COMPOSITE PART OF MACHINE AND GAS TURBINE Russian patent published in 2013 - IPC F01D1/00 

FIELD: machine building.

SUBSTANCE: composite part of machine for a gas turbine with the main part made of an initial material, which in a partial area of its surface is equipped with lining from applied material with higher hardness and/or viscosity compared to the initial material. The lining is formed by certain number of lining elements, which in their longitudinal direction are applied onto the main part with an inclination towards the main flow of hot gas passing via the main part, so that lining elements cover the main body in a spiral manner. The gas turbine is made with a certain number of composite parts of the machine, namely, a fire tube, a combustion chamber, a mixing chamber of the combustion chamber and/or an inner body of the combustion chamber are arranged as composite parts of the machine.

EFFECT: invention makes it possible to increase transverse stability and torsional rigidity of rings that form the main part, and especially preferable direction of cooling air with simultaneous flexibility of the main part during further treatment.
