UNIT OF STATOR OF GAS-TURBINE MOTOR AND PROCEDURE FOR REPAIR OF THIS UNIT; ALSO MOTOR COMPRISING THIS UNIT OF STATOR Russian patent published in 2010 - IPC F01D9/00 F01D5/14 

FIELD: mining.

SUBSTANCE: unit of stator of gas-turbine engine consists of circular support elements and of multitude radial links distributed along circumference; said links are arranged between circular support elements to transfer structure effecting forces. Each radial link comprises a power core, a shockproof shell and power absorbing material. The power core is rigidly tied with two support elements forming a single frame together with the said support elements. The shock-proof shell envelops the core and is designed to endure a shock of one, less, power without damage, while power absorbing material is positioned between the core and the shell and is designed to absorb greater part of the shock power in case of shell damage with a shock of the other, greater, power. Other inventions of the group refer to gas-turbine and aircraft engines each including the above mentioned unit of the stator. One more invention of the group refers to the procedure for repair of the stator unit of the gas-turbine motor of the above described design, according to which after stator unit operation the worked out shock-proof shell and worked out power absorbing material are removed from each core, comprised into a single frame. After removal a new shock-proof shell and new power absorbing material are applied on these cores.

EFFECT: increased reliability of stator unit of gas-turbine motor and simple repair of such unit.
