Why Aircraft Engines Are So Difficult to Manufacture?
A modern jet engine operates under extreme conditions:
🔥 Temperature above 1,000°C
💨 Air speeds above Mach 1
⚙️ Tens of thousands of rotating parts
🛠 Decades of certification requirements
Developing a new aircraft engine can require:
- 8–10 years of development
- Billions of dollars investment
- Strict aviation certification
Key Insights
1. Four Companies Control Most of the Market
The commercial aircraft engine industry is essentially dominated by:
- GE Aerospace
- CFM International
- Pratt & Whitney
