Roscosmos announced the completion of the fourth stage of comprehensive testing of the universal technical complex of the Angara rocket at the Vostochny Cosmodrome. This stage included laying the rocket blocks called Angara-NZ on technological farms for storage in a warehouse.
According to the state corporation, in the future "the mock-up will be used for comprehensive tests for the manned program."
Earlier in mid-August, it became known that Russia had begun mass production of Angara launch vehicles. To develop the Russian space program, at least eight of them need to be produced per year.
Angara-NZ
A special electric refueling ground-based liquid mock-up of the Angara rocket in full size and with the same mass as the original. This is a complete copy of the Russian Angara-A5 rocket.
It was on it that all actions for pre-flight checks of the first heavy Angara-A5 were worked out at Vostochny: from delivery to the cosmodrome to autonomous and comprehensive tests, assembly into a "package", removal to the launch complex, installation at the testing stages on the launch table.
This is how Russia decided to avoid risks when carrying out all important procedures only with the flight version of the rocket. For the Angara family, a separate launch complex was built from scratch in five years at Vostochny, which was tested using Angara-NZ. Following the tests, the launch and certification of the Amur space rocket complex at the Vostochny Cosmodrome were successful.
The overall mass mock-up was created by specialists from the M.V. Khrunichev State Space Scientific and Production Center. All systems that participate in refueling and preparation at the launch complex are made fully functional in Angara-NZ.
That is, before sending the Russian heavy Angara A-5 rocket on its first flight, not only, for example, electrical tests, but also full refueling with liquid oxygen and naphthyl were worked out on the mock-up.
