Aircraft Modification
Modelling and analysis
Stirling Dynamics can provide fluid dynamics modelling and analysis for retrofitted modifications to aircraft (including fuselage modifications), ranging from cameras, belly plinths and nose extensions through to blister fairings, radomes, sensor turrets and ISR system equipment.
With our efficient modelling methodology, we can provide a highly focused evaluation of platform performance, stability and control and aero loads data for design and certification purposes.
We can also offer wind tunnel comparisons, trade studies and design optimisation studies for external surfaces and attachments.
Electronic Decoy Design
Design, analysis and optimisation of fast-jet Expendable Active Decoy (external body)
We are capable and experienced in:
- Steady-state subsonic and supersonic modelling used to develop and down-select concept designs (including potential control surfaces)
- Dynamic fluid-body interaction (DFBI or FSI) modelling on mature geometries for in-depth performance analysis at range of Mach, altitudes, ejection angles
- Additional DFBI modelling of customer trials to recreate test conditions on final designs
In-House High Performance Computing (HPC) Technology
help with reverse engineering, validation of aircraft models and assessment of aerodynamic performance
Stirling Dynamics utilises in-house HPC resources, providing highly secure, readily available computing capacity. Our CFD offering complements our existing simulation and modelling capabilities. Our toolset industry experience includes main commercial solvers such as ANSYS Fluent & CFX as well as Siemens Star CCM+.
Hull Modification Analysis
TRUSTED PERFORMANCE PREDICTIONS FOR BETTER DESIGN DECISIONS
Our CFD capability can be used to analyse the impact of hull modifications to surface and submerged platform hydrodynamic performance, as well as assessment of design changes and configuration updates.
Towed Array Modelling
MODELLING COMPLEX MULTI-BODY SYSTEMS
Stirling Dynamics has a long history of modelling dynamic systems in the marine domain, including a diverse range of surface platforms, sub-surface platforms and cable towed vehicles/devices. Our CFD capability has been used to complement this offering by predicting hydrodynamic performance inputs to dynamic modelling as well as analysing more complex off-design / transitionary operating conditions.

Advanced Modelling Environments
FROM INDUSTRY-STANDARD CAE TOOLS TO BESPOKE MODELS
We can implement our models using a range of modelling environments from industry-standard CAE tools to bespoke models in MATLAB/Simulink, to standalone real-time software models for hardware-in-the-loop (HIL) testing and training simulations.
