Keywords: The article deals with design changes aimed at reducing or preventing damage caused by foreign bodies entering the air intakes of aircraft engines. A new design of the engine protection device is proposed, in which the first mesh is conical, due to which there will be an oblique impact and the force is partially transferred to the mesh, which reduces its load and the probability of failure. The method of determining the stresses acting in the grid wires is given. The mechanical characteristics of modern artificial materials are given.
