37th ESA Antenna Workshop on large deployable antennas, ESA/ESTEK,ESA-ESTEC, Noordwik, The Netherlands201615/11-17/11European Space AgencyThe ideology for the creation of large size reflector autonomous complexoral

The existing and possible versions for the interaction and merger of large unfolding antennas and space crafts are reviewed  within  this  thesis.  The  prognosis  for  the difficulties connected with the creation of unified space complex while using the reflectors with large aperture is discussed as well. Therein, one of the main factors is the issue of stabilization and management  of the large size reflector antenna or the antennas connected to the space craft. This is mainly caused by the increase of distance from the center of gravity of the complex from the space craft on the space complex.                                                                                                                         The idea for the merging of space craft and reflector antenna complex, after which the unified space autonomous complex is constructed  on the base of the large autonomous reflector is also reviewed within the current  thesis.  One  of  the  conditions  of the  above mentioned complex is the existence of extensor and other powerful  elements  on which  the  separate  block  and elements will be placed. In other cases the reflector antenna  shall  have  the  powerful  fields  where  the powerful factors will be concentrated.

National Accelerated Bridge Construction ConferenceUSA Miami, Florida.2017 December 7 - 82017 National ABC ConferenceFolding metal bridge with falcate modules – KM 02Toral

Practically, today in Georgia there is no inventory tools and capabilities to rapidly and eff ectively reconstruct destroyed means of transport and communications. In connection with this, elaboration and manufacturing of rapidly deployable bridges for the use in extreme conditions are very important for our country. Additionally, such bridge may eff ectively be used in country defense purpose and also to transfer specialists and assembling equipment to rapidly recover damaged electrictransmitting wires and towers in those areas where the road network is underdeveloped and there are no bridges over ravines and mountain streams. Here we describe the structure of deployable metal bridge KM02T. It can be used to overcome an obstacle of 4-5.5 meter depth.

In deployable space reflectors, especially in the latest period, there are widespread ring structures. Its main characteristic is support, power ring, which spreading and shape fixation of deployed condition provides creation of the whole structure of reflector. So attempts are natural, to create a folding ring structure that will satisfy all the requirements and will be universal for erecting any reflector. Such approach is not probably entirely justified. Depending on the reflectors 'parameters- maximum dimension of the aperture, plans, focal length and other constructive and technological requirements are the advantages of different types of structures for different reflectors. For this purpose, new types of structures have recently been proposed in Georgia. Reflectors' parameters constructive peculiarities and technological processes are recommended for different groups of reflectors. They are divided and discussed according to the following structure- frame, girder and combined structures
