碩士 === 國立交通大學 === 控制工程系 === 85 === The objective of this thesis is to design the library subroutines of wind models like turbulence,microburst,and many other special winds.We also clearly propose the way to modify the program of the jet-plane,which is proposed in AIAA,so that the wind effects can be applied to the aviation process of AIAA plane.Moreover,our design can be primarily used for testing the designs of airplanes and their flight controllers.In this thesis,we consider three types of abnormal winds and their mathematical models.The first one is the discrete gust wind model,including updraft,downdraft,head wind,tail wind,and side wind.The second one is the atmospheric turbulence model.We use the von Karman spectrum,Dryden spectrum,and a vortex array to generate this type of wind models.The third one is the microburst.We have built up five samples for this model:such as, a simple downdraft model,a single ring vortex model,a multi-ring tilt vortices model,and DFW microburst models which are provided by the reconstruction of DL-191 and AA-539.We have generated a set of library subroutines for implementing the wind models.For verifying our design,we use AIAA plane as the example plane.The wind effects to the plane have been computed and shown in this thesis.
