METHOD OF MANUFACTURE OF HOLLOW BEARING-WALL SKELETON STRUCTURES Russian patent published in 1995 - IPC

Abstract RU 2030336 C1

FIELD: manufacture of flying vehicles. SUBSTANCE: the article being formed is placed in press mould 9 and its forming is effected inside press mould with the aid of solid mandrels of simplified construction coated with tight elastomer envelopes 11 which press members 23 made of elastomer material and act on them under action of pressure air fed to mandrels. Members 23 which take up pressure of tight envelope take part immediately in forming the three-dimensional article of optimal skeleton structure. In feeding the pressure air to press mould, it is simultaneously heated to required moulding temperature. EFFECT: improved quality of structure. 2 cl, 8 dwg
