Lightweight & Composite Structures


We provide cost-effectively optimised design & analysis solutions for primary & secondary composite and metallic structures.  Our experience covers a wide range of aero-structural parts:

  • CFRP wing and fuselage structures

  • High-lift device (flaps) certification analysis and documentation

  • Helicopter CFRP Nomex sandwich structures of fuselage, empennage

  • Spacecraft– Sandwich structures payload module

  • Engine– Nacelle and reverse thrust structures

  • Business jet CFRP structures, empennage, VTP and HTP

  • All composite light aircraft trainer

  • Fuel tank (Metallic Stiffened panel) pressure tests & certification stress report.

  • Aircraft interior stress analysis and report (seats and galleys)


Design and Analysis Capability

From involvement and experience in previous projects in the design and analysis of aero-structures with metallic and composite constructions, we provide technical consultancy services for the following topics:

  • Concept and configuration Analysis

  • Static/Fatigue Analysis, Check Stress and Certification documentation

  • Stiffened Panel Structures

  • Honeycomb / Foam Sandwich Panel Structures

  • Fatigue & Damage Tolerance

  • Bolted and Bonded Joints Analysis

  • Thermal Analysis

  • Buckling Analysis

  • Vibration & Modal Analysis

  • Non-Linear Analysis

  • Testing – Procedures and Support


Our analysis and simulation services are supported by our ability to specify qualification and material testing for component validation. 

We use the following design and analysis tools:


CAD: Catia V5 and Solid Works.  FEM: MSC Nastran/Patran for static & linear problems, Abaqus for non-linear issues such as material studies, large deformation analysis, contact and impact simulations.


Structural Optimisation: Aero Optimal Optimisation software tool

Manual calculations remain an essential part of our analysis services.
