GAS TURBINE WITH COMBUSTION CHAMBER FIXED TO NOZZLE BLOCK Russian patent published in 2009 - IPC F01D9/02 F23R3/60 

FIELD: engines and pumps.

SUBSTANCE: gas turbine comprises nozzle block of high pressure turbine with fixed blades distributed along axis, matching axis of combustion chamber, internal and external metal shells, and also internal and external flexible connection parts. Nozzle block is mechanically connected to back end portion of combustion chamber and creates a single unit with it. Unit created by combustion chamber and nozzle block is installed between internal and external metal shells. Internal and external flexible connection parts connect unit formed by combustion chamber and nozzle block of turbine, with internal and external metal shells for maintenance of specified unit between shells. Gas turbine additionally comprises facilities of turbine nozzle block rotation blocking relative to at least one of metal shells to avoid transfer of forces acting at blades of nozzle block of turbine by gas flow coming from combustion chamber, to parts of connecting components installed between unit formed by combustion chamber and nozzle block of turbine, and metal shells.

EFFECT: invention makes it possible to use connection parts that are not designed to withstand rotary and shifting forces.
