What are the advantages of liquid propellants over solid propellants?
• List the different techniques by which petroleum fuels are manufactured. • How are the liquid propellants usually classified?Ans.: They are usually classified as: a) Monoliquid Propellants In their propellants, only one chemical act as fuel as well as oxidizer. Eg: Hydrazine, Nitromethane. b) Biliquid Propellants In this propellant, there is liquid fuel and liquid oxidizer. Eg: Liquid Hydrogen and liquid oxygen. • Give the classification of liquid propellant on the basis of origin. • What parameter decides the behavior of propellant? Ans.: Specific impulse. Higher the specific impulse better is the propellant.
