ROCKET PROPULSIONS Meaning and
Definition
-
Rocket propulsion refers to the mechanism by which a rocket is propelled through the use of high-speed gas ejection. It involves the expulsion of gases at high velocities in the opposite direction to achieve forward motion. This process is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Typically, rocket propulsion systems work by burning a propellant mixture inside a combustion chamber. The combustion produces an intense release of energy, leading to the formation of high-pressure and high-temperature gases. These gases expand rapidly and escape through a nozzle at the rear of the rocket. As the gases are expelled, they impart a powerful thrust to the rocket, propelling it forward.
Rocket propulsion can be achieved through various mechanisms, including solid, liquid, and hybrid propellant systems. Solid rocket motors contain a mixture of fuel and oxidizer that are chemically combined and packed into a solid form. When ignited, the solid propellant undergoes a self-sustaining combustion process.
Liquid rocket engines, on the other hand, use separate liquid fuels and oxidizers that are stored in separate tanks and mixed together in a combustion chamber to generate thrust. The propellants can be ignited by various means, such as hypergolic ignition or spark ignition.
Hybrid rocket engines combine elements of both solid and liquid propellant systems. They utilize a solid fuel grain while introducing a liquid or gaseous oxidizer into the combustion chamber to burn with the solid fuel.
Overall, rocket propulsion is a fundamental concept in aerospace and space exploration, enabling the launch and maneuvering of rockets and spacecraft to overcome Earth's gravitational pull and travel through space.

Etymology of ROCKET PROPULSIONS
The term "rocket propulsion" originated from the word "rocket", which is derived from the Italian word "rocchetta" meaning "distaff" (a tool used in spinning). "Rocchetta" itself comes from the Latin word "rota" meaning "wheel". The resemblance of early rockets to a spinning wheel led to the association with "rocchetta". Over time, "rocket" specifically came to refer to self-propelled devices, departing from its original association with spinning tools. "Propulsion" is derived from the Latin word "propulsus", which means "driven forward". Thus, the etymology of "rocket propulsion" is deeply rooted in both Italian and Latin languages, with "rocket" representing the device itself and "propulsion" denoting the act of driving or propelling it forward.
