FUEL TANK OF SPACECRAFT INSTALLATION Russian patent published in 2018 - IPC B64G1/40 

FIELD: astronautics.

SUBSTANCE: invention relates to the space equipment. Fuel tank of the propulsion system (PS) of the spacecraft (SC) contains a body formed by hermetically connected hemispheres with fittings for connection of gas lines and flanges for securing fuel lines, a displacer disposed within the housing and having an elastic shell fixed inside the tank body, the carcass of which has stiffeners. Displacer is made of two identical parts attached to the joint of the hemispheres under the elastic sheath, each of which is made in the form of a diaphragm element of circular shape, the center of which coincides with the center of the displacer, and the diaphragm belts from the material with the thermomechanical shape memory effect, connecting belts, located in the same plane with diaphragm belts from the same type of connectors, the longitudinal axes of which are uniformly located along the rays emerging from the center of the diaphragm element. Connectors of the first belt are located between the diaphragm element and the first diaphragm belt, and the connectors of the other belts are attached to the corresponding diaphragm belts and the fixing disk at the end of the hemisphere.

EFFECT: reduced mass of the remote control and increased survivability thereof.
