THESIS STUDY               


1.6 Contents of the Thesis Study

    In the second chapter, the detailed summary of the conceptual design study of this new concept is discussed under related topics, such as airfoil and geometry selection, initial sizing, propulsion and fuel system integration, etc. The evaluated characteristics of this aircraft are presented in the relevant tables. Three view drawings in hover and cruise flight modes are presented. 

    In third chapter, the flight mechanics equations of motion are presented in order to model this aircraft. Usual rotational equations are modified to take account into the angular momentum changes due to moving parts, i.e. ducts and propellers. 

    In fourth chapter, trim flight conditions are obtained. For this purpose a trim program is written which minimizes a cost function. Various trim flight conditions for hover, transition and cruise are obtained and the aircraft stability at these particular flight conditions is discussed.

    In fifth chapter, automatic flight control system designed with classical design techniques including block diagram representations and root locus analyses and modern control techniques including eigenvalue assignment and linear quadratic regulator design is presented. Finally, conclusions are given.
