METHOD FOR IMPROVED PRESERVATION OF THIN-WALLED SHELL- TYPE STRUCTURES IN PROLONGED STORAGE Russian patent published in 1994 - IPC

FIELD: transport. SUBSTANCE: before arrangement of structure on support, coefficients of long-term strength α, b and g of material of structure are determined experimentally, structure loading time is fixed in storage, and level of static equivalent tension of structure 1 is determined by means of transducers 11. Value is determined by formula given in invention description. Upon reaching the permissible value of the given value, command is given for engaging drives 10 which give rotary motion through driving gears 9, gear rings 8 supports 2 and 3 with the help of outer races and rollers to inner races rigidly connected with structure 1. As a result, structure 1 turns relative to base 4. When angle of 180 deg. is reached, drives are automatically disengaged. EFFECT: more rational utilization of strength reserve of structure. 2 dwg
