David Gildfind’s research is primarily concerned with experimental hypersonics. His research interests include: expansion tube facility development; scramjet propulsion; planetary entry aerothermodynamics; and magnetohydrodynamic aerobraking.

David graduated as an aerospace engineer from RMIT University in 2001. He worked in industry on various aircraft platforms in Australia and overseas (GKN in Melbourne 2002-2003 on A340/A380; Australian Aerospace in Brisbane 2003-2005 on DHC4 Caribou; and Stork Fokker in The Netherlands 2005-2007 on F35-JSF and Gulfstream G6), and retains a strong interest in aircraft structures. He later completed his PhD and post-doctoral work in hypersonics at the University of Queensland (UQ), where he developed the capability for expansion tubes wind tunnels to simulate reallistic scramjet flight trajectories beyond Mach 10. His research in this area includes optimising free-piston driver operation, expansion tube flow condition development, and test flow characterisation.

David became a lecturer at UQ's School of Mechanical and Mining Engineering in 2014, and teaches into aircraft structures, design, and hypersonics. During this time David has initiated a new research program on Magnetohydrodynamic (MHD) aerobraking, which was awarded an ARC DECRA fellowship (2017-2020) to experimentally evaluate MHD aerobraking technology for a human mission to Mars. This work is now continuing in 2022 with the recently awarded three year ARC Discovery Project "Magnetohydrodynamic Aerobraking for Spacecraft Entry to Earth's Atmosphere" which David is leading. This will focus on the development of new MHD aerobraking technology to reduce spacecraft heating, leading to safer, more efficient, and potentially reusable spacecraft

Chris James' research is in the fields of experimental hypersonics, hypersonic aerothermodynamics, and planetary entry. His research combines two important and intertwined parts of these fields: the development and understanding of hypersonic test facilities and the performing and analysing of experiments in them. Chris' 28 journal papers, 2 technical notes, and 59 conference publications cover the design, improvement, and simulation of high enthalpy hypersonic facilities such as expansion tubes and shock tunnels, the application and improvement of physical, optical, and radio-based techniques performed on these facilities, non-equilibrium radiation measurements for entry into many planets in the solar system, re-entry observation measurements, and impulse facility ablation testing.

Chris graduated from Mechanical Engineering at UQ in 2012. Following this, he completed his PhD in the Centre for Hypersonics at the University of Queensland (UQ).

During his PhD he developed very high speed Uranus and Saturn entry conditions which were used to perform the fastest experiments which have ever been performed in an expansion tube, as well as developing expansion tube simulation and analysis codes which are now widely used in the Centre for Hypersonics and around the world. He also enrolled in a cotutelle program with École Centrale Paris in Paris, France, and after being awarded an Eiffel Excellence Scholarship by the French government, he passed a year on exchange in Paris, France. In France, Chris was working on developing the capability to perform radiating simulations to support his experimental work at UQ.

Post PhD he was employed in the Centre for Hypersonics helping to develop the X3R reflected shock tunnel, while also supervising and conducting expansion tube research on the X2 expansion tube at UQ.

In 2020, Chris took on a lecturing position for the year and was awarded an Australian Research Council (ARC) DECRA early career fellowship to study Mars return conditions with heated test models at UQ from 2021 to 2023. He was the 2020 recipient of the UQ EAIT Faculty Early Career Researcher Award and in 2021 a paper he presented was awarded the 2021 American Institute of Aeronautics and Astronautics (AIAA) Ground Test Best Paper Award at the 2021 AIAA SciTech Forum.

in 2020 he participated in the University of Southern Queensland (UniSQ) led re-entry observation mission of the Japanese Aerospace Exploration Agency (JAXA) Hayabusa2 re-entry over Woomera, South Australia and in 2022 he led the UQ contingent on the once again UniSQ led re-entry observation mission of the NASA OSIRIS-REx re-entry in the US.

He is now employed at UQ as a UQ Amplify Senior Lecturer where he continues to perform research in giant planet entry through an ARC Discovery Project which he received with his colleague Professor Richard Morgan and continues to develop and improve UQ's X2 expansion tube.

Chris lectures in the School of Mechanical and Mining Engineering at UQ. He lectures both hypersonics and space engineering, covering varied topics such as high temperature gas dynamics, hypersonic test facilities, rarefied gas dynamics, orbital mechanics, rocket trajectories, spacecraft design, spacecraft thermal and power management, and planetary entry.

He has written six popular science article for The Conversation with a more than 200,000 combined reads, and has been interviewed for Youtube and radio many times. He has given invited talks at the University of Oxford and the Engineers Australia Continuing Professional Development seminar series.

Prof David Mee's research interests are in Hypersonic and Supersonic Flow.

After completing his PhD at UQ, he spent five years as a Research Fellow in the turbomachinery research group at Oxford University in the U.K. He returned to UQ as an ARC Queen Elizabeth II Research Fellow in 1991 and joined the academic staff of the Department of Mechanical Engineering in 1993. He served as Head of the Division of Mechanical Engineering from 2007 to 2017, acting Head of the School of Engineering from January to July 2009 and Head of the School of Mechanical and Mining Engineering from July 2009 to February 2017. He retired in 2020 and is currently an Emeritus Professor in the School.

David's main areas of research are focussed in the field of hypersonics aerothermodynamics. He has undertaken much research on rapid response, stress-wave force balances, which are essential technology for categorising the performance of scramjet engines in transient facilities, such as shock tubes. He was a member of the team that conducted the first known wind-tunnel test in which a scramjet vehicle produced net thrust. He has also published on the transient processes in the latter stages of boundary layer transition in hypersonic flows.

Dr Tristan Vanyai's research interests are in the fields of hypersonic propulsion, aerodynamics, combustion visualisation and laser diagnostics, using both experimental and numerical techniques.

Dr Vanyai received his Doctor of Philosophy from The University of Queensland in 2018, after completing a Bachelor of Aerospace Engineering (First Class Honours) and Bachelor of Science double degree at Monash University in 2012.

His research focuses on fundamentals of hypersonic propulsion through the scramjet cycle. Robust combustion within low intake compression scramjets is a key technology enabler for hypersonic accelerator vehicles, and can be achieved through utilising techniques such as thermal compression. Dr Vanyai is examining the improvements to scramjet combustion due to thermal compression through experiments in the T4 Stalker Tube facility using advanced optical techniques and comparison with results from numerical simulations.
