New approach for design and development of multi-role aerial modulefor management of the pedological drought

Soil drought, seen as the depletion of soil water reserves at watering depths below the readily accessible water content, is a challenging problem for humanity, with a massive negative impact on social, economic, and environmental activities. This paper proposes a new approach to the management of soil-induced drought disasters. In this respect, 8 variants of fabrics (used as matrices of composite materials) and 3 variants of composite structures, used in the construction of collapsible multi-roll aerial modules for soil drought, have been developed and tested in INCDTP-accredited laboratories. Thus, the structures have been tested in terms of tensile behaviour, the strength and elongation at break, respectively the strength and elongation at tear. The experiments carried out, as well as the experience of specialists in the design of technical textile structures for special applications, have shown that the manufacturing of textile supports used as matrices for composite materials used in the construction of collapsible multi- roll aerial modules for pedological drought, structures specific to textile articles with special uses are used, for which programming schemes have been obtained. The particularly restrictive conditions imposed by the field of use, in conjunction with the values obtained from the physical-mechanical testing of composite fabrics and structures, required the use of specialised software to obtain digital solutions. The results obtained as a result of FEM simulation predicted the behaviour of textile structures, composites, and the air module under dynamic conditions.
