ROCKET ENGINE Meaning and
Definition
-
A rocket engine refers to a device designed to generate thrust by expelling gas or other reactive materials at a high velocity. It is a type of jet engine that operates on the principle of action and reaction, in line with Newton's third law of motion. Rocket engines are primarily used in aerospace applications, such as to propel space vehicles, missiles, and satellites.
The engine typically involves the combustion of a propellant mixture composed of fuel and an oxidizer. The propellant undergoes a chemical reaction within the combustion chamber, producing a large volume of high-pressure exhaust gases. These gases are expelled with tremendous force through a nozzle at the rear of the engine, propelling the vehicle forward.
Rocket engines can be classified into different types based on their propellant, combustion process, and exhaust velocity. Some common types include liquid propellant rockets, solid propellant rockets, hybrid rockets, and electric propulsion engines. Each type has its own advantages and limitations, depending on the specific application and performance requirements.
Rocket engines operate in the vacuum of space, where there is no air to aid in the combustion process. Thus, they are completely self-contained and do not rely on atmospheric oxygen for the propulsion process, unlike conventional jet engines. This independence from atmospheric conditions allows rocket engines to operate effectively in space and is a significant factor in their widespread use for space exploration and satellite deployment.

Etymology of ROCKET ENGINE
The word "rocket" comes from the Italian word "rocchetto", meaning "a bobbin or spindle". This term was used to describe firework-like devices that were launched into the air, and eventually, it was applied to early forms of self-propelled devices as well. The word "engine" originally comes from the Latin word "ingenium", which means "an innate quality, talent, or natural disposition". Over time, "engine" came to refer to machines or devices that convert energy into useful work. Therefore, the term "rocket engine" combines the concept of a self-propelled device (rocket) with the connotation of a machine or device (engine).
