Autorotation of CONEX underslung load

Abstract

[EN] The CONEX (Container Express) is a military shipping container, therefore only some elaborate and expensive researches ful lled by the U.S. have been done. They provided data about the behaviour of the CONEX when it is autorotating, but they are very costly and complex. Also, they have focused on the nal steady-state condition and they have not taken into consideration the start-up process. The main objective of this project is the understanding of the CONEX autorotation. In order to understand this behaviour of the underslung loads, the rst step of this study is review several documents explaining autorotation, aerodynamics of square structure, spinning, CONEX, wind tunnel and more concepts of interest to understand the behaviour of the container when it starts to autorotate.
