The invention discloses an aircraft engine protective device. The aircraft engine protective device is characterized by comprising three blades made of carbon fiber materials, every two adjacent blades form a 120-degree angle, a trundle is arranged at the tail end of each blade, the trundles are installed in a metal ring of a guide rail structure, and the metal ring is installed on a fairing of an aircraft engine. During operation, the aircraft engine produces great suction force, the suction force is acted on the three blades of the fairing, the three blades are similar to air blades of a wind driven generator, rotate at a high speed and form a dynamic air-tight protective cover for the fairing of the aircraft engine, flying birds approaching to the aircraft engine will be ejected out by the rotating blades and will not be sucked into the engine, and therefore the flight safety of an aircraft is protected.
