TURBINE MODULE FOR GAS TURBINE ENGINE Russian patent published in 2009 - IPC F01D25/24 F01D9/04 F01D11/08 

FIELD: engines and pumps.

SUBSTANCE: turbine module for gas turbine engine comprises at least one annular distributing device and turbine rotor. Said distributing device incorporates ring-sector-shape multiple elements. First part of said elements supports fixed vanes arranged radially towards turbine axis, while another part, together with turbine rotor vane ends, form sealing means. Every aforesaid ring-sector-shape element is fastened inside the case by radial hook attached to the latter or to said element to interact with a pair of axial hooks to aforesaid element or case, respectively. Elements' fasteners additionally comprise an axially oriented pin arranged between two sectors of the other distributing device located downstream of the ring flow for said pin to make locking device inhibiting rotation of ring-sector-shape elements. Each of the latter comprises also first radial thrust surface adjoining the case radial support. First radial thrust surface seta downstream of axial hook and upstream of the pin oriented axially.

EFFECT: simple assembly of turbine stages, simplified design.
