D20.1 – Improved aerodynamic, development & demonstration intermediate report No. 1

The aim of this report is to give insight into the topics and tasks of work package 20. The content and time schedule of the two tasks is defined and information about the distribution of work between the partners as well as the methods which will be used are given.
The WP is divided into two tasks, whose motivation and aims are explained. First results and the relevant methodologies are clarified.
Within the task 20.1, the work intends to expand the current state of the art and work towards new regulation requirements that could enable virtual certification in the foreseeable future. The aerodynamic topics, on which the studies will be based on, were defined and a generic train model was designed, which allows the study of the different methods and the validation of numerical results with experimental tests. However, no full-scale data of the generic train will be available. A comparison between numerical results gained with the developed method and full-scale data of a regional train will be delivered by a partner of the WP for validation purposes in the later progress of the WP.
The task 20.2 is dedicated to the optimisation of the train’s roof equipment with regards to noise and mainly drag and therefore fuel consumption and CO2-emission. The same generic train geometry will be utilised for the study of optimal train roof equipment placement. A generic pantograph was generated to give insight into the flow around different parts of the pantograph as well as the forces on the pantograph. The power transfer efficiency is to be optimised by adapting the pantograph aerodynamics.
All tasks are according to the plan, no delays have to be reported.
