ofmodelling Every component in an aircraft plays a vital role.


Paul Schreier peers into the diversity of such components and the modelling software that helps designers create and optimise them


of an aircraft body or wing to optimise its performance. However, modelling software and HPC are being applied to many other areas to improve aerospace engineering, whether in advanced research, manufacturing or even HPC load scheduling at large manufacturing companies. The benefi ts can be considerable. In a

hen it comes to aeronautics and areospace applications, we’re well aware that simulation can be used to optimise the design


industry marketing director at Ansys, states that there is clear overlap between the quality, cost and time pressures that the UAS design and development community faces and the benefi ts of engineering simulation. He notes that as UAS capabilities continue to grow ever more complex for individual projects, engineering simulation will add the most value when: It is applied to all aspects of UAS design (requires fl uid dynamics, structural mechanics, electromagnetic, thermal simulation capabilities, not just one or two in isolation);


The interaction of the physics at a system level is included in the analysis (for example, fl uid and structures for wing fl utter, structures and electromagnetics for load-bearing antenna design, structural and thermal for component thermal stress analysis);


The workfl ow is seamless, integrated across physics and with existing tools such as CAD and PLM; and


Physics-based optimisation is performed across the design envelope.


He then adds that research performed by the US Department of Defense revealed the staggering impact that engineering simulation can have. A three-year study published in 2010 reported that ‘for every dollar invested [in the software and computing infrastructure to support simulation], the return on investment is between $6.78 and $12.92.’
