Functional Cargo Block
The Functional Cargo Block or FGB (from the Russian "Функционально-грузовой блок", ФГБ, "Funktsionalno-gruzovoy blok", FGB,
Following the development of the FGB for the TKS spacecraft, the FGB (without VA spacecraft) formed the basis for space station modules in the Soviet and Russian space program – these space station modules are to some extent called Functional Cargo Block (FGB) as well, like the Zarya FGB module.[1][2]
The FGB provides "functional" support in the form of electrical power, propulsion, guidance and docking; The support for "cargo" operations is supplied in the form of a pressurized habitable cargo storage section (accessible by the crew) and the externally mounted fuel tanks.
History
The Functional Cargo Block (FGB) was originally developed as support for the
Design
The basic layout of the exemplary Zarya FGB consists of two sections:[4]
- The Instrumentation and Cargo Compartment (ICC) with a pressurized volume of 64.5 cubic metres (2,280 cu ft)
- The Pressurized Adapter (PA) with a pressurized volume of 7.0 cubic metres (250 cu ft)
The PA is separated from the ICC by a spherical bulkhead containing an 800 mm hatch. Both pressurized sections contain working and living areas, in addition to instrumentation separated by interior panels.
