Abstract:

In article a design of a combined protective device of a two-circuit turbojet engine, including a system of protective grilles of different sizes and a reflector in the form of movable blades is proposed. The protective device is designed to prevent various foreign objects from entering the engine, as well as birds. The method of calculation of protective gratings is given. The proposed combined protective device provides an increase in the reliability and safety of turbojet engines.
