Structural Analysis & Simulation

Stress Analysis: Aero Optimal Ltd was involved in the concept configuration, optimisation & weight saving work packages of the forward & aft fuselage composite structures of the A350XWB shells.


Our internal R&D programs have developed software tools for curved stiffened panel structures (skin/stringer and frame structures).

We use industry-standard linear and non-linear Finite Element Analysis and also offer compilation checking & approval of composite & metallic static/fatigue stress dossiers & supporting data.

Design: In support of the A350XWB metallic & composite engineering, we have provided the associated Catia 2D drawing sets with BOMs & 3D models inclusive of FibreSim content. Compilation of detailed weights/inertia / CG reports per assembly for inclusion in the aircraft weights model.

Manufacturing-Support: From our experience in the development & support of A350XWB composite/metallic quality control programs, we help prove consistent manufacturing processes (Witness Specimen Program), First Article Inspections, First Part Qualification, Drawing Query Notes, Drawing Change Notes, Concessions & Generic repairs.


Structural Repair Manuals:

We provide analysis & compilation of the structural repair manual entries applicable to the primary & secondary structures.

Liaison: Our extensive experience attending multiple international program reviews will enable us to recommend improvements to the evolving design & manufacturing process whilst offering proposals & solutions to technical issues.

Structural Testing: Completing structural / certification test proposals, test rig design, forecasting strain/deflection results, FEM models & compilation of results dossiers.

Training: Based on our extensive experience and involvement with the A350XWB technical review board at the central entity, we provide advanced, adaptable technical coaching in the design analysis and optimisation of  composite structures.

Pedigree: The following are programs that our engineers have participated in:
Military: NH90, SD330-340
Civil: A350XWB-900 – 1000, A380, A340, Avanti P.180, MD11, Eurotrainer, AS907/HTF7000
Space / Other: SOHO spacecraft / Horizontal Composite Wind Turbine Blade
