摘　　要：涡轮基组合循环发动机(turbine based combined cycle engine, TBCC)通过涡轮与冲压的有效组合,大幅拓展了传统涡轮发动机与冲压发动机的工作包线,最高工作马赫数达到4.0及以上,是航空与航天领域重要的研究发展方向。以临近空间高速飞行器对动力装置的发展需求为牵引,研究了国外TBCC发动机近十年来的典型案例和发展趋势,并对TBCC发动机试验技术的主要进展进行了分析。研究表明:国外具有良好的直连试验和自由射流试验技术基础,已完成地面整机集成和模态转换试验,技术成熟度达到4~5级,并规划了飞行试验验证工作。建议我国注重理论与试验技术的结合,逐步提升关键技术成熟度,创造社会经济效益。Turbine based combined cycle engine expands the working envelope of traditional turbine engine and ramjet engine through the effective combination of turbine engine and ramjet engine, which is an important research and development direction in the field of aviation and aerospace.The maximum working Mach number is above 4.0.Based on the operational requirements of hypersonic aircraft in near space, this paper studied the typical cases and development trend of TBCC engine abroad in recent ten years, and analyzed the main progress of TBCC engine test technique.The results show that foreign countries have a good foundation of direct connection test and free steam test technology, and have completed the integrated ground machine and mode transition test, and technical maturity have reached TRL 4-5, and planned the flight test verification work.It is suggested that China should pay attention to the combination of theory and test technology, gradually improve the maturity of key technologies, and create social and economic benefits.
