The invention relates to an aircraft engine air inlet channel and an aircraft comprising the air inlet channel. The aircraft engine air inlet channel comprises an air inlet channel lip, an air inlet channel outer cylinder, an air inlet channel inner cylinder, an air inlet channel lip rotation driving motor, a driving gear and an arc-shaped gear strip. Wherein the air inlet channel lip is connected with the air inlet channel outer cylinder and the air inlet channel inner cylinder, the air inlet channel lip rotation driving motor is installed between the air inlet channel outer cylinder and the air inlet channel inner cylinder and connected to the driving gear, and the arc-shaped gear rack is installed in the air inlet channel lip and meshed with the driving gear. The air inlet channel lip rotation driving motor drives the driving gear to rotate, the arc-shaped gear strip is driven to rotate, then the air inlet channel lip is driven to rotate, and the air inlet channel outer cylinder and the air inlet channel inner cylinder cannot rotate. According to the technical scheme, the air inlet duct lip has the following beneficial technical effects that local rotation of the air inlet duct lip can be achieved, and the problem of top airflow separation of an air inlet duct of a crosswind lower back crosswind engine is solved.
