Abstract: A turbine, for example a wind turbine, is equipped with a rotor (1) with a vertical axis and a screens system (31, 32) for conducting wind and fluid to the rotor. The turbine is equipped with a direction device (57) which produces a direction signal, and a way (55, 56) to direct the screens system (31, 32) depending on the direction signal. The rotor blades are fitted on the sides turned towards the axis with an open curl shape 34.

Abstract: An ultralight unit load device has a ruggedized quadrangular composite structure with a cellular load-bearing core sealed in successive ordered-polymer stiffening plies and trimmed at the outer edges with a hollow, multi-chambered profile of lightweight material fixed with a flush attachment member so as to present a flat surface for easy loading and unloading.
