FIELD: machine building.SUBSTANCE: radial ring flange on its outer or inner periphery comprises alternating projections with holes for fastening tightening bolts and hollows as well as tools to prevent faulty angle joint by preventing bolts from entering a hollow. The tools to prevent faulty angle joint are formed by the bottom of at least one hollow of the inner or, respectively, outer periphery with its radius in relation to the turbomachine axis being less or, respectively, greater than the radius of the circle externally or, respectively, internally tangent to the holes for the bolts to pass through the projections. The other invention of the group relates to the connection of gas-turbine engine elements comprising the above said flange fixed by the bolts with ring clamps. The bolts are placed between the clamps' holes and in the flange projections' holes; the bottom of smaller or, respectively, greater radius is placed between the two flange projections and two projections of at least one of the clamps. One more invention of the group refers to a gas-turbine engine comprising the above connection.EFFECT: invention eliminates risk of faulty ring flange installation.8 cl, 6 dwg |
