University of Leicester

Part of the University of Leicester Department of Physics and Astronomy, the Space Research Centre, which includes the Space Science and Instrumentation Group and the Earth Observation Science Group, develops scientific instrumentation and systems, working closely with such organizations as NASA and the European Space Agency.

Mission-critical performance


It costs in excess of $30,000 per kilogram to launch a piece of hardware into space, and there is little opportunity to fix problems once it has left the earth. In order to meet performance criteria, scientists and engineers at the University of Leicester Space Research Centre, (also called Space Research Centre or just Centre for short) rely on NX™ software and Teamcenter® software to design, simulate and manufacture to exacting standards.

The Centre has been involved in space research for 50 years, working closely with partners, such as National Aeronautics and Space Administration (NASA) and the European Space Agency. It develops sensors, telescopes, spectrometers and other scientific instrumentation, and associated mechanical structures, electronics and power generation systems. Its project portfolio includes missions to study the Earth and other planets in our own solar system and beyond, as well as other stars and galaxies in the universe. With extensive facilities, including test laboratories and on-site manufacturing, it also conducts interdisciplinary research in Life Sciences, counterfeit technologies, art history and medicine. Staff and students are using NX and Teamcenter, both from Siemens PLM Software, to underpin the lifecycle of projects, such as the first European rover mission to Mars, due to take place in 2018.

“Sending equipment to space involves an extensive development program,” says Dr. John Pye, who manages the Space Research Centre. “Hardware must not only be proven to perform as required, it must have rigorous traceability and quality control. This all has to be done within strict cost and schedule constraints.”

Fifteen years ago, the mechanical design and analysis team started using NX I-deas, which is an earlier version of what is now NX.

According to Piyal Samara-Ratna, computeraided design (CAD) administrator and mechanical engineer at the Space Research Centre, the group was primarily using 3D modeling tools to develop simple configurations, and then using these for thermal and structural testing. “The majority of detailed design was done purely in 2D and manufacturing was performed using either third-party software
