[FPSPACE] Soyuz LV question

[Nicolas PILLET]

Dear FPspacers,

I have a question regarding the Blocks B/V/G/D/ attachment to the central core (Block A).

Lateral blocks litterally bear the central core. During the ascent, they litterally PUSH the launcher, so if their RD-107 engines shut down, they simply fall down on the pad, like it was the case during Foton-M n°1 launch, in october 2002.

I am writing an article on the lateral blocks for my website, Kosmonavtika, and you can see the draft here :

My question is : do you know how the separation occur after the completion of the lateral blocks' burn ? Do they NATURALLY fall down, or is there a separation device to ensure they separate exactly at the good time ?

Other question : how are the lateral blocks linked to the pad's "arms" ? And how are the "arms" separated at the moment of the launch ?

Thank you very much for sharing information !

Regards,

Nicolas
