​Frame structures

Overview

GKN Aerospace has developed unique capabilities for the design, development, fabrication and assembly of lightweight engine frame structures in partnership with all the major OEMs. Fan/compressor, combustor and turbine structures are produced using our large multi-axis machining technology and specialised procesess such as automated large electron beam welding and electro-chemical machining.  

New design and development concepts use optimised combinations of complex castings, forgings and sheet metals in one or more materials. Welding and heat treatment process modelling along with advanced process control and automation makes this a robust and competitive route to large structural components.
 

Advantages

  • GKN Aerospace’s application of its own design practice and lean manufacturing principles to these complex assemblies has demonstrated our abiility to provide the highest quality product while achieving aggressive targets set by our customers.
  • Weight reducing technologies significantly contribute to the reduction of engine emissions.
  • Our experience in dealing with specialist supply chains and managing these products reduces risk for our customers.
