SPACECRAFT FUEL TANK FOR LIQUID COMPONENTS STORING AND DELIVERY

摘要

FIELD: transport.SUBSTANCE: invention relates to pneumohydraulic system for fuel components delivery to jet propulsion system of aircraft. The fuel tank includes pressurised body made of two semispheres with input and output nozzles and external mounting elements. Metal diaphragm is placed inside the body and connected with them along perimeter. Its thickness is maximal in equatorial part and gradually decreases towards polar part. In this system, the diaphragm in its equatorial part (6) is made in the form of truncated cone, in its middle part (7) - in the form of toroidal surface, and in the polar part (8) - in the form of spherical surface segment. The final (after re-laying) position of the diaphragm is shown on the drawing by dotted line.EFFECT: better performance of metal diaphragm due to lowered loads and deformations of the diaphragm in places of its fixation to tank body.2 cl, 3 dwg
