Fuel nozzle tip for CFM LEAP engines - redesigned as single 3D-printed cobalt-chrome part with integrated complex internal geometry.
Aerospace85% confidence
Challenge
Traditional fuel nozzle required 20 welded parts with complex internal cooling channels. Manufacturing was labor-intensive and prone to quality issues.
Solution
Redesigned as single 3D-printed cobalt-chrome part using electron beam melting (EBM). Consolidated 20 parts into 1 with integrated complex internal geometry.
Outcomes
- 0125% weight reduction
- 0230% cost savings
- 035x more durable than welded design
