The flight stream rig allows a simulation of propulsion systems under dynamic testing. The system uses the compressed air flow from the Gnome turboshaft rigs, which is fed through a twin ejector system to entrain large amounts of ambient air. This is settled in a large plenum chamber before it exits via a nozzle which comprises the working section. This nozzle can be shaped to suit the application.
