Whether it's the high-speed airflow generated by flight, or the high temperatures and pressures produced by the action of the combustion chamber, the goal is to increase the exhaust speed, allowing the turbine to operate at high intensity.
The key to an aviation engine's turbine is blade material, and turbine blades are one of the three major high-pressure components of an aviation engine.
Turbine blades can provide immense power, but the price is enduring temperatures far beyond their melting point, and tensile stresses of over ten thousand Newtons. Essentially, turbine blades must be able to withstand high temperatures and pressures, demanding high temperature resistance and strength.
"With the same design level for engine turbines and fans, for every 100 Kelvin increase in the temperature before the turbine, thrust increases by fifteen percent."
"This is where we're held back!"
