Jeturi

Jeturi is a term used primarily in speculative fiction to denote a hypothetical propulsion concept or class of spacecraft. It is not an established term in current aerospace engineering or physics.

In many works, jeturi devices are described as compact, high-energy systems that generate thrust without ejecting conventional propellant, often by manipulating exotic fields or spacetime. Depictions vary, but common motifs include rapid maneuverability, minimal exhaust signatures, and the use of advanced materials to withstand intense energy flux. In some narratives, jeturi propulsion challenges traditional ideas of momentum conservation or relies on speculative physics that has not been demonstrated in the real world.

Origin and usage: The term appears to be a coinage of contemporary speculative fiction and has not coalesced into a standardized concept in any real scientific literature. As a result, descriptions of jeturi propulsion differ widely between works. In world-building contexts, authors may define its properties to suit their plot, creating plausible-looking but fictional physics.
