FIELD: the invention refers to the field of aviation mechanical engineering and may be used at designing, manufacturing and exploitation of turbo-fan engines.
SUBSTANCE: the body of the fan of an aviation engine has a casing out of composite material, zones of fastening with mated units and aggregates. It is fulfilled solid along the depth and multi-layer in the thickness of alternating spiral layers of organic braid and packets of organic cloth on epoxy binder. At that in the zone of the location of the blades spiral layers and cloth packets are repeatedly alternate with each other, and the inner and the exterior layers are fulfilled spiral, the end face zones are reinforced with cloth packets which are fastened with ring layers and elements of the pin-bolt connection are located in them.
EFFECT: the invention allows provision of fulfillment of demands of international norms at providing reliability and safety of the flight of a plane at the expense of containment of a turned off blade or its fragment by a fan's body.
