It improves some of the disadvantages of liquid ramjet. The principle of solid-liquid phase change ramjet is described, the concept of solid-liquid phase change fuels is established, and the index of this kind of ramjet evaluation system is put forward. The design technology of this kind of ramjet, the drive technology of phase change, the characteristics of phase change fuels,and the possible fields of application are described and analyzed. A double lower inlet ramjet based on solid-liquid phase change fuels has been demonstrated at ground tests. The phase change fuels mainly based on straight chain alkane can be stored safely with lower cost, are not afraid of glass transition, and are more suitable to be stored and used in extremely low temperature environments.

Key words: solid-liquid phase change fuels, ramjet, microwave drive phase change, low cost fuels, straight chain alkane
