摘要
结合热力循环过程建模和数值模拟分析方法,构建了基于SABRE技术的佩刀发动机方案并对发动机特性进行分析。根据发动机模态特点和特性优势,综合文献资料,对佩刀发动机的飞行器应用方式进行了分析。分析认为,佩刀发动机有希望为多种飞行器应用方向提供动力,包括为临近空间巡航飞行器和亚轨道载荷发射/投放、空天入轨等飞行器提供动力。
A SABRE cycle model is reconstructed with the method of thermodynamic cycle analysis combined with CFD simulations. Considering characteristics of airbreating and rocket modes and advantages of thrust to weight and specific impulse of SABRE engine required by a horizontal takeoff,reusable aircraft,some possible vehicle applications are provided and analyzed with published documents reviewed and taken into consideration.It reveals that the SABRE engine may be used to different horizontal takeoff vehicle applications,meaning which might be used not only to propel hypersonic cruise vehicle with pure airbreathing mode,but also to propel a suborbital vehicle lifting off an orbit or a striking payload in suborbital space,or to propel a TSTO vehicle to a higher Mach separating point with working in both airbreathing and rocket modes.
