Study of the flight dynamics of a kite

Abstract : The PhD focuses on the study of electric generators using a kite to capture wind energy. These systems generate wind energy without having to build the towers and foundations are needed to build conventional wind turbines.These systems started being studied around ten years ago, twenty companies and nearly as many universities are studying the problem. There are several types of generators studied, but so far, none has demonstrated that the concept is economically viable.The variety of systems being studied is reminiscent of early aviation, because many kinds of different concepts were tested. It took about 50 years of development of prototypes between 1870 and 1910 for the principle of operation of aircraft got standardized around one that is still used today. During this period, a large number of concepts have been tested and many mistakes have made ​​on the model design, the experimental techniques and on the management of the project.The nowadays studied kite power systems tries to answer to the same specifications by around twenty different ways. This suggests that the concept of power generation has not yet found an optimal principle of functioning and that it is only at a phase of concepts exploration.The recent surge of kite power systems reminds of the early days of aviation. We sought to understand the mistakes that were made ​​during the early days of aviation to try to understand the mistakes that could be made with modern kite power systems.This study has set some guidelines that were used for developing the prototypes built during thesis .A wind tunnel was built for testing in simplified environments several models of kites. Several objectives were achieved during the thesis, including the control of the power generated by a kite flying in the presence of wind gusts and the study of a flight plan allowing the kite to stay in flight without wind and without the use of embedded energy.A total of 13 prototypes were developed during this thesis, a patent is being filed and a company using the results of the thesis is being created.
