Impellorista

Impellorista is a neologism used to describe a person who studies, designs, or advocates impeller-based propulsion and energy transfer devices. The term combines impeller, the rotating component in pumps and turbines, with the suffix -ista, a productive agent suffix found in several languages, giving a sense of a practitioner or enthusiast. Although not an established professional title, impellorista appears in online discussions, maker culture, and speculative design contexts to label individuals focused on impeller technology.

In engineering usage, impelloristas examine blade geometry, clearance, materials, and manufacturing methods to maximize pressure, flow, and efficiency while minimizing cavitation and wear. They may work on axial-flow or radial-flow impellers, pumps for fluids, turbomachinery, or compact propulsion concepts for drones, underwater vehicles, and microfluidic systems. In theoretical or science-fiction settings, impellorista characters or movements are depicted as proponents of impeller-driven propulsion as a core principle, exploring the implications for energy transfer, control, and system integration.

There is no standardized certification or body of work specifically for impelloristas, and the term is largely colloquial. Related topics include pump engineering, turbomachinery, impeller design, and fluid dynamics.
