According to the three-channel parallel-connection turbine stamping combined engine, an outer duct is formed between a stamping machine box and a middle machine box, a middle duct is formed between the middle machine box and a turbine machine box, and an inner duct is formed in the turbine machine box; and therefore, a three-duct parallel structure form is formed. Moreover, airflow distribution between the outer duct and the middle duct can be adjusted by adjusting the working position of the duct converter, the working state of each combustion chamber is cooperatively controlled, and in the process of acceleration from takeoff to hypersonic flight, switching of the turbo-ramjet combined engine among four different working modes can be achieved, and the working efficiency of the turbo-ramjet combined engine is improved. Compared with an existing turbine ramjet combined engine, two intermediate working modes are added, so that an aircraft can conduct intermediate state cruising work, the overall oil consumption of the engine can be reduced, and the turbine ramjet combined engine can be well suitable for civil hypersonic aircrafts.

    本发明公开了一种三通道并联的涡轮冲压组合发动机、飞行器,所述三通道并联的涡轮冲压组合发动机通过在冲压机匣与中间机匣之间形成外涵道、在中间机匣与涡轮机匣之间形成中涵道、在涡轮机匣内形成内涵道,从而形成三涵道并联的结构形式。并且,通过调整涵道变换器的工作位置可调节外涵道和中涵道之间的气流分配,并配合控制各个燃烧室的工作状态,在从起飞加速至高超声速飞行的过程中,可以实现涡轮冲压组合发动机在四种不同工作模式之间的切换,相比于现有涡轮冲压组合发动机,增加了两种中间工作模式,以便于飞行器进行中间状态巡航工作,而且有利于降低发动机的整体油耗,可以很好地适用于民用高超声速飞机。
