The work

Long before a vehicle flies, it flies thousands of times inside a simulation: a model of its dynamics, its sensors and its environment, run in software and eventually on real flight hardware wired into a rig that cannot tell the difference. Simulation and modelling engineers build and maintain that infrastructure, the physics models, the hardware-in-the-loop rigs, the fidelity that makes a simulated failure worth taking seriously, so every other engineering team has somewhere honest to test.

A typical day

• 01Build and validate physics models of vehicle dynamics, sensors and environment
• 02Maintain hardware-in-the-loop rigs that run real flight software against a simulated vehicle
• 03Correlate simulation results against real test or flight data
• 04Support other engineering teams running their own test campaigns against the model

How people get in

• Engineering, CS or physics degree

  Strong programming ability combined with real physics or dynamics knowledge is the actual bar, whichever department it came from.

How it unfolds

1. DegreeEngineering, computer science or physics, with real numerical methods and software engineering both.
2. Years 1-3Building and validating individual models: a sensor, an actuator, a piece of the environment.
3. Years 4-8Owning the simulation architecture a whole programme designs and tests against.
4. LaterSimulation lead, or into flight software or GNC with an unusually strong grip on the vehicle model.

Is there a job in it

The hard parts

A simulation is only useful if people trust it, and trust erodes fast the first time a model misses something the real hardware does. Hardware-in-the-loop rigs are complex systems in their own right, and keeping one running and credible, in sync with a vehicle design that keeps changing, is a permanent, unglamorous maintenance job most people only notice when it breaks.
