Preliminary engine design

Virtual view of future engine concepts

In order to improve the effciency, environmental impact and cost-effectiveness of aircraft engines, DLR is developing, analysing and comparing new engine concepts. A comparison between past and present engine generations clearly demonstrates the direction in which the development is heading: engines of the future will become bigger. This is partly due to fuel-saving concepts that are linked to an increase in propulsion effciency. Visitors to the DLR stand are invited to don virtual reality goggles to experience the differences up close. Virtual reality technology allows the user to interact with computer graphics in an entirely new way. On display are a standard turbofan like the one installed on the DLR research aircraft ATRA, as well as an innovative, counter-rotating open rotor (CROR). Visitors also have the opportunity to acquire insight into DLR’s process chains of the virtual, preliminary engine design. A separate computer demonstrates the simulation preliminary design environment GTlab, which is used to create the engine models presented in the virtual reality environment.
