预冷却吸气式涡轮冲压膨胀循环发动机发展简介

A Study on the Components Used on Pre-cooled ATREX Engine

分析了吸气式涡轮冲压膨胀循环(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航空航天飞机第一级动力装置的要求。

Air turbo ramjet engine with expander cycle （ATREX） is a new type of high Mach turbine based combined cycle（TBCC） engine, based on existing turbojet engines developed in Japan. The authors analyze ATREX characteristics, explain its development superiority compared with the traditional engine, summarize its characteristics and key techniques in their development. It was found from the literatures that adopting liquid hydrogen cooler and pre-cooling method for ATREX engine can expand the regular turbojet working scope and satisfy the request of the supersonic aircraft or TSTO aircraft.
