Today, September 8, 2021, on the East spacecraft started refueling the Overclocking block “Frigate”.
In accordance with a comprehensive graph of training, the joint calculation of the South Space Center specialists (a branch of the center of exploitation of land-based space infrastructure facilities) and the Scientific and Production Association named after S.A. Lavochkina (both enter the perimeter of Roskosmos state corporation) started refueling fuel components and compressed gases of the frigate acceleration unit, designed to implement the 49th mission to launch ONEWeb spacecraft.
Complete all operations on the refueling planned by September 29, 2021. After that, the acceleration unit will be transported to the installation and test case of spacecraft for carrying out work on the assembly of the cosmic head.
The universal acceleration unit “Frigate” was created in the NGO of Lavochkina and is intended for use in the composition of medium and heavy class missiles in order to remove spacecraft to various set orbits. The basis of the structural-layout circuit of the acceleration unit is the tank block, built on a monoblock carrier scheme. It has a torusferic configuration consisting of six spherical tanks, separated by spherical bottoms. Four of them are the pots of oxidizing agent and fuel, two tanks are compartments for the placement of onboard devices and equipment.
