Why Jet Engines Aren't "Made in China"
China lags in jet engine manufacturing due to extreme technical challenges in materials science, precision engineering, and a lack of decades of accumulated Western craftsmanship, despite its broader industrial rise.
Background
- Jet engines are among the hardest machines to build, requiring superalloys that withstand near-melting-point temperatures, single-crystal turbine blades with intricate internal cooling, and decades of iterative testing. Only a few Western firms (GE, Pratt & Whitney, Rolls-Royce, Safran) have mastered this.
- China has poured state resources into catching up via projects like the CJ-1000A (for airliners) and WS-10/WS-15 (for fighters), but repeatedly struggles with blade fatigue, material defects, and certification.
- The article argues that while China can manufacture most parts, achieving the reliability and safety certification (FAA/EASA) of incumbents may take another decade. This matters because jet engines are a bottleneck for China's aviation ambitions (C919 airliner) and military power.
