The design and integration of the propulsion system is known to be an interesting, multi-disciplinary challenge in aircraft design projects. Especially for new aircraft configurations, it is important to gain a lot of knowledge in the preliminary design stages. An example of such an unconventional configuration is the box-wing aircraft examined by the PARSIFAL project. Therefore, a Knowledge Based Engineering approach towards engine design and integration is developed in this thesis. This new approach allows to consider the propulsion discipline in multi-disciplinary design and analysis routines. By employing the ParaPy software, the complete aircraft geometry can be created and subsequently subjected to aerodynamic analyses in VSAERO. The developed tools are validated and employed to explore the design space offered by a closed-wing arrangement. Based on this exploration, a turbofan system and installation location are recommended for the PARSIFAL aircraft. ...
As more and more people choose the airplane as a means of transportation, the aviation industry faces new challenges in order to fulfill the increasing demand, while decreasing the costs and emissions. In this report, the authors present a design of a narrow-body aircraft that is meant to provide a 30 % direct operating costs reduction, as well as a 20 % reduction in NOx and CO2 emissions while being ready for market introduction by 2030. Furthermore, the aircraft should provide a noise reduction of 10 % which translates to a reduction of 29 [EPNdB] and it should house 177 passengers. ...
