FIELD: machine building.
SUBSTANCE: fastening assembly to fix ring sections on the casing of an aircraft gas-turbine engine comprises two strap clamps coupled in their back ends by a joint section which is protruded in the circular direction between the strap clamps. The front ends of the strap clamps are designed for pressing a ring section to a casing element to get them in contact. Fastening assembly on each side of the central plane being orthogonal to the circular direction comprises cutouts to grip the fastening assembly. Each cutout is made in the joint section and is made along the directional line parallel to the direction between the strap clamps. One more invention of the group relates to the device to fix ring sections, the latter comprises casing elements with the first back circular protrusions adjoined by the second back circular protrusions of the ring sections as well as a great number of fastening assemblies keeping the first and the second protrusions pressed to each other. Other inventions of the group relate to the turbine of gas-turbine engine and a gas-turbine engine which comprise the fastening assembly or the device to fix ring sections.
EFFECT: inventions allow for simplified maintenance of fastening assembly.
