Aerodynamics — CFD services
Aerodynamics is the science of how objects move through air. Accurate prediction of lift, drag, stability, and turbulent flow helps create safer, more efficient aircraft and vehicles.
Analysis approach and scope
RANS and DES methods can be used across the regimes described below. Accuracy depends on the geometry, mesh, boundary conditions, turbulence model, and available validation data; the appropriate method and limits are agreed for each case.
Typical outputs
- Aerodynamic coefficients and load distributions for agreed conditions
- Static or dynamic stability results and flow-field evidence
- A documented comparison against available wind-tunnel, flight, or reference data
