Life Assessment for Creep and Fatigue of Steam Turbine Blisk

International Journal of Advanced Engineering Research and Science, 2016
Steam Turbine Rotors are one of the key sectors among rotating machinery heavy engineering components. These machines operate at a constant speed at high pressure and high thermal gradients at the initial stages. One of the main factors concerning the mechanical integrity of these rotors is the interface between the blade and the disk.

Low Cycle Fatigue Life Estimation Of A Turbine Blisk

, 2017
This paper deals with low cycle life estimation of a turbine blisk. The turbine blisk operates at extreme conditions; hence it is subjected to aerodynamic loads and high centrifugal loads. The loads on the turbine blisk vary due to the mission profile of the vehicle that includes takeoff, cruise and landing.

Design of the blisk of an aircraft turbojet engine and verification of its resonance free operation

Applied and Computational Mechanics, 2016
Integral turbine wheels belong to one of the most stressed parts of jet aircraft engines. In addition to high rotational speeds and temperatures, they are also subjected to dynamic forces from a non-uniform pressure field in the flow path. Dynamic forces

The LOW CYCLE FATIGUE LIFE ESTIMATION OF A TURBINE BLISK

International Journal of Advance in Scientific Research and Engineering (IJASRE), 2017
This paper deals with low cycle life estimation of a turbine blisk. The turbine blisk operates at extreme conditions; hence it is subjected to aerodynamic loads and high centrifugal loads. The loads on the turbine blisk vary due to the mission profile of the vehicle that includes takeoff, cruise and landing. An elasticplastic finite element analysis is

Ensemble Learning Based Surrogate Modeling for Gas Turbine Blisk Temperature Predictions

Annual Conference of the PHM Society, 2018
Temperature prediction in complex systems like gas turbines provides insights to temperature dependent damage accumulation but usually involves a huge computational cost. For simulation-based prognostics, the computational cost is a major hindrance to a real time implementation.

Experimental studies of prototype models of bimetallic blisks of a high-temperature turbine with cooled blades for advanced gas turbine engines

VESTNIK of Samara University. Aerospace and Mechanical Engineering, 2015
The traditional approach to designing turbine blisks based on the application of disk-blade pawl-coupling does not allow improving the design from the point of view of increasing the service life, reducing the wheel mass and improving the engine efficiency on the whole.
