On the Baikonur cosmodrome in line with a comprehensive schedule of work on the ONEWEB spacecraft launch program within the framework of Mission No. 36, the preparation of the Frigate acceleration unit is continuing.
Currently, it was transported from the installation and test case of the site No. 31 to the site No. 112. The next stage of preparation is the movement of the “frigate” in the gateway chamber. Specialists of the South Sports Center (branch of the center of exploitation of landflowing infrastructure) and the Scientific and Production Association of the name of SA participated in these works Lavochkina (enter the perimeter of the state corporation “Roskosmos”).
Start of the Soyuz-2.1b media missile with an overclocking unit “Frigate” and 34 satellite spacecraft of the OneWeb company scheduled on September 14, 2021 from the starting complex “East” of the Baikonur cosmodrome. ONEWEB satellites are designed to create a space communication system that provides high-speed Internet access at any point of the planet. The orbital group will consist of 18 planes of 36 devices in each.
Universal accelerated block “Frigate” was created in NGOs Lavochkina and is intended for use as part of medium and heavy class missiles in order to remove spacecraft to various set orbits.
The basis of the structural-layout diagram of the acceleration unit is a block of tanks constructed by a monoblock support 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.
In one of the containers there is a monoblock of the control system, including satellite navigation equipment and thermal mode fans, in another – small dashboard, service blocks, as well as high pressure switches for high-pressure motor installation and motor stabilization, orientation and launch .
