Why Jet Engines Aren't "Made in China"

- China's jet engine program highlights the limitations of its industrial policy, as it has struggled for decades to match Western technology despite heavy investment.
- Jet engine manufacturing involves extreme technical challenges, such as creating turbine blades that withstand hotter-than-lava temperatures and require single-crystal casting with low yield rates, relying on a global supply chain.
- The industry features slow iteration cycles, stringent certification processes (like FAA/EASA), and low profit margins, which neutralize China's usual advantages in scaling and speed.
- China excels in industries with fast iteration, legible targets, and underserved demand (e.g., EVs, batteries), but jet engines lack these attributes, requiring accumulated knowledge and long-term reliability focus.
- Military engine programs have seen some success, but China remains behind Western counterparts by about two decades, with commercial engines like the CJ-1000A facing delays and limited market prospects.
- Reverse engineering and capital investment alone cannot replicate the tacit knowledge and specialized supplier networks that underpin Western jet engine dominance.
- The economic case for China's commercial jet engines is weak, with high costs and limited domestic sales, while opportunity costs are high given other strategic areas like AI and semiconductors.
- Western innovation thrives on decentralized, risk-taking capital in areas like supersonic jets and autonomous drones, contrasting with China's state-directed focus on scaling established technologies.
