In a country where aviation is seen as a problem and not a solution, few are the lucky and brave to be part of this wonderful sector. Among these few, thereare people like Marc Kuster who go beyond the simple fact of fly, and take their hobby to the point of designing and building aircraft.This thesis is part of the personal project of Marc Kuster, who more than 20 years ago designed a three-surface airplane with the intention that one day it would become a reality.The ODYSSEUS II, is the product of that design, and in this thesis parts of the airplane design and analysis process are shown. In particular, the thesis is based on the development of the different CAD models and later some first studies are made on the structural, aerodynamic and performance behaviourof the airplane.
