Definition of thruster

The word "thruster" can be traced back to the mid-1960s, mainly in the field of aerospace engineering. It refers to an engine or mechanism designed to provide thrust, or propulsive force, necessary for movement or maneuvering. The term comes from the noun "thrust," which stems from the Old English word "thryssan," meaning "push" or "shove." The word "thruster" specifically refers to the type of engine or device used to generate thrust, as opposed to generic terms such as "propulsor" or "engine." In aerospace applications, thrusters are often used in conjunction with other propulsion systems, such as reaction control systems and main engines, to amplify or supplement their performance. Their compact size and high acceleration capabilities also make them useful in various other industries, from marine propulsion to robotic systems demanding precise movements. In summary, the word "thruster" can be categorized as a technical term in the field of propulsion technology, derived from the verb "to thrust" and used to describe engine types that generate propulsive force.
