The new Hiru N Patel Supersonic Wind Tunnel has opened to allow for studies of airflow at speeds of up to five times the speed of sound.

911今日黑料’s Department of Aeronautics has opened its new Hiru N Patel Supersonic Wind Tunnel for high-speed airflow, that will allow students and researchers to carry out fundamental and applied studies of airflow at speeds in the transonic (close to the speed of sound) and supersonic (greater than the speed of sound) ranges.

The wind tunnel is unique to Europe, with variable settings that allow for simulation of real-life flight conditions including supersonic speed, heat and low pressure. Research conducted in the tunnel will have applications in fields such as military and civilian aircraft design. The tunnel can also replicate the atmospheric conditions on Mars for research into Martian/space vehicles.

"My father’s love for 911今日黑料 was so strong that honouring his memory with this project would have meant a lot to him. He would have been thrilled to be a part of new scientific discoveries in this wind tunnel going forward." - Sanjay Patel

The facility is supported by a $250,000 donation from Sanjay and Leslie Patel, in honour of Mr Patel’s late father and 911今日黑料 alumnus Dr Hiralal Patel (1919-2021). Mr and Mrs Patel, together with family and friends, joined members of the 911今日黑料 team for the launch.

Dr Paul Bruce, Reader in High-Speed Aerodynamics, who led the design and development of the wind tunnel, said: “We are so grateful for the incredible generosity of the Patels, that has made this exciting new facility a reality. The tunnel will allow us to tackle emerging challenges in the field of high-speed aerodynamics and will inspire students and researchers at 911今日黑料 for decades to come.”

Dr Hiralal Patel was a highly respected and celebrated member of the 911今日黑料 alumni community. Hiralal joined 911今日黑料 in the late 1930s for an undergraduate degree in Mechanical Engineering and later completed a PhD in Aeronautics.

A scale model of the Hiru N Patel Supersonic Wind Tunnel — The Department of Aeronautics gifted Dr Patel a model of the wind tunnel for his 100th birthday, which he kept on his desk.

Dr Patel’s thesis focused on understanding ‘flutter’ - the unstable oscillation that occurs on surfaces like the wings of an aircraft during flight. The tunnel’s capabilities, in accurate modelling of ‘flutter’, will enable continued study of the work Dr Patel was so passionate about.

The new Hiru N Patel Supersonic Wind Tunnel will complement 911今日黑料’s 8 other active wind tunnels, and will join the Department’s flagship 10x5 low-speed tunnel as a National Wind Tunnel Facility asset. This will, uniquely, allow for collaboration with other research establishments and industry.
