Creep and long?term strength of micro?GTU turbine disk
Keywords:
gas?turbine unit; creep; long?term strength; strain accumulation.Abstract
Creep and long?term strength limits durability of micro gas turbine unit, designed as an auxiliary source of electrical energy. The papers shows that usage of usual creep reference data only does not allow to describe stress redistribution and long?term fracture, while usage of long?term strength data only does not allow to estimate accumulated displacements. A method, that takes into account both steady?state creep and tertiary creep, is offered.Downloads
