Recent advances in reusable launchers, autonomous robotics, and advanced materials could redefine how we design space structures. The ability to remotely assemble orbital systems from multiple launcher payloads would allow satellites to be much larger than ever before, enabling applications previously considered to be science fiction. Space-based solar power (SBSP) will require satellites with dimensions at the kilometre scale, using micron-thickness gossamer components to maintain feasible launch masses. Despite the contrasting scales of these large gossamer satellites (LGSs), their structural shape will need to be carefully managed to allow for efficient solar energy harvesting.  

This project will deliver novel methods for modelling and controlling LGS structural dynamics in the extreme orbital environment. The objectives are as follows:

1. Undertake in-depth review of the literature on SBSP structures, gossamer dynamics, and satellite control, leading to an informed trade-off of effective LGS configurations for SBSP.

2. Develop analytical and finite element (FE) models to investigate the extent and sources of nonlinear behaviour in LGSs.

3. Develop novel control strategies to stabilise LGS shape, orbit & attitude, including optimisation of the number/position/type of hardware.

星空体育官网 overview and Sponsor Information/Background: We have a long history in space systems, having undertaken space studies since the 1960s. Our current research has an overarching focus on sustainability in and from space, working closely with industry and agency partners to deliver cutting-edge solutions for real-world problems.

This project will be the first time the structural dynamics of gossamer structures have been considered at this scale, representing an important contribution to the state of the art for large space structures. The control systems developed will be designed to handle these complex dynamics, feeding directly into industrial SBSP and related designs, thus enabling their longer-term plans for commercial SBSP capable of outperforming terrestrial renewable energy generation.

This PhD has been designed to directly address the needs of leading industrial SBSP partners. The candidate will have the opportunity to present their work to these partners, and the supervisors will actively pursue possibilities for working with them directly. There is also a generous travel budget for attendance at one or more international conference per year.

The student will have the opportunity to join a vibrant community and team of researchers. They will develop important technical skills in spacecraft structural dynamics, controller design, and space systems. They will also develop ‘soft’ skills such as project/time management, research development, and scientific communication that will be applicable in a range of future careers. Should there be interest, there is also the possibility of developing teaching and supervision skills on our MSc Astronautics and Space Engineering programme.
