The Department has excellent facilities for research and teaching. Research facilities support computational and experimental projects in fluid mechanics, structural analysis, composites, optimisation and control and aircraft design. Experimental research is supported by well appointed laboratories and wind tunnels, some of the equipment being unique in this country.
Enquiries about the use of facilities may be directed either to the Department Operations Manager Ms Molly Ip , the Wind Tunnel Manager, Dr Nigel MacCarthy or by contacting the relevant facility manager, listed under each facility.
Departmental facilities available for commercial testing
Given the highly computational nature of the department, it is not surprising that computing facilities are outstanding. Research activities make use of two High Performance Beowulf clusters, an Itanium server and a large number of Linux and Unix workstations, as well as Windows PCs. In addition, research groups have access to College-wide and external parallel facilities.
There are two teaching laboratories open to all department members. The main teaching laboratory consists of 44 HP PCs running Linux and Windows. The second teaching cluster has 28 computers, 18 of which are dual-boot and 10 are Linux-only PCs used mainly for projects. Both computer rooms operate between the hours of 7.00 and 22.00, seven days a week.
The two clusters and all the research workstations are linked via 100Mbit links to the 1Gbit College network and the Internet.
Peripherals available for public use include several high resolution laser printers, including a colour laser printer.
Undergraduates make extensive use of the computer laboratories for classes such as an in-depth programming course, numerical methods courses and Computer Aided Design courses using a three dimensional solid modeller package. In addition, it is used for projects which range from Finite Element analysis to Aircraft Design and Computational Fluid Dynamics.

Full-motion flight simulator
The Department of Aeronautics has its own full-motion flight simulator. This is a highly re-configurable simulator that can be programmed to accurately simulate almost any type of aircraft. It is equipped with a two-seat cockpit with fully programmable glass display instrument panels, realistic dual side-by-side flight controls, systems switches, full radio navigation stack, replaceable multi-engine throttle quadrants and a full autopilot. A 140-degree wrap-around external visual system provides a realistic representation of the surrounding terrain, major topographical landmarks and accurate airport runway layouts for all the airports around the world.
The system is also provided with a full aeronautical navigation database and a day/night weather generation capability. The cockpit is mounted on to a six-degree of freedom all-electric full-motion platform which significantly enhances the flight simulation realism. An instructor operating station is also available, equipped with controls and displays for setting up different flight scenarios, changing the weather, inducing aircraft system malfunctions, and for flight monitoring in general. The flight simulation is controlled by six computers.

The Department has a comprehensive series of wind tunnels, covering speeds from a few metres per second to Mach 9. There are 5 general purpose low speed tunnels with working sections from 0.4 to 16 square metres. The complete list of facilities is as follows:
The 10x5 low speed wind tunnel
This tunnel has two large test sections and the lower section is fitted with a moving floor and is used extensively for F1 racing car and saloon car testing. It is also fitted with equipment to simulate the atmospheric Boundary Layer for wind engineering of buildings and other structures (1:200 scale and upwards).
This facility is part of the National Wind Tunnel Facility and is capable of road vehicle and racing car aerodynamic testing. The lower test section is 3m x 1.5m x 20m long and the upper section 5.7m x 2.8m x 18m long. Wind shear and turbulence of the atmospheric environment can be simulated in this for studies of pollution and the wind loading of buildings and structures. The tunnel has a sophisticated 3-axis probe traversing mechanism, non-intrusive particle image velocimetry (PIV) equipment and the control and data processing are fully computerised. For more information contact the wind tunnel manager below and visit the 10x5 wind tunnel section.
The T2 low speed wind tunnel
This tunnel is temperature regulated and fitted with a 3-axis precision traverse. The following are its main characteristics:
- 1.6m x 1.1m cross-section (4m length)
- 40m/s air speed
- 3-axis traverse mechanism
- Computer control
- Temperature regulated
Other wind tunnels
There are also six wind tunnels ranging in capability and test section size with speeds of up to Mach 9. These are:
- Low speed T1 wind tunnel, top speed 40 m/s, with 0.91m-square x 5m long working section and 3-axis precision traverse. The flow in this tunnel has a very low turbulence level.
- 18" Closed circuit wind tunnel with a 55m/s top speed and a 0.45m square test section which is 2m long
- Supersonic wind tunnel 0.15m x 0.15m cross sectional area capable of up to Mach 5 flows for 30 secs duration
- Hypersonic gun tunnel. This is a short duration facility with a nozzle exit diameter of 0.34m. It operates at Mach 9 and achieves unit Reynolds Numbers in excess of 40 million; it is thus suitable for the study of transition and turbulent boundary layer flows.
- 18" Open Jet wind tunnel with Centrifugal fan, precision AC drive system and traverse. Speeds up to 30 m/s.
- 10" FloTek open jet wind tunnel for system preparation, probe calibration etc.
We also have various blower wind tunnels of varying cross sectional area for small scale aerodynamic experiments.
Wind tunnel manager: Dr Nigel MacCarthy
The Department has a facility that uses water as the working medium and has been developed especially to study the wave forces on sea-based structures:
- A 9m long water channel with 0.6m-square section and computerised towing carriage. This flow channel is particularly useful for flow visualisation.
