The invention belongs to the technical field of engine exhaust, and particularly relates to an engine exhaust system and an aircraft. The exhaust system comprises an engine main spray pipe, a mixing pipe, a flow deflector and a flow deflector mounting bracket; the tail part of the engine main spray pipe extends into the mixing pipe; the diameter of the tail of the engine main spray pipe is smaller than that of the mixing pipe, and an injection area is formed between the tail of the engine main spray pipe and the mixing pipe. The engine power cabin is connected to the outer side of the mixing pipe, and heat of the power cabin is dissipated through injection airflow of the injection area. A flow deflector is mounted in the mixing pipe through a flow deflector bracket; the two ends of the flow deflectors are hinged to the flow deflector supports respectively in the direction perpendicular to the airflow direction; the tail ends of the flow deflectors in the airflow direction are connected with an adjusting mechanism to drive the flow deflectors to deflect, airflow distribution on the two sides of the flow deflectors is adjusted through deflection of the flow deflectors so as to adjust the injection amount on the two sides of the exhaust pipe, and therefore the heat dissipation speed of the power cabin is adjusted.

    本发明属于发动机排气技术领域,具体涉及一种发动机排气系统及一种飞行器,排气系统包括:发动机主喷管、混合管、导流片、导流片安装支架;所述发动机主喷管尾部伸入混合管内;所述发动机主喷管尾部直径小于混合管直径且发动机主喷管尾部与混合管之间构成引射区;发动机动力舱连接在混合管外侧,通过引射区的引射气流为动力舱散热;所述混合管内部通过导流片支架安装导流片;所述导流片沿垂直于气流方向两端分别与导流片支架铰接;所述导流片沿气流方向末端连接调整机构以驱动导流片偏转,通过导流片偏转调整导流片两侧的气流分布以调整排气管两侧的引射量,从而调整动力舱的散热速度。
