SUBSTANCE: invention relates to the aircraft engines protection means against ingress of foreign objects. Proposed engine protection device against ingress of foreign objects comprises moving lower panel (1) installed by the air intake housing (3) fasteners (5) in two guides (2). Lower panel (1) is hinged to the rigidly fixed on the air intake housing (3) drive (4) rod. In lower panel (1) there are cutouts (6, 7) located at relative distances of 
with relative length of 
where λ is the lower panel length, m; a is distance from the lower panel leading edge to the first cutout, m; c is distance from the lower panel leading edge to the second cutout, m; d is the cutout length, m.
EFFECT: invention increases the engine against the ingress of foreign objects protection device efficiency in all operating modes on the ground.
