基于第二动力技术的TBCC综合能源展望

飞行器电能、液压能和气压能的功率需求由第二动力系统单独做功或提取发动机主轴功率供应。TBCC发动机模态转换后,第二动力系统无法从发动机主轴提取功率。因此,需要解决空天飞行器第二动力系统长时间大功率能量输出的问题。分析航空蓄电池、起动发电机、APU、GTS、ATS和RAT的技术特点、发展现状以及第二动力的发展趋势,结合高超声速飞行器的发展趋势,提出ATS/RAT组合和多电超导发动机/大比能的储能装置技术组合是实现空天高超声速飞行器综合能源的技术路线。

The outlook of TBCC integrated energy based on the secondary power system

The electrical generation, hydraulic power and pneumatic power of an aircraft is supplied by the secondary power system or the power extracted from engines by the secondary power system. After the mode transition of TBCC, there is no energy from engines for extracting. Therefore, it is needed to solve the problem of long time and high energy output of the secondary power system for airspace hypersonic aircraft. The technical features, application and development of the secondary power system is concluded in this paper, as well as the development of hypersonic aircraft. The combination of ATS & RAT and superconducting generator of more electric engine technology & large energy storage devices are available technical routes for integrated energy of airspace hypersonic aircraft .
