Hot-section components are essential parts of high-end power equipment, primarily including combustion chambers, turbine blades, turbine vanes and turbine discs. These components operate in high-temperature, high-pressure and complex stress environments, and their performance directly affects the energy conversion efficiency, power output, reliability and service life of engines. Due to the high requirements for high-temperature materials, structural design, precision manufacturing and quality control, hot-section components are considered one of the most technically challenging and valuable segments of the engine manufacturing value chain. In recent years, continuous advancements in key technologies such as superalloys, thermal barrier coatings, advanced welding techniques and cooling technologies have enhanced the performance of hot-section components, driving aero-engines, gas turbines and rocket engines toward higher power output, higher operating temperatures, improved thermal efficiency and greater reliability.
The industry of aero-engine, gas turbine and rocket engine hot-section components has received long-term support from national policies. In the aero-engine sector, the “Aero-Engine and Gas Turbine” Major Special Project launched in 2016 focused on strengthening capabilities in core technologies, advanced materials, key components and industrial ecosystem development. The 15th Five-Year Plan issued in 2026 further emphasized the development of strategic emerging industries, including aerospace and high-end equipment manufacturing, while promoting technological innovation and supply chain resilience. In the gas turbine sector, the Catalogue for Guiding Industry Restructuring (2024 Edition) issued in 2023 identified critical components such as rotor forgings for heavy-duty gas turbines, large superalloy turbine discs and turbine blades as encouraged development areas. The Guiding Opinions on Energy Work for 2025 proposed strengthening the monitoring and management of pilot projects for the innovative development of gas turbines, while supporting the localization of the gas turbine supply chain and accelerating the engineering application of related technologies. In the rocket engine sector, continuing implementation of China’s space development strategy has supported growing demand for high-performance rocket engines and related hot-section components. With policy support, growing downstream demand and ongoing advances in manufacturing technologies, China’s aero-engine, gas turbine and rocket engine industries have maintained steady growth, creating favorable conditions for hot-section component manufacturers. In the future, continued domestic substitution, overseas market expansion and rapid technological advancement are expected to support further growth of the industry.
