Why it’s so hard to build a jet engine by Brian Potter
It’s not that building a working commercial jet engine itself is so difficult. It’s that a new engine project is always pushing the boundaries of technological possibility, venturing into new domains — greater power, higher temperatures, higher pressures, new materials — where behaviors are less well understood. Building the understanding required to push jet engine capabilities forward takes time, effort, and expense.
