Blade damage accounts for a substantial part of all failure events occurring at gas-turbine-engine power plants. Current operation and maintenance (O&M) practices typically use preventive maintenance approaches with fixed intervals, which involve hig

Numerical modeling approaches have been developed for simulating shot peening processes and consideration of compressive residual stresses when performing strength calculations of turbine wheel joints. A three-stage method is presented to combine str

The high-pressure turbine blades of most modern gas turbine engines are made of single-crystal alloys. Single-crystal materials have significant anisotropy characteristics; therefore, the orientation of the axes of the single crystal relative to the

Prevention of high cycle fatigue failures of blades caused by increased level of vibrational stresses is important problem in engine design and development. Different types of dampers are usually installed under the blade platforms in the region betw

Part 1 of this work discusses the numerical results of the performance efficiency investigation conducted for twin-web (hollow) discs in terms of stress and mass reductions. Three typical turbine discs and one small-sized turbine blisk are analysed u

The first part of this paper shows that the implementation of twin-web (hollow) discs can lead to an 8–30% decrease in mass or to a cyclic life increase of up to 300%, depending on the size of the disc and the operating conditions. The second part

The difficulty of providing the required strength characteristics of wheel locking joints is due to a complex stress state, the presence of stress concentrators, differences in contacting-part materials’ characteristics, and possible deviations in

The paper discusses prospects of using blisks with shrouded blades. Increasing an engine life and efficiency as well as mass reduction can also be achieved by increasing blade numbers and decreasing disk diameter. But design engineers are faced with
