Alternative approaches to rear end drag reduction Technical Report Torbjö rn Gustavsson Stockholm 2006 KTH, Department of Aeronautical and Vehicle Engineering Royal Institute of Technology TRITA-AVE 2006:12 ISSN 1651-7660 www.kth.se 1 Preface This paper was originally formed during my stay at KTH Startupfactory in the autumn of 2003. The intent of that stay was originally to make a commercial product out of the patent I received the same year. The proj ect turned into research and one result is this paper. For further inquires in the area I can be reached by e-mail: torbjorn@ Sincerely yours Torbjörn Gustavsson Reaching for the stars… 2 Acknowledgements Above all I would like to thank Kim Nouira for his support during my stay at KT Startupfactory. Second I would like to thank all my friends and family, especially my brother and mother, for support and feedback during development of this project. I also would like to thank John C Lin at NASA Langley Research Centre who is the source of many of the reports I used as reference material. e has produced an amazing amount of work in very interesting areas and I also would like to thank him for providing some of his material free of charge. Hopefully I will get the opportunity to meet him some day. Last but not least I would like to thank Tomas Melin and Arthur Rizzi at the Department of Aerodynamics at KTH for supporting the idea that the subject I buried myself so deep in could end up in something else than just knowledge, that is this report. Without them this work would never have taken place. 3 Abstract This report begin
