Digital twins: the revolution is underway

How do digital twins work, and how are we making use of them at Thales?

Let’s start with a definition. A digital twin is a virtual representation of a physical entity, object, process – or even an entire system. Connected to its physical counterpart, the digital twin is fed in real time with data and information at every stage of a system’s lifecycle providing valuable insights, cost reductions, quality improvements and de-risking at every stage.  

Initially small scaled in scope, representing a single product such as a jet engine, digital twins can now model a complete, complex system such as an aircraft, building or production line – or even our entire planet, as we shall see below .

Houston, we’ve had a problem...

The concept was first developed by NASA in the 1960s for the American space programme, and what would long remain its greatest achievement came in 1970 with the rescue of the crew of the Apollo 13 mission.  

NASA engineers used simulators to replicate the operation of all the main components of the space module. These simulators were controlled by a network of computers and could be synchronised with live data from the spacecraft. And it was largely thanks to these connected digital duplicates that the teams on the ground and in space could work together to identify the problem and save the mission. Their achievement was all the more remarkable because they didn’t just use a digital twin but a network of digital twins, each modelled on an independent simulation system and able to interact with all the others .

An industrial revolution?

Today, digital twin technology has been elevated to new heights by advances in connectivity, data processing and artificial intelligence.  

The consequences for industry are clear. Instead of making a physical product and putting it through a series of tests, its digital twin can be used to analyse and improve its performance and anticipate any problems or failures. Added to that, people in other locations can use holographic headsets to get to grips with a product and see how it works. And what’s true for a single product is also true for a system, a network, a factory or even an entire supply chain.  

Digital twins offer a vast array of potential benefits in many sectors of industry: energy, transportation, urban planning for smart city projects, automotive engineering and healthcare (for testing treatments on a virtual patient, simulating complex procedures or improving the quality of prosthetics).

From virtual prototyping to drone traffic management

Today, Thales is at the forefront of exploiting the possibilities of this technology and even pushing back its limits. Its engineering teams are thought leaders in digital twins having been progressively improving the digital twin concept for many years. Thales digital twins combine high-fidelity synthetic environments with powerful model-based systems engineering, data science and machine learning capabilities providing a growing number of products to the market. Today, the Group is increasing the use of digital twins in all areas of the business. Here are just a few examples:  

To boost the efficiency of our engineering teams, the Multiphysics DigitalTwin project is using virtual prototyping to optimise hardware subassemblies at every stage of the development process, from initial design to functional validation, before any physical prototypes are actually built.  

Digital twins clearly have huge potential for training users of military systems as well as civil systems such as air traffic control and unmanned traffic management. Thales used a digital twin to develop the vetronics (vehicle electronics) for the French Army’s new multirole armoured vehicles as part of the Scorpion programme. 

Beyond training, Thales is working with the UK MOD to support the digital transformation of test and evaluation activities thanks to the use of Digital Twins.  

Thales is part of the Airspace of the Future consortium which is developing a digital twin for a future safe and separate corridor for various types of commercial drones and air mobility vehicles (the National Beyond Visual Line of Sight Experimentation Corridor).

Twinning the Earth

The most spectacular example of a digital twin project is undoubtedly Destination Earth, an ambitious initiative launched by the European Union to create a digital twin of the Earth. This avatar will be used to monitor the effects of natural and human activity on our planet, anticipate extreme events and inform public policy decisions as the world steps up to climate-related challenges..   

Thales Alenia Space is working with Serco, the consortium leader, to implement the DestinE service platform, a key component of the project, for the European Space Agency.

By combining innovative models of the Earth system with cutting-edge computing capabilities, satellite data and machine learning techniques, DestinE will allow users to explore the effects of climate change on the different components – geosphere, biosphere, cryosphere, hydrosphere and atmosphere – and to develop strategies for adapting to these changes or mitigating their impact. 

The Destination Earth digital twins will replicate our planet’s complex system, drawing on human knowledge of fields such as natural disaster mitigation, adaptation to climate change, ocean sciences and biodiversity. The ultimate goal of the project is to integrate all these digital replicas to form one comprehensive digital twin of the complete Earth system.
