ABSTRACT:
In space exploration, an attitude control engine or a thruster may have an extended period, such as years, of inactivity prior to being required to complete a desired mission. The fuel for this mission is contained in a fuel tank for the same extended period of time and tends to corrode elastomeric components. To isolate the fuel from elastomeric components during the storage period, the fuel tank has a metallic shear seal. When actuated, a piston ruptures the shear seal and delivers the fuel to a power plant. A shear seal that is unitary with the inner walls of the fuel tank eliminates the need for an interfacial weld that may constitute a shear seal failure site.
