Biography

Patrick Harkness is from Ballyclog, in Co. Tyrone. Patrick obtained a MEng degree in Aeronautical Engineering from The Queen’s University of Belfast in 2003 and a PhD in space debris mitigation from Cranfield University in 2007. He is now Professor of Exploration Technology at the University of Glasgow.

Research interests

Patrick has research interests in the behaviour of granular materials. We have shown that vibration can reduce penetration forces, improve the performance of augers and drills, and even achieve vertical uplift in confined spaces using our pulse-elevator concept.

The purpose of this research is to enable the exploration of extreme environments, both on Earth and in space. This includes the development of robotic devices with self-assembling drillstrings that can take and containerise samples, hardware for the exploration of the bedrock underneath the antarctic ice sheet, concepts for deep-drilling on Mars, and many others.

Another theme of work is access to space. We have been working on the autophage rocket system, from the first firings in Ukraine to the current tests of our Ouroboros-3 engine at the MachLab, which is our own hotfire facility. We also focus on rocket education, from the university rocketry society to the R2T2 consortium: the UK's first integrated doctoral-level rocket propulsion training programme.

Finally, space-deployables have applications in solar sailing and sustainability, and the dynamics of unfolding structures can always be improved!

Grants

I would like to thank those organisations which have very kindly funded our work. These include UK Research and Innovation, the UK Space Agency, the UK Ministry of Defence, the European Space Agency, the European Union, and many others. I would also like to thank the British Antarctic Survey for their logistical, professional, and scientific support during testing in extreme environments; and the Machrihanish Airbase Community Company for similar support to rocket hotfire campaigns.

Teaching

Patrick's courses include the following:

Dynamics 3

Patrick's material on this course examines the behaviour of free and forced vibrating systems, considering the effects of friction, damping and resonance.

Vibration 4

Patrick's work on this course focusses on the practicalities of vibration analysis, especially hardware and signal processing.

Space Systems 5

This course provides an introduction to key spacecraft subsystems, as well as the space environment and space law.
