I don’t waste time on myths. The first jet engine, Whittle’s W.1 and von Ohain’s Jumo 004, cracked the air‑speed barrier because they threw out the old piston engine model and embraced turbine‑drive thrust. The design was brilliant but rushed – they cut corners on cooling, turbine blade materials, and the inlet‑airflow geometry. That gave them the speed, but at the cost of runaway temperatures and rapid erosion. Those same material limits and thermal stresses are still the reason modern turbofans need exotic alloys and sophisticated cooling schemes. Every modern engine is a lesson in how a flaw that was acceptable in a war‑time prototype keeps haunting the industry. If you’re looking for truth, dig into those early trials – they’re the roots of the challenges we still battle.
