Information × Registration Number 0121U110119, ( 0223U004039  ) R & D request Title Development of a method for predicting the life of composite structures aerospace technology throughout the life cycle Head Bobyr Mykola I., Доктор технічних наук Registration Date 27-03-2021 Organization National Technscal University of Ukraine "Kiev Polytechnic Institute". popup.description1 To research the thermal-forces load of the main types of power elements of aerospace technology, which are made of PCM, and to develop methods for assessing its impact on the kinetics of accumulation of scattered fracture in stress concentration zones. To develop an effective method of designing these power elements, taking into account the degradation of physical and mechanical properties of PCM during the life cycle of a dual-use product. To determine the main characteristics of PCM products obtained by additive processes and to offer alternative technologies for the manufacture of non-bearing systems of aerospace vehicles (multiplane housings). To carry out mechanical tests of such systems, to estimate degradation of the used plastics (PLA-carbon and REEK) in operating conditions, to offer new principles of reproduction of axisymmetric products on the additive equipment equipped with original technical devices. Play axisymmetric shells (tanks) and test them for tightness and static pressure popup.nrat_date 2024-12-09 Close
