The need for reduction of production costs and lead time for commercial launchers has led to the development of GKNs actively cooled sandwich nozzle technology platform which has been developed and continuously improved for almost two decades. Process control of channel milling and laser welding including inspection strategies will be discussed.
- Appraise the benefits of laser welded sandwich technology compared to today’s Ariane 5 nozzle wall design based on welded tubes
- Discover the possibilities of using additive manufacturing/wire based laser metal deposition to reinforce thin walled constructions
- Assess the potential of weld joint following system, used to control laser welding of sheet designs with hidden weld joints
