Direct Lift Control for Improved Automatic Landing and Performance of Transport Aircraft LOWELL

Over the last years a multidisciplinary aircraft predesign process chain was established at the DLR, including different numerical tools for the modelling and structural sizing of fuselage structures. To improve the flexibility and performance of this structural analysis part in the MDO process a new tool development has been started in 2016 called “Parametric Numerical Design and Optimization Routines for Aircraft” (PANDORA). The PANDORA framework is using the interpreted high-level programming language Python and is focused on using dedicated open-source packages. Within PANDORA a lot of new packages have been implemented, like a new interface to access CPACS data, a python based FE pre- and postprocessor, a FE data converter to build an interface between PANDORA and different FE solver and a visualization interface using “The Visualization Toolkit” (VTK). Some further packages to generate a FE model based on a CPACS file using the geometry core “Open Cascade” (OCC) and a new FE sizing algorithm is also under development. To simplify the usage of PANDORA and to keep it comprehensible - a graphical user interface (GUI) has been added using the PYQT toolkit. In this paper the current state of the PANDORA development is presented and initial applications are shown.

This article introduces the scope and activities linked to an end of studies project. This project is a collaboration between UNIZA and ENAC and includes work of Pascal Roches and Thierry Druot on top of the student and his UNIZA tutor mentioned above. This article describes the environment of ENAC and the particular department CADO in which the project is being accomplished. It also sets the definition of the project, its main goals and deliverables. Finally, it shows methods of the work that has been done so far, that is the completion of the database of 324 commercial aircraft, which took the largest amount of time so far. It also introduces the software, which will be used to define different models required to calculate initial dimensions and performance parameters of battery or fuel cell concept aircraft.
