The same can be said about flapping flight. The Delft University of Technology started to develop a flapping wing MAV in 2005, ”DelFly”, which relies on a flapping biplane wing configura- tion for thrust and lift generation. DelFly has evolved significantly during the last years. At the time of writing there are already three version of DelFly; DelFly I, DelFly II and DelFly Micro. The test subject of this study is DelFly II because of its stable and broad flight envelope. The aim of this study is to improve flight performance of the DelFly II. Hereto, in this thesis report, a wing geometry study is performed in order to improve the aerodynamic performance of the wing and the driving mechanism is improved in order to increase the efficiency of energy transfer from the battery to the movement of the leading edges. The current study resulted in a increase of thrust-to-power ratio of 5% due to the wing design and 20% due to the new crank-shaft mechanism To reference this document use: http://resolver.tudelft.nl/uuid:03f73d85-3684-499c-affc-637d2a5971bf Part of collection Student theses Document type master thesis Rights (c) Bart Bruggeman Files PDF MSc-Bruggeman.pdf 6.63 MB Close viewer /islandora/object/uuid:03f73d85-3684-499c-affc-637d2a5971bf/datastream/OBJ/view
