预冷却ATREX发动机主要部件发展研究

Development Study on Primary Components of the Pre-Cooled ATREX Engine

文中分析了 ATREX 发动机模型和工作原理,介绍了其主要部件的研究和发展情况,与常规发动机相比说明了其发展的优势,总结归纳了这种发动机技术特点和发展的关键技术。研究认为 ATREX 发动机采用液态氢预冷却方式,大大扩展了常规涡轮发动机的工作范围,可满足高速飞行器或两级入轨空天飞机第一级动力装置的要求。

This paper analyzed to ATREX the work characteristics,explained its development advantage compare with the general engine,the summary induced this kind of engine technique characteristics and the key technique of the devel- opment.Drawing a conclusion by referencing the document published from aboard,similar to the ATREX,adopting liquid hydrogen cooler and pre-cooled method,can expand the regulations turbojet work scope consumedly,can satisfy the request of the supersonic aircraft of TSTO aircraft of the first stage equip.
