FIELD: engines and pumps.SUBSTANCE: gas turbine blower rotor comprises disc with blades arranged in disc slots and circular case shaped to truncated cone and fitted at disc by means of tappet lock at blade entrance. Said case comprises radial inner toothed flange with solid parts located to alternate with hollow parts and fitted in disc outer circular groove confined, on entrance side, by radial outer circular toothed flange. Case flange outer edges are connected with baffle to be deformed in blower blade loss or break-away. Hollow parts of said flange comprises radial recesses to facilitate resilience in flexure of its solid parts. Other inventions of the set relate to gas turbine engine and pilot engine with aforesaid blower rotor. One more invention of the set relates to blower rotor circular case.EFFECT: simplified design, decreased weight and overall dimensions.9 cl, 8 dwg |
