Title: Propellants for space launch vehicles
Authors: Shanker, Kali
Issue Date: Dec-2008
Publisher: CSIR
Abstract: Propellants are chemical mixtures which are burned inside the rockets for producing thrust and this mixture consists of a fuel and an oxidizer. Fuel is that substance which, if combined with an oxygen producing gas (for propulsion) starts burning. Oxydiser is an agent that releases oxygen for combination with a fuel. The ratio of the oxidizer and the fuel is called mixture ratio. Propellants are classified according their states, namely liquid, solid or hybrid. The parameter by which the efficiency of a rocket is judged is called specific impulse. The specific impulse represents as to how many pounds (or kilograms) of thrust is generated by burning one pound (or one kilogram) propellant in one second. Specific impulse is the property of various propellants but its actual value, to some extent, goes on changing depending upon the design of rocket engine and the operating conditions.
