REINFORCEMENT ELEMENT OF THE INTERNAL COATING OF THE UNIT OF THE EXHAUST SYSTEM Russian patent published in 2022 - IPC F02C7/20 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering for gas turbine technologies. Element for reinforcing the inner lining of the exhaust system unit, containing the outer lining, inner lining and thermal insulation between them, while the linings are connected by studs having welded seams with the outer lining, at least one clamping channel or clamping corner, and pin fasteners on the inner lining. The clamping channel is located at the junction between the two inner skins. The clamping angle is located at the junction between the two inner skins. Thermal insulation is installed between the outer and inner skins. The thickness of the thermal insulation is made from the condition: δ_out=(0.05÷0.15) V, where δ_out is the thickness of the thermal insulation; B is the internal width of the block. Clamping channels contain a linear section and two bends. Clamping corners contain a linear section and a bend. The stud connection has an internal nut. The stud fastener may have a support washer. The stud fastener has a pressure washer. The stud fastener has a clamping nut.

EFFECT: invention provides temperature compensations and reduction of heat transfer between skins.
