LOW & HIGH-PRESSURE TURBINE ACTIVE CLEARANCE CONTROL COOLING SYSTEMS

Aero engine efficiency is becoming an increasingly important factor for the aviation industry for both operational costs as well as reducing greenhouse gas emissions. Active Clearance Control cooling systems ensure turbine efficiency and therefore emission reductions.

ACTIVE CLEARANCE CONTROL (ACC)

SA Bosman is the world market leader in the field of co-designing and manufacturing Active Clearance Control systems.

The ACC system ensures that the clearance between rotating and stationary parts of an aircraft engine is optimized. This is of great importance, as 0.25mm of clearance increases fuel consumption by around 1%. The system is called active, as the amount of compressor cooling air can be adjusted to alter cooling air temperature.

We combine years of manufacturing engineering knowledge and experience in ACC’s and sheet metal with complex Fluid Dynamics to develop cooling systems with the optimal heat transfer and cooling performance.
