Development of a Flight Dynamics Model of a Flying Wing Configuration
Master thesis in Aeronautical Engineering Development of a Flight Dynamics Model of a Flying Wing Configuration Candidate Supervisor Jacopo Tonti Prof. Guido De Matteis External supervisor Prof. Arthur Rizzi (Kungliga Tekniska högskolan) Academic Year 2013/2014 cbn 2014 by Jacopo Tonti Some rights reserved.

An international group, under the initiative of the NATO RTO AVT-201 Task group, titled “Extended Assessment of Reliable Stability & Control Pre- diction Methods for NATO Air Vehicles”, is currently performing intensive analysis on a generic UCAV configuration, named SACCON. In this thesis the stability and control characteristics of the SACCON are investigated, with the purpose of carrying out a compre- hensive assessment of the flying qualities of the design. The study included the generation of the complete aerodynamic database of the aircraft, on the basis of the experimental data measured during TN2514 and TN2540 campaigns at DNW-NWB low speed wind tunnel. Moreover, system identification techniques were adopted for the extraction of dynamic derivatives from the time histories of forced oscillation runs. The trim of the aircraft was evaluated across the points of a reasonable test envelope, so as to define a set of plausible operative conditions, representing the reference conditions for subsequent linearization of the dynamic model. -

APPENDIX C5: Design of Unusual Configurations
APPENDIX C5: Design of Unusual Configurations This appendix is a part of the book General Aviation Aircraft Design: Applied Methods and Procedures by Snorri Gudmundsson, published by Elsevier, Inc. The book is available through various bookstores and online retailers, such as www.elsevier.com, www.amazon.com, and many others. The purpose of the appendices denoted by C1 through C5 is to provide additional information on the design of selected aircraft configurations, beyond what is possible in the main part of Chapter 4, Aircraft Conceptual Layout. Some of the information is intended for the novice engineer, but other is advanced and well beyond what is possible to present in undergraduate design classes. This way, the appendices can serve as a refresher material for the experienced aircraft designer, while introducing new material to the student. Additionally, many helpful design philosophies are presented in the text. Since this appendix is offered online rather than in the actual book, it is possible to revise it regularly and both add to the information and new types of aircraft. The following appendices are offered: C1 – Design of Conventional Aircraft C2 – Design of Canard Aircraft C3 – Design of Seaplanes C4 – Design of Sailplanes C5 – Design of Unusual Configurations (this appendix) Figure C5-1: A Marske Pioneer II-D, single seat flying wing in flight (photo courtesy of Jim Marske).

The term is surprisingly hard to define. -

I thank them for their hard work. The members of the Board of Directors are: • Sylvain Bourque, the Eastern Zone Director and SAC President, started gliding in 1994. Since then he has been an active member of AVV Champlain involved in training, towing, and in accounting as treasurer. He is a SAC Class 1 glider instructor and owns his CPL. He has organized the winter French ground school in the Montreal area since 1995. He is an aeronautical radio licence examiner, aviation language proficiency test examiner (E-F), and an authorized person for gliding licensing. Sylvain owns a Pegase with two other partners. Sylvain is a field production cameraman instructor and supervising technician for CBC/Radio-Canada in Montreal. I’m proud to be part of this Board that has such a good variety of backgrounds and a huge involvement in the soaring community. • George Domaradzki is the director for the newly formed Eastern Ontario Zone. This zone consists of Gatineau Gliding Club, Rideau Valley Soaring, Bonnechere Soaring and Montreal Soaring Council (which is actually located in Eastern Ontario.) George has been flying gliders since 1998 and has been an instructor since 2004. He is currently the president of Rideau Valley Soaring. George also coordinates the Ottawa Area Glider Pilot Ground School every alternate year and had given various theoretical lessons.
