We model.
We simulate.
We Trim.
High-fidelity engineering simulators for aircraft, airships, UAVs and unconventional vehicles — from aerodynamic modelling to real-time flight dynamics and control.
From physics to a simulator you can fly.
We build tailored simulation environments around your vehicle, your aerodynamic data and your engineering objectives.
Aerodynamic Modelling
CFD-informed aerodynamic databases, coefficient models, interpolation, force and moment reconstruction, and model validation.
Flight Dynamics
Nonlinear 6-DOF equations of motion, atmosphere, wind, propulsion, mass properties, actuators and vehicle-specific physics.
Control & Allocation
Control-law prototyping, PID and cascaded architectures, actuator allocation, trim analysis and closed-loop evaluation.
Real-Time Simulation
Interactive simulators with pilot inputs, real-time pacing, telemetry and 3D visualization for engineering and demonstration.
Model Validation
Simulation-to-flight comparison, parameter tuning, sensitivity studies and progressive model improvement using test data.
Integration & Testing
Engineering environments designed to evolve toward SIL and HIL workflows, autopilot integration and control-system testing.
One continuous model-development loop.
Vehicle architecture, available data, requirements and simulation objectives.
Aerodynamics, propulsion, environment, actuators and equations of motion.
Trim, open-loop dynamics, closed-loop control and real-time interaction.
Compare against CFD, flight-test or experimental data and iterate.
Not every vehicle fits inside a conventional aircraft model. We build the simulation around your physics.
