Computational Fluid Dynamics

High-Fidelity Computational Fluid Dynamics (CFD) Analysis for Aerospace Applications

When precision matters, CFD becomes a mission-critical tool. At Fabexco, we use advanced Euler and Navier-Stokes solvers to simulate complex external aerodynamic and thermal phenomena with high fidelity – generating trusted aerodynamic databases that drive design refinement, performance optimization, and certification readiness.

From subsonic cruise to hypersonic reentry, our CFD services deliver detailed insights that far exceed what can be achieved with preliminary or linear methods. We help aerospace developers understand real-world flow behavior across every regime and configuration – with outputs ready for use in sizing, flight dynamics, propulsion, and structural workflows.

Our capabilities include:

• External Aerodynamics: Accurate prediction of lift, drag, pitching moments, and control effectiveness across angle of attack, sideslip, and Mach number ranges
• Complex Flow Phenomena: Simulation of shock waves, boundary layer separation, wake structures, and vortex dynamics
• Stability and Control Derivatives: Deriving high-fidelity aero databases for flight dynamics and control system development
• Unsteady and Transient Flow Modeling: Capturing time-dependent effects, such as dynamic stall, gust encounters, and rotor-wake interactions
• Hypersonic Flow & Shock-Dominated Regimes: Modeling dissociation, high-enthalpy effects, shock-boundary layer interactions, and coupled radiative heat transfer
• Aero-Thermodynamics: Simulating aerodynamic heating and thermal protection system (TPS) loads for high-speed vehicles and reentry conditions
• Propulsion Aerodynamics: Inlet distortion, nozzle flow, and integrated propulsion-airframe interactions – both powered and unpowered configurations
• Icing and Environmental Effects: Predicting ice accretion, airflow disruption, and performance degradation under supercooled droplet exposure
• Internal Flow Simulation: Analysis of flow within ducts, cooling passages, intakes, and exhaust systems for propulsion and thermal management
• Multidisciplinary Coupling: Integration with structural and thermal simulations for aeroelastic, aero-thermal, and propulsion-coupled studies

Applications

Our CFD analyses support critical phases of aerospace design and evaluation:

• Performance Optimization: Improving aerodynamic efficiency to enhance range, endurance, and fuel economy
• Stability and Control Databases: Quantifying stability derivatives and control response data to refine flight handling qualities
• Trajectory and Flight Dynamics Inputs: Developing aerodynamic models for trajectory prediction and flight envelope determination
• Aero-Thermal Assessments: Identifying and mitigating thermal risks during high-speed operations and atmospheric re-entry
• Advanced Aerospace Systems: Supporting the development of cutting-edge systems, such as low-observable configurations, morphing airframes, and emerging propulsion systems

Typical deliverables include:

• Aerodynamic Databases: Lift, drag, moment, and stability derivatives across trimmed and untrimmed conditions
• Flow Visualizations: Streamlines, Mach contours, pressure fields, shock locations, and wake structures
• Thermal Maps: Convective heat flux and surface temperature distributions for aero-thermal analysis
• Icing Reports: Ice accretion geometry and its impact on aerodynamic coefficients to support hazard analysis
• Powered CFD Analysis: Fully powered aerodynamics analysis, thrust/power effects, and loss-source quantifications
• Comprehensive Documentation: Methodology, boundary conditions, solver settings, mesh independence checks, and trade studies — all tailored to your project’s scope and fidelity requirements

Whether you’re refining a cruise-efficient wing, validating a high-Mach configuration, or solving complex flow challenges on an advanced airframe, Fabexco delivers the aerodynamic insight you need — with the accuracy and speed to keep your program moving forward.
