FIELD: engines and pumps.
SUBSTANCE: connecting structure, which is part of jet engine and blade made from composite material of thermosetting resin or thermoplastic resin and reinforcing fibres, and connecting support element. Connecting supporting element includes a pair of separated parts, is located between near end part of blade guide vane and attachment flange, and pair of separated parts are connected to near end part of blade on both sides in direction of thickness of blade. Linear protrusion is formed on one of surfaces of joint of near end part of blade with a pair of separated parts. Groove, which is engaged with linear protrusion, formed in near end part of blade, is formed on one of corresponding surfaces of joint of pair of separated parts connecting supporting element. Near end part of blade is retained between a pair of separated parts of connection of supporting element by means of clamping force, which is applied to pair of separated parts of connection of supporting element on both sides in direction of thickness of blade.
EFFECT: higher structural strength with reduction of weight of jet engine.
