Doosan Enerbility Collaborates with Agency for Defense Development to Manufacture Core Components of Aviation Gas Turbines

Blades and Vanes for Aero Gas Turbine Engines
'Engine Layout Design and Analysis Service Contract' Diversifying Gas Turbine Business

Doosan Enerbility, which succeeded in developing the fifth gas turbine for power generation in the world, has diversified its business by participating in the production of core components for aircraft gas turbine engines.

Doosan Enerbility announced on the 21st that it signed a contract with the Agency for Defense Development for the task of ‘casting and post-processing of turbine vane and blade products.’ Doosan Enerbility plans to manufacture blades and vanes, which are core high-temperature components of the aircraft gas turbine being developed by the Agency for Defense Development, and supply them to the agency by 2027.

The rotating blades connected to the gas turbine rotor are called blades, and the fixed blades between the blades are called vanes. The vanes serve to gather the airflow scattered after passing through the blades.

This contract is part of the Agency for Defense Development’s project ‘Development of Turbo Fan Engine Element Technology for Unmanned Aerial Vehicles.’ In June, Doosan Enerbility signed a contract with the Agency for Defense Development for layout design and component analysis services of the aircraft turbofan engine.

Aircraft gas turbine engines are divided into turbojet, turbofan, turboshaft, and turboprop engines. Most aircraft adopt the turbofan engine method. The turbofan engine has one fan that intakes air and two airflow paths. One airflow passes through the engine core (combustion chamber), and the other airflow (bypass air) flows outside the core.

Aircraft and power generation gas turbines operate on the same technology base and have similar operating principles and structures. Aircraft gas turbines primarily focus on securing thrust (the force that pushes an object in the direction of motion), with design priorities on high output, lightweight, and operational flexibility. Power generation gas turbines aim for high efficiency, high output, and stability, and differ in being larger compared to aircraft gas turbines.

Park Hong-wook, Head of Power Service BG at Doosan Enerbility, said, “Winning this project is significant in that Doosan Enerbility has expanded its business area to aircraft engines based on the design and manufacturing technology of power generation gas turbines developed in cooperation with domestic industry, academia, and research institutes. We will also focus on developing aircraft gas turbines based on the technology and systems accumulated during the power generation gas turbine development process.”
