FIELD: engines and pumps.
SUBSTANCE: proposed base panel for worn-out coating for a jet turbine engine contains a stiff base to be attached to a fan casing inner wall, one side of which is covered with a laminated structure supporting the worn-out material layer. Laminated structure contains fibre layers submerged into polymer material, as well as the first part with worn-out coating applied to it and the second part located beyond the worn-out coating. Rear part thickness exceeds front part thickness and can resist ice strokes. The other invention of the group refers to a nacelle of a jet turbine engine, which includes base panels for worn-out coating, which are made as described above. One more invention of the group refers to an aircraft jet turbine engine containing base panels for worn-out coating, which are made as described above and located opposite fan blades. Rear parts of laminated structures of those panels are arranged behind fan blades before sound-insulating panels.
EFFECT: inventions allow simplifying fabrication and maintenance of panels with worn-out coating.
