Modern engines should be as quiet and emission-free as possible without compromising on power. For decades, this has been the focus of DLR's aeronautics research institutes, who have been working on developing better engines and testing them using various test benches. But for some time now, there have been new components to this research – simulations and digital models. These innovations allow researchers to digitally test new concepts in advance without the need for costly prototypes, speeding up the development of new engine designs. In this issue, DLR researchers Stanislaus Reitenbach and Kai Becker talk about the role that the virtual engine could play in the future
