Propulsion means the action or process of pushing or pulling to drive an object .
The term is derived from two Latin words: pro, meaning before or forward; and pellere, meaning to drive.
A propulsion system consists of a source of mechanical power, and a propulsor (means of converting this power into propulsive force).
Generation of the Propulsive Force
It is important to understand how propulsive force is calculated.
Propulsive Force = Mass Ejected per Unit Time x Effective Exhaust Velocity
To begin with rocket propulsion we share this video with you:
Which can let you understand how the Newton’s 3rd Law and the propulsion systems are related.
There are several types of rocket propulsion systems.
- Electric based
- Nuclear Energy Based
- Chemicals
- 3 types: Liquid , Solid and Hybrids
- Cold Gas
Now we share schematics for some types.
