The Space West Region hosts three world class universities. Through these newsletters we will share highlights of the remarkable research taking place in these prestigious institutions. All three universities hold Impact Acceleration Accounts which are designed to help universities translate research to real-world impact. If you are interested in collaborating with a university, Space West can connect you to the right support.
Dr Chris Toomer is an applied mathematician who has specialised in aerospace engineering. She is a chartered engineer, and a Fellow of the Royal Aeronautical Society and the British Interplanetary Society. Completing a doctorate at Imperial College in global atmospheric modelling and a postdoc in astrophysics; Chris moved to BAe Systems to work on developing computational fluid dynamics and multiphysics models for compressible flows, specialising in hypersonic and supersonics vehicles. She has been a visiting Professor at NASA Langley and Old Dominion University, and worked subsequently at ETH-Zurich’s supercomputing centre running a computational modelling group. She is currently an Associate Professor at the School of Engineering at UWE, Bristol. [email protected]
Her current areas of research include hypersonics multiphysics CFD, ion thruster development, debris removal and in-space manufacturing of new alloys. The hypersonics and ion thruster modelling enable the simulation of the fluid and electric fields around the spacecraft from launch to orbit and return to Earth. As we continue to increase our launch capabilities with rockets and onto spaceplanes, it becomes increasingly important to model the physico-chemical effects around the vehicle as it travels through the atmosphere as well as studying the effect of the space environment on spacecraft whilst they are in orbit.

The debris removal and in-space manufacturing look to a future where we are operating in space for science and business activities. Debris continues to be a major concern and hazard, and its removal poses difficulties in terms of containing and removing the debris without causing more debris in the process as well as overcoming the international legalities. However the intent to remove existing debris and to ensure that we always have adequate spacecraft disposal plans shows the move towards sustainable, responsible and manageable space environments. Such behaviour paves the way for commercial activities including space manufacturing where microgravity conditions allow us to experiment with the development of new alloys, as well as 3D printing new space structures – possibly recycling the debris we can collect. As part of the space robotics we undertake at UWE are projects on debris grasping robots, robotic decomposition of debris and containerless field control for alloy production.
