CLASSIFICATION SPACE PROPULSION SYSTEM

The space propulsion system is classified by the type of energy sourced used. in this blog, we will talk about the chemical space propulsion system. it is classified in two different types 1. solid 2. liquid 3. hybrid. Liquid space propulsion system is classified as 1. pressure fed,2. pump-fed, 3. bipropellant 4. monopropellant.

A propellant is a chemical substance used in the production of energy. The propellant consists of fuel+oxidizer+ additives (in a very less quantity). 

  SOLID PROPELLANT 

The solid propellant is in which fuel, oxidizer, additives all are in the solid phase.  

for example 

Sucrose+ KNo3 

(fuel)        (oxidizer)

SOLID PROPELLANT  IS CLASSIFIED INTO  

1.Homogenous (colloidal) propellant

• Single base propellant
• Double base propellant 
• Triple base propellant 

2.Non- homogenous (composite) propellant 

HYBRID PRPELLENT 

The hybrid propellant is in which fuel and oxidizer both are in a different phase.

for example 

  LIQUID PROPELLANT

The liquid propellant is in which fuel and oxidizer  both are in liquid form

for example 

liquid hydrogen (fuel)+liquid oxygen(oxidizer)

LIQUID PROPELLANT IS CLASSIFIED INTO 

1. mono-propellant

• simple
• composite 

2. Bi-propellant

• hypergolic
• non-hypergolic
