COMBINED HIGH-PRESSURE BOTTLE Russian patent published in 1997 - IPC

FIELD: high-pressure bottles. SUBSTANCE: combined high-pressure bottle contains hermetic cylindrical envelope provided with hemispherical or elliptical bottoms with pole bosses. Rings made from fibrous composite material are laid on surface of each bottom tightly to each other and coaxially relative to cylindrical envelope. Longitudinal framework of load-bearing envelope made from "n" pairs of closed members is located on surface of cylindrical envelope. Each closed member made from bundles of fibrous composite material consists of two parallel sections whose ends are conjugated in pairs by means of curvilinear sections. Rectilinear sections of each pair of closed members are located tightly to each other on surface of cylindrical envelope in parallel with its axis and symmetrically relative to respective diametrical plane. Curvilinear sections of each adjacent pair of closed members are located above rings on different sides relative to bosses and are get in contact with them in diametrically opposite points. Upper layer of load-bearing envelope is located above cylindrical section of longitudinal framework; upper layer of load-bearing envelope is formed by outer winding of fibrous composite material. EFFECT: enhanced reliability. 2 dwg
