摘要

超燃冲压发动机是当前高超声速飞行器的主流动力系统。高超声速飞行器长时间、高马赫数飞行时发动机热防护需求与用电需求显著。针对某型号超燃冲压发动机，设计了一种基于超临界CO

布雷顿循环的冷却与发电一体化系统；构建了发动机的壁面热源表征模型，探究了吸热压力、透平入口温度、放热压力和回热度等关键设计参数对系统热力性能的影响规律及参数间的耦合关系；采用多参数协同优化方法，获得了冷却与发电一体化系统的最佳设计方案与最优性能，并以传统简单循环作为基准方案进行对比，评估了本方案的热力性能优势。结果表明：该冷却与发电一体化系统的最高发电效率可达15.9%，可实现206.2 kW的持续电力供应，表现出较好的应用潜力；发动机壁面吸热过程夹点温差越小，本方案相对基准方案的热力性能优势越显著，发电效率的最大相对提高量可达9.3%。

Abstract

Scramjet engines are mainstream power systems for hypersonic vehicles

and it has significant thermal protection demand and power supply demand during the long-time and high-Mach-number flight of hypersonic vehicle. An integrated cooling and power generation system based on supercritical CO

Brayton cycle is designed for a certain type of scramjet engine. The characterization model of wall heat source for this scramjet engine is constructed. The influences of key design parameters

such as heat absorption pressure

turbine inlet temperature

heat release pressure

and regeneration degree

on the system therm

odynamic performance are investigated

as well as the coupling relationships among various design parameters. The optimal design schemes and performance of the integrated cooling and power generation system are obtained by the multi-parameter collaborative optimization. The thermodynamic advantages of the proposed system are also evaluated by comparing with the conventional system with a simple cycle as the baseline. The results show that the proposed integrated cooling and power generation system can achieve a maximum power generation efficiency of 15.9% and a continuous power supply of 206.2 kW

which exhibits a good potential for actual application. The smaller the pinch temperature difference during the heat absorption process of the engine wall

the more significant the thermal performance advantage of the proposed system compared to the benchmark scheme

and the maximum relative increase in power generation efficiency can reach 9.3%.
