Turbine Blade Shape and Principle

Turbine blades are core components in aircraft engines, gas turbines, and some high-performance automotive supercharging systems. Their unique shape and design ensure high aerodynamic efficiency.

Blades typically have a curved, three-dimensional, twisted shape, similar in cross-section to an airfoil, with a rounded leading edge and a tapered trailing edge, effectively guiding high-speed airflow.

The blades operate by using the high-speed flow of gas to impact the blades, causing them to rotate and drive the rotor, thereby converting thermal energy into mechanical energy.

Turbine blades are typically made of nickel- or cobalt-based high-temperature alloys to withstand the extreme temperatures and mechanical stresses of high-speed rotation.
