FIELD: engines and pumps.

SUBSTANCE: fixing structure for attachment of a guide blade to a frame or a casing of a fan of an aircraft engine. The guide blade is formed of composite material. The guide blade is intended to straighten an air flow. The fan casing is arranged outside the fan frame. The fixing structure includes the following: a mating surface, the first installation section, a supporting element, a supporting mating surface and the second installation section. The mating surface is formed in an end section of the guide blade. The first installation section is formed in the mating surface of the guide blade. The supporting element is made from metal as its component material, with that, the supporting element is connected in the form of an integral unit of the fan frame or the fan casing. The supporting mating surface is subject to conjugation with the mating surface of the guide blade and formed in the supporting element. The second installation section has a possibility of wedge-like adhesion to the first installation section of the guide blade and formed in the supporting mating surface of the supporting element. Rigidity and strength of conjugation is increased between the guide blade and the frame or the casing of the fan.

EFFECT: improved design.
