Hanwha Aerospace Develops 10,000-Pound-Class Turbofan Engine

Hanwha Aerospace has partnered with the Agency for Defense Development to create South Korea's first 10,000-pound-class turbofan engine. This ambitious project aims to boost the nation's independent aviation engine technology, nearly doubling the thrust from the current 5,500-pound class engines. The venture, valued at 177.3 billion won ($130 million), is set to run until October 2031.

The core of this ambitious initiative is to design a high-bypass ratio turbofan engine, primarily for use in low-observable reconnaissance unmanned aerial vehicles. This advanced engine technology, which allows more air to bypass the combustion chamber, improves overall propulsion efficiency and reduces fuel consumption. Moreover, the engine is designed to have an exceptional turbine inlet temperature, contributing to better thermal efficiency and engine output.

Hanwha Aerospace will manage the entire development process, from conceptual design to manufacturing completed engines and conducting rigorous test evaluations. The company's extensive 47-year experience in aviation engine development will be leveraged to lay the groundwork for the independence of domestic engine technology, encompassing design, manufacturing, and testing.

Key to the engine's design is the core technology of the existing 5,500-pound class turbofan engine. The development of this engine will focus on enhancing thrust to 10,000 pounds or more, improving high-temperature heat resistance, and ensuring a long lifespan. Additionally, the project aims to secure derivative engine development capabilities, enabling the expansion of existing engine technologies into various thrust classes.

The project also prioritizes weight reduction, as a lighter engine can increase an aircraft's cruising range, decrease fuel consumption, and allow for the mounting of additional weapons and equipment. Hanwha Aerospace's prior experience in aviation engine development, including the successful 5,500-pound class and 1,400-horsepower class turboprop engines, will be instrumental in this endeavor.

Securing independent engine technology is crucial as it can significantly impact the export competitiveness of the Korean defense industry. With military aviation engines being a strategic technology directly tied to national security, it's essential for major technology-possessing nations to maintain control over such capabilities. By developing an independent engine, Korea can avoid potential export constraints and bolster its defense industry's global competitiveness.
