Efforts Underway to Localize Key Aircraft Engine Materials, Reduce Reliance on Overseas Suppliers
Korea Aerospace Administration ramps up development of high-strength, heat-resistant materials and components
Developing aluminum and superalloys, while securing certification technologies
Efforts are underway to localize key materials and components that determine the safety and performance of aircraft engines. The goal is to reduce reliance on overseas suppliers by developing domestically the materials used in engine structures that can withstand high-temperature, high-pressure environments.
The Korea Aerospace Administration held the “Symposium on the Development of High-Strength Materials and Components for Aircraft Engine Structures” at the Daejeon Convention Center on October 29. Around 100 people, including representatives from companies, universities and research institutes, attended to discuss the status of technology development and plans for addressing certification requirements.
The Korea Aerospace Administration has been pursuing the “Development of High-Strength Materials and Components for Aircraft Gas Turbine Engine Structures” project since this year. The materials and components being developed include aluminum castings and forgings for lightweight frames, stainless steel materials for housings, and nickel-based superalloys for combustor modules.
Aircraft engine materials must maintain their performance under high temperatures and pressures and repeated loads. To be used in actual engines, they require not only materials development but also stable manufacturing processes, reliable material property data, testing and evaluation, and certification.

“It is important to build up the necessary capabilities step by step in Korea, from materials development to manufacturing processes, testing and evaluation, and certification,” said Tae seog Oh, administrator of the Korea Aerospace Administration. “We will provide support to ensure that development outcomes lead to actual use in aircraft engines and enable domestic companies to participate in the supply chain.”
