Airbus A350XWB-900 Fixed Trailing Edge

The most significant programme that Cascade Aerospace Engineering has been involved with, is the development programme for the Airbus A350XWB-900.

For this programme we supported a major risk sharing partner (RSP) develop the Fixed Trailing Edge for Airbus.  We provided a structural analysis integration solution, where we were regularly embedded within our clients engineering team and provided structural analysis decision making capability.  This included:

  • Provision of lead engineers, approvers and onsite integration at Airbus.
  • Co-ordination of the RSP supply chain from a technical perspective.
  • Integration effort with interfacing RSPs as necessary.
  • RSP Representative at many RSP/Airbus meetings.
  • Assessment of sizing data provided through the RSP supply chain.
  • Preparation, Support and presentation of PDR & CDR data.
  • Approval of B-Scheme, C-Scheme/C-Maturity & DFM data.
  • Assessment and development of structural design solutions for issues arising.
  • Assessment of all PRA issues to develop philosophy through negotiation with the end customer and analysis as required to prove integrity.
  • Compilation, checking and approval of reports, presentations and stress dossiers.
  • Development of loads and stress Finite Element Models to show load paths (IFEM) and investigate in more detail (DFEM) areas of concern.
  • Validation and verification of all models to ensure understanding.
  • Analysis of sheet metal & integrally machined components.
  • Analysis of composite structures.
  • Traditional hand calculations as required to prove all primary components.
  • Integration of major third party components.
  • Designing out fatigue and damage tolerance issues early in the task.
  • V&V activities across the FTE structure as necessary to ensure compliance.
  • Definition of and support to Structural Testing.
  • Report writing to end customer standard.
