GAS TURBINE ENGINE BLOWER ROTOR, GAS TURBINE ENGINE WITH SUCH ROTOR AND ROTOR BLADE ROOT RING

摘要

FIELD: engines and pumps.;SUBSTANCE: blower rotor comprises disc furnished with blades with roots fitted in slots arranged along disc edges and rings, each being fitted between disc slot bottom and blade root. Front end of every end thrusts against retaining flange attached to disc and comprises ledge extending radially outward to retain blade root front end. Ledge of every ring comprises thrust rear surface for blade root front end to thrust against at overload. Note here that said thrust rear surface is inclined relative to rotational axis of rotor. Other invention of this set relate to gas turbine engine with above described blower rotor and to blade root ring.;EFFECT: decreased weight of gas turbine engine blower rotor.;15 cl, 3 dwg
