Main structure of the SLV propulsion system.

Main structure	Material	Function
Liquid oxidizer	98% H2O2	Provide chemical energy
Solid fuel	HTPB-based grain	Provide chemical energy
Gas bottle	CF wound aluminum liner	Contain pressurization gas
Oxidizer tank	CF wound aluminum liner and oxidizer sac	Contain liquid oxidizer
Chamber and nozzle	CF wound shell and high-silica insulation	Contain fuel grain and high-pressure burn gas
Valves and tubes	Mainly aluminum alloy	Feed liquid propellant
Catalyst bed	Stainless-steel shell and silver mesh	Decompose H2O2
Turbopump	Details refer to Reference [20]	Increase the pressure of oxidizer
Thrust vector control actuator	Given by experience	Control the thrust vector direction
