Moving Model Rig - technical specifications
The TRAIN (Transient Railway Aerodynamics INvestigation) Rig belonging to the University of Birmingham has been developed specifically for conducting experimental investigations into railway aerodynamics but is also suitable for studies into road and ground vehicle aerodynamics and other aerodynamic applications. The specifications for the rig include:
- The rig is housed in a purpose built enclosure on the rtc Business Park, London Road, Derby
- The overall length of the facility is 150m with a 50m long test section
- Nominal model scale - 1/25th for train testing, but larger models can be used
- Model speed - up to 75m/s
- Propulsion system - two rubber catapults, one at each end of the rig, allowing bi-directional and passing tests
- Track systems - three tracks are provided, two at the standard British railway system track spacing scaled to 1/25th and a third at a wider spacing allowing for wider models
- A cross flow facility is provided adjacent to the test section to permit tests to be carried out on the effects of side winds on vehicles and the influence of winds on vehicle slipstream flows
- A wide range of pressure transducers and velocity measuring probes of different sensitivities and types are available for measurements.
The facility also includes a tunnel structure allowing tests within confined spaces to be carried out.
We can source models of both vehicles and other structures, for testing on the rig. Tests can involve measurements on the moving vehicle as well as on stationary positions and models at the sides.
