How Are Increasing Temperature Requirements Pushing The Limits Of Engine Technologies?

The performance of jet engines is measured through the amount of thrust it produces per unit of fuel. In other words, a jet engine is typically advertised to the market for its fuel efficiency. The amount of thrust is directly proportional to the pressure ratio of the air entering the engine to the air exiting the engine. As a result of the manufacturers race to develop ultra-fuel-efficient engines, they must run hotter than ever to produce increasing levels of thrust.
