The Virtual Engine Platform group integrates all numerical methods in one platform – the virtual engine. This platform offers unique possibilities of optimization on all levels, from component level up to full engines on the basis of coupled simulations (structure-mechanical, fluid-mechanical, thermodynamical, aeroelastical). The different methods cannot be centralized. Connected by interfaces, they combine to the virtual engine, which can be adapted to be a digital twin of a particular engine and calculate key performance parameters, e.g. Performance, weight, lifetime, efficiency, lifetime and reliability.
