What is PROPULSION?

I wrote about Kaveri engine in detail in my previous blogs. Now i would like to start with some basics of propulsion.

My wish is to write pertaining propulsion, so, let us see what propulsion actually means...

Propulsion means to move any body in some direction with aid of some force.

Propulsion is defines as "the act of propelling, the state of being propelled, a propelling force or impulse" and defines the verb propel as "to drive, or cause to move forward or onward".

From the above definitions we can say that propulsion includes the study of propelling force, the motion caused and the bodies involved.Propulsion involves a body to be propelled and more than one additional bodies, called the propellant.
