Functional Cargo Block
The Functional Cargo Block or FGB (from the Russian "Функционально-грузовой блок", [Funktsionalno-gruzovoy blok] Error: {{Lang}}: text has italic markup (help) or ФГБ) is a type of space-station module. It provides electrical power, propulsion, guidance and storage, both inside the pressurized section and in the externally mounted fuel tanks. It is a descendant of the TKS spacecraft designed for the Russian Salyut program.
FGB consists of the Instrumentation and Cargo Compartment (ICC) and the Pressurized Adapter (PA) designed to accommodate onboard systems supporting docking with a station or visiting spacecraft. PA is separated from the ICC by a spherical bulkhead which has an 800 mm manhole. The internal volume of the ICC and PA is divided into two areas: instrumentation area and living area.[1]
FGB based spacecraft include:
- Polyus spacecraft[2]
- Kvant-1 (Mir module)
- Kvant-2 (Mir module)
- Kristall (Mir module)
- Spektr (Mir module)
- Priroda (Mir module)
- Zarya (ISS module)
- Nauka (ISS module)
