General Information
1.1
Project Information
Gas turbine engine structural integrity project, initiated in 2022, is a research and
development program led by the Korea Aerospace Research Institute (KARI) and
supported by the Government of Republic Korea to establish core technologies for
gas turbine engine structural integrity. Aircraft gas turbine engines operate under
extremely demanding conditions, including high temperature, high rotational speeds,
and complex loading environments. Ensuring the structural integrity of engine
components under such conditions is a critical factor for engine safety and
certification. Therefore, a systematic structural integrity framework that includes
structural analysis, life assessment, damage tolerance evaluation, and reliability-
based assessment method is required.
This project mainly addresses the establishment of a structural integrity framework
and analytical methodologies for gas turbine engines, and aims to develop a Master
Plan for gas turbine engine structural integrity to support these activities.

Introduction
2.1
Structural integrity of gas turbine engines
Aircraft gas turbine engines are complex mechanical systems operating under severe
environments characterized by high temperatures, high rotational speeds, and combined
thermal and mechanical loading. Under these conditions, engine components are exposed to
various damage mechanisms such as fatigue, creep, and vibration, which may affect their long-
term structural reliability.
The structural integrity of engine components is therefore a key consideration throughout the
engine development process. Components such as compressors, combustors, turbines must be
designed and evaluated to withstand demanding operating conditions while maintaining the
required safety margins.
In addition, aircraft propulsion systems are subject to strict structure integrity requirements.
International aviation authorities, including FAA and EASA, establish certification standards to
ensure the safety and reliability of aircraft engines. These standards require comprehensive
evaluation and verification of the structural integrity of critical engine components.
Figure 1. Structural integrity programs (FAA, EASA, MIL)
2.2
Master Plan for engine structural integrity
To effectively address structural integrity requirements during engine development, a
systematic and integrated approach is necessary. This approach should define the analytical
methodologies, evaluation procedures, and technical strategies required to assess structural
integrity throughout the engine lifecycle.
SOW of Advisory review of Master Plan (D)

For this purpose, a structural integrity Master Plan is required to provide a structured
framework for managing structural integrity considerations in engine development programs.
The Master Plan is intended to outline the methodologies and processes necessary to support
structural integrity evaluation and to guide future gas turbine engine development activities.
