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 resulted in the development of many software tools applicable to curved stiffened panel structures (i.e. skin stringer frame structures).

We use industry standard linear and non-linear Finite Element analysis and can 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 BOM’s & 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 can provide support to 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 can provide analysis & compilation of the structural repair manual entries applicable to the primary & secondary structures to the standards demanded of EASA.

Liaison: Our extensive experience in 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: Completion of structural / certification test proposals, test rig design, forecasting of 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 can provide advanced adaptable technical coaching in the design analysis and optimisation of large ‘CAT- A’ composite structures.

Personnel: Our technical ability has allowed us to supply stress, design, and integration teams to Airbus Americas in support of European based efforts on the A350XWB primary structures.

Pedigree: The following are programs that Aero Optimal engineers have participated in.

Military: NH90, SD330-340
