Lightweight & Composite Structures

Aero-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.
