Jet Engines - The Most Delicate Component

In a jet engine, you are injesting air from the front, pulling it in and sucking it in. You are mixing that air with fuel at extremely high temperatures. That is a very high temperature and high pressure reaction which tends to destroy the turbine blades of a jet engine. So if you have a regular turbine blade made out of your typical steel, or whatever metal you use, it's going to degrade very rapidly. And because of that, what the jet engine manufactures have to do is that they have to develop exotic materials. They construct this turbine blades as a single crystal of metal. The entire blade is grown like you grow a plant or a tree. It's grown and it's
