Language: Russian

Annotation: The paper addresses a new, authors- developed method of mass optimization of rocket bays of wafer structure bearing during operation on locally disposed parking supports. The method allows, due to more rational distribution of materials in the structure in accordance with acting load, decreasing the mass of bays by up to 20%.

Language: Russian

Annotation: The paper considers the TZS-U design developed by Yuzhnoye SDO specialists for windward part of reusable spacecraft with external metal three-layer panel, U-like joint and tiled thermal protection, in which the problem is solved of compensation of thermal expansions and sealing of gaps; for optimization of structural mass. The specially created dispersion-hardened powder alloy based on nichrome and aluminum with yttrium dioxide with decreased specific mass of 7500 kg/m3 and lighter felt of MKRF brand are used , and honeycomb filler of three-layer panel is replaced by the filler with square cell.
