The invention belongs to the technical field of aviation aircrafts, and particularly relates to an aero-engine and an aviation aircraft. The invention provides an aero-engine which comprises two sets of mixed circulation units, a combustion chamber and an adjustable spray pipe, the two sets of mixed circulation units are axially arranged front and back, a flow channel switching assembly is arranged between the mixed circulation units, and outlets of the mixed circulation units communicate with the combustion chamber and the adjustable spray pipe in sequence. The invention further provides an aircraft comprising the aero-engine. In the technical scheme provided by the embodiment of the invention, the two groups of hybrid cycle units are axially arranged front and back, and the serial-parallel connection mode of the two groups of hybrid cycle units is adjusted through the flow channel switching assembly, so that the wide supercharge ratio required by different flight speeds is realized; meanwhile, the two groups of hybrid cycle units work continuously, the problem of partial structure waste does not exist, and the aero-engine is simple in structure; the technical defect that in the prior art, the wide speed range and the simple structure of an aero-engine are difficult to consider is overcome.
本申请属于航空飞行器技术领域,尤其涉及一种航空发动机及航空飞行器。本申请提供了一种航空发动机,包括:两组混合循环单元、燃烧室以及可调喷管,两组混合循环单元轴向前后设置,混合循环单元之间设置有流道切换组件,混和循环单元的出口依次与燃烧室和可调喷管连通。本申请还提供了一种包括上述航空发动机的航空飞行器。本申请实施例提供的技术方案中,两组混合循环单元轴向前后排布,通过流道切换组件调整两组混合循环单元的串并连模式,实现了不同飞行速度所需的宽增压比;同时,两组混合循环单元均持续工作,不存在部分结构浪费这一问题,航空发动机结构简单;解决了现有技术中,难以兼顾航空发动机宽速域以及结构简单的技术缺陷。
