Advantages of Biliquid Propellants over Solid Propellants
1. The biliquid propellants generate higher thrust as compared to solid propellants.
2. The thrust produced by liquid propellants can be controlled by switching on and off the flow of propellants. On the other case, the thrust should not be controlled in solid propellants.
