Turbine Centrifugal Compressor Impeller

A Turbine Centrifugal Compressor Impeller (often referred to as a compressor wheel or centrifugal impeller) is a rotating component within a turbocharger or centrifugal compressor system. It plays a dual role in forced induction systems:

1. Turbine Side: Driven by exhaust gases, it extracts energy from the engine’s exhaust flow to spin at high speeds.

2. Compressor Side: The impeller’s rotation draws in ambient air, accelerates it radially outward via centrifugal force, and compresses it before delivering it to the engine.
   Crafted from heat-resistant superalloys (e.g., Inconel) for the turbine side and lightweight alloys (e.g., aluminum, titanium) for the compressor side, the impeller’s aerodynamic blade geometry ensures efficient energy transfer and minimal turbulence. Its design prioritizes high rotational stability, thermal fatigue resistance, and pressure ratio optimization, critical for performance in automotive, aviation, and industrial turbo-machinery.
