The invention relates to the technical field of unmanned aerial vehicle power, in particular to a bimodal oil-electric hybrid aero-engine. The device is characterized by comprising an electric ducted fan, a flaring, a combustion chamber and an exhaust nozzle which are sequentially connected, the ducted fan is connected with the front end of the flaring through a first mounting edge arranged at the tail, the tail of the flaring is connected with the combustion chamber through a second mounting edge, and the combustion chamber is connected with the exhaust nozzle through a fourth mounting edge at the tail. Through the coupling of the electric ducted fan and the combustion chamber, the maximum thrust of the engine is improved on the premise of ensuring the endurance time, and the thrust range is expanded; the unmanned aerial vehicle has two modes of a cruising state and an augmentation state, in the cruising state, only the electric ducted fan is started to guarantee stable flight of the unmanned aerial vehicle, and in the augmentation state, the electric ducted fan and the fuel oil combustion chamber are started at the same time to generate larger thrust so as to meet the power requirements of maneuvering flight such as acceleration of the unmanned aerial vehicle.

    本发明涉及无人机动力技术领域,尤其涉及一种双模态油电混合航空发动机。其特点是包括依次连接的电动涵道风扇、扩口、燃烧室和尾喷管,所述的涵道风扇通过尾部设置的第一安装边与扩口前端相连,扩口尾部通过第二安装边与燃烧室相连,燃烧室通过尾部的第四安装边与尾喷管相连。其通过电动涵道风扇和燃烧室的耦合,在保证了续航时间的前提下提高了发动机的最大推力大小、扩大了推力范围;拥有巡航状态和加力状态两种模式,巡航状态下仅开启电动涵道风扇保证无人机平稳飞行,加力状态下同时开启电动涵道风扇和燃油燃烧室,产生更大的推力,以满足无人机加速等机动飞行的动力需求。
