The aerospace industry has experienced significant growth over the past decade and it is
estimated that nearly 30,000 new commercial passenger aircraft will be required by 2030 to …

Vibrating structures, such as gas turbine engines, are assemblages of multiple components
interfaced with each other through physical contact. The friction produced at these contact …

This paper presents the failure analysis of the turbine disc of an aero engine, installed in a
certain type of aircraft. From the visual examination of the fractured surface, it was possible …

A design optimization method based on kriging surrogate models is proposed and applied
to the shape optimization of an aeroengine turbine disc. The kriging surrogate model is built …

To make multi-objective reliability-based design optimization (MORBDO) more effective for
complex structure with multi-failure modes and multi-physics coupling, multiple response …

Turbine blade radial deformation seriously influences the Blade-Tip Radial Running
Clearance (BTRRC) of the high pressure turbine and the performance and reliability of gas …

Purpose–The purpose of this paper is to perform experiments on a full scale turbine blade
attached to a part of actual turbine disc at elevated temperature, which can accurately …

In this paper, we propose segmentation-aided digital image correlation (SA-DIC) for
measuring the deformation near the interface between two contact bodies. Conventional …

In this paper, based on the theory of elastic structure analysis, considering the rotational
softening and centrifugal stiffening of the blade, the dynamic model of the fir‐tree rotating …

Fir‐tree tenon structure, as a commonly used scheme in the connection of turbine blades
and discs, plays a critical role in the reliability and integrity of aeroengine turbines. This work …
