Project & Programme Management


Morson Projects were responsible during C-MAT and DFM for the analysis and design of metallic and composite parts for the mid and Outer Fixed Leading Edge, for the A350-1000.

Morson Projects were also responsible for the complete fixed leading edge residual strength analysis to support the A350-1000 First Flight, including UERF, Hail Strike and MLP.   Some of the items included within the design and analysis activities are as follows:

  • Flap Track Ribs
  • Intermediate Ribs
  • Hold Down Ribs
  • Closing Rib
  • Spreader Plates
  • Fixed System Brackets
  • FTI Provision
  • J-Nose composite Panels
  • Lower Removable Composite Panels
  • Buttstraps
  • De-Ice Region
  • System Raceway

In support of the design of the items above, Morson Projects were responsible for producing and using:

  • Complete programme management
  • Design Deliverables
  • Detailed Design using CATIA V5, R23 (CATIA format applicable to the A350 programme)
  • DFM Drawings
  • Frontier and Interface Drawings, PKCs etc.
  • Full Utilization of PDMLink
  • Mass Reporting (BOM)
  • Stress Deliverables
  • Stress Reports (C-Scheme & DFM)
  • Analysis using Excel, MathCAD, NASTRAN, PATRAN, ISAMI
  • Interface Loads Reports
  • Static Sizing Reports
  • Detailed Finite Element Models (DFEM)
  • Exceedance check reports ( Residual Strength)
  • FLE IFEM models for MLP, UERF and HailStrike (Residual Strength)
  • Fatigue and Damage Tolerance
