Lançador

Lançador is a term used to describe a device or system that initiates or releases something, ranging from physical projectiles to software actions. In a broad sense, it refers to equipment or programs designed to put a payload or function into motion or deployment.

In military and technical contexts, a lançador (or launcher) is commonly a mechanism that stores, loads, and releases ammunition such as grenades or rockets. These systems can be handheld, mounted on firearms, vehicles, ships, or fixed emplacements. They may be designed for guided or unguided projectiles and vary widely in size, range, and propulsion method.

In aerospace and space exploration, a veículo lançador or lançador espacial is a rocket-powered system capable of delivering payloads—such as satellites or scientific instruments—from Earth into space. Launch vehicles are typically multi-stage and may involve boosters and upper stages to achieve the required velocity and altitude.

In computing and consumer electronics, a lançador is a software interface or program that starts other applications. Launcher programs present icons or widgets to launch tools, organize access to frequently used software, and sometimes customize the user experience. In many mobile and desktop environments, the launcher defines the home screen arrangement and the method for accessing installed apps.

Etymology: the word derives from lançar, meaning to throw or send forth. Across domains, the concept of a lançador is tied to initiating motion, deployment, or activation of a tool, system, or program.
