A Design Study in Nickel-Based Superalloy Castings-- Combustor Floatwall Panel

Manufacturing Challenges

  • Depending on the engine size and design, the number of panels in an engine combustor may range from 60 to 140 per engine set.
  • Hitchiner Manufacturing, Gas Turbine Division, produces approximately 100,000 panels per annum for more than 14 production engine configurations, both military and civilian.

The challenge in manufacturing these panels was to select the best combination of metal alloy and fabrication method that would meet the performance and production targets, specifically --

-- Achieving high temperature alloy performance.
-- Producing the cooling pins and attachment studs with the desired accuracy.
-- Meeting the required dimensional tolerances for fit and function.
