Abstract

The invention relates to a sealing device for an aircraft engine propeller, for use during the water landing of an aircraft. The device operates in a space between the propeller and the fuselage of the engine and comprises an O-ring coupled to an activating mechanism, the O-ring and the activating mechanism being arranged coaxially to the rotor of the engine. The activating mechanism moves the O-ring from a retracted position, in an opening in the fuselage of the engine, to an extended position, against a plate of the propeller cone, hermetically closing the space between the propeller and the fuselage of the engine, preventing water from entering the engine bay, and stopping the engine in order to protect the propeller from the impact against the water during the water landing of the aircraft.
