FIELD: engines and pumps.
SUBSTANCE: disclosed is structure in combination with jet engine blade connecting blade, intended for connection of blade to jet engine, wherein blade is made from composite material. Connecting support element 33, including pair of separated parts 34, 34, is located in connection part between proximal end section 21 of guide vane 20 and attachment flange 31f, and said pair of separated parts 34, 34 is connected with blade proximal end section 21 on both sides in direction of blade thickness. Slot 35b is formed in one coupling surface 35a with end section of said connecting support element 33, linear projection 35c is formed on the other coupling surface 35a with end section, wherein said blade proximal end section 21 is formed in concave-convex shape, wherein straight projection 21b, which engages with slot 35b, which is formed in coupling surface 35a with end section is formed on the coupling surface 21a with one coupling surface 35a with end section, slot 21c, which engages with the straight projection 35c, formed on coupling surface 35a with end section is formed in coupling surface 21a with other coupling surface 35a with end section. Blade proximal end section 21 is retained between pair of separated parts 34, 34 of connecting support element 33 by clamping force, which is applied to connecting support element 33 on both sides in direction of blade thickness.
EFFECT: possibility to obtain high structural strength, while providing reduced jet engine weight.
