QinetiQ has experience in both wind flow simulations using Computational Fluid Dynamics (CFD) and aircraft 6-Degree-Of-Freedom (6-DOF) flight modelling. It was identified that coupling a built environment CFD flow simulation with an advanced aircraft flight model, incorporating the non-uniform flow field, could be used to create a realistic simulation of the response of an aircraft to wind flow near buildings.

CFD simulations of wind flow in the built environment and over aircraft are well-researched fields. For example, current research investigates the optimisation of UAS flight path planning using CFD simulations to highlight locations within the built environment that would be potentially dangerous for aircraft to operate. Demonstrating that we can model actual response of the aircraft in those areas was the target for this project demonstration.

For the simulation, a simplified geometry inspired by the hanger…
