What mechanical components are utilized to achieve the clean separation of the Soyuz strap-on boosters?
Answer
Explosive bolts and pneumatic pushers
The successful and synchronized separation of the four strap-on boosters from the core stage relies on a complex, choreographed mechanical sequence designed for reliability. This process involves the use of explosive bolts, which are used to sever the structural connections holding the boosters in place. Simultaneously, pneumatic pushers are employed to provide the necessary physical impulse to ensure the boosters move away cleanly from the core stage immediately after the bolts fire, preventing any interference that could compromise the ascent trajectory.
