Linear modeling of tiltrotor aircraft (in helicopter and airplane modes) for stability analysis and preliminary design

This thesis investigates the linear state space modeling of a tiltrotor aircraft by modifying an existing MATLAB routine which is used for preliminary (helicopter) stability and control analysis. The modifications consist of changing existing script files along with adding new ones. The modification...
