What are digital twins?
A digital twin is a dynamic virtual copy of a physical asset, process, system or environment that looks and behaves identically to its real-world counterpart.
Check out our explainer page to dive deeper into how digital twins help teams make more informed decisions on how they design, engineer, manufacture, sell and operate physical things – from machinery to buildings.
Aerospace tasks are intrinsically complex. End products like aircraft and spacecraft are massively expensive to design and build, making it all the more imperative to get work done right the first time in order to avoid costly delays. From design and engineering all the way through to assembly and maintenance, digital twins improve decision-making by allowing teams to visualize and interact with computer-aided design (CAD) models and other datasets in real-time 3D.
Top use cases of digital twins in aerospace
- Product development and prototyping – 3D visualization enables designers, engineers and other stakeholders to better collaborate and evaluate design and manufacturing alternatives for complex systems.
- Simulation and training – Engaging training experiences in interactive 3D or augmented or virtual reality (AR and VR) enable better knowledge transfer and safer workplaces.
- Maintenance and operations – Creating work instructions in mixed reality from as-built models from design and manufacturing can simplify and optimize inspection, maintenance, and repair activities.
- Sales and marketing – Virtual showrooms and 3D product configurators empower buyers to explore every variation of aircraft and make purchasing decisions more confidently.
Boeing reimagines aircraft inspection and maintenance
Boeing created an AR-powered aircraft inspection application using a digital twin of one of its planes. The twin enabled this aerospace industry leader to generate over 100,000 synthetic images to better train the machine learning algorithms of the AR application.
At the start of a project, architects produce design materials, including renderings and models, to allow clients to evaluate and approve the design. The problem is there’s no shared, collaborative environment with stakeholders to make decisions in real-time. Communicating design intent during traditional reviews is a difficult process. Static 2D and 3D models cause details to be lost in translation, renderings aren’t flexible enough, and not everyone is on the same page. Digital twins solve these problems so there’s no more costly mistakes.
Top use cases of digital twins in architecture
- Design review – Architects and designers can easily bring design models into an immersive experience in AR and VR to facilitate interactive, real-time design reviews.
- Design visualization – Explore more design options and iterate faster, allowing for design issues to be identified and resolved more quickly.
- On-site AR – Overlay models in 1:1 AR at scale on the jobsite to effectively communicate design intent to stakeholders.
