Aircraft Stability Analysis Including Unsteady Aerodynamic Effects

iAcknowledgmentsAll that I struggled to accomplish in my academic life was also part of a tentative effortto honor all of my former teachers. The first of them was my retired uncle Dermeval, whotaught me how to read by patiently reading comics for me. Among the others, I wouldlike to mention the devoted Chemistry Professor Adauto de Oliveira, my father, who wasthe first person to bring the beauty of Science to my attention. Another person that Ishould mention my gratitude to is schoolteacher Laudelina, my mother, who took herown life as an example and taught me to persevere and never give up, no matter howadverse the situation could be.The times that I spent working on this research certainly are among the most challengingof my life in many ways. During these tough times of my Ph.D. program, I certainlyreceived support from God, Who helped me through several individuals. Very importantsupport came from the remaining members of my family, especially from Aurea, the twoEstellas, Maria, and Priscila. They helped me in so many ways that it is impossible to listeverything here. I would like at least to thank them for always keeping my positiveattitude toward the end of this program. Fundamental support gave me the late Dr.Frederick Lutze, my first advisor in this research. He introduced me to this problem andgave me the initial guidelines to solve it. He also provided the grant that funded most ofmy stay in Blacksburg and made it possible for me to pursue the Ph.D. program. Veryimportant guidelines were also given to me by my committee Chair, Dr. William Mason,who kindly lent me his multidisciplinary experience and advised me since Dr. Lutzepassed away. I would like to thank all the committee members for the revision of thisdissertation and valuable suggestions. I shall acknowledge the excellent job that theGraduate Program Coordinator in the Aerospace and Ocean Engineering Department,Ms. Hannah Swiger, did when she put everything together for my final examination. Mystays in Blacksburg were possible also because of the leaves of absence granted by myemployer, the Brazilian Air Force’s Institute of Aeronautics and Space (IAE), after the
