The present thesis describes the results of the work made by the author at the Flight System Dynamic Institute (FSD) at the Technische Universität München (TUM).
The aim of the work is the development and the implementation of an Atmosphere Model in MATLAB/Simulink to be used in a flight simulation device.
The Atmosphere Model consists of four main subsystems: the International Standard Atmosphere (ISA) Model, the Wind Model, the Turbulence Model and the Gust Model.
A particular attention has been spent for the implementation of an additional model which allows to take into account the correlation that exists between the air velocities perceived in different points of the space: the Correlation Model. This model guarantees a more correct operation of the Turbulence Model in the case in which it is necessary to consider more aircraft flying in a restricted area.
After a brief initial introduction, the general characteristics of the Atmosphere Model and of the Correlation Model are presented.
In each chapter the subsystems of the Atmosphere Model are described in detail: requirements, modeling assumptions, scope of validity, limitations, algorithms for implementation, architecture specification, structural layout, verification plan and results.
Afterwards, the Correlation Model is explained in detail.
Finally, the last chapter is dedicated to the final assembly of the different parts.
