Honeycomb seals

Bosman specialises in manufacturing and repairing honeycomb seals and segments. Honeycomb seals are used to optimise the turbine clearance between the rotating and stationary parts of aircraft engines. A clearance of 0.25mm increases fuel consumption by 1%.

As aircraft engines have to deal with variable pressure (taking off, cruising and landing), clearance management is an enormous challenge. As world leader in the field of active clearance systems, static clearance systems like honeycomb seals and segments are a perfect match.

Bosman manages all critical processes like:
• Vacuum soldering
• Matching with rotating knife edge seals (repair)
