My research will focus on the conceptual boundary layer ingestion (BLI) aircraft, aiming to reduce exhausts (CO2, NOx and noise, etc.) for creation of a sustainable society. This study is financed by Clean Sky 2 Joint Undertaking in the European Union. I will work with the Chalmers group to develop an advanced method to design and optimize engines for various conceptual BLI architectures. The method will be implemented based on an in-house code GESTPAN. The method can take into account the specific features of BLI installation. At the end of the project, the method is expected to be beyond the art.
