Field propulsion is the concept of spacecraft propulsion where no propellant is necessary but instead momentum of the spacecraft is changed by an interaction of the spacecraft with external force fields, such as gravitational and magnetic fields from stars and planets. It is purely speculative and has not yet been demonstrated to be of practical use, or theoretically valid.

  • Propulsión por efecto de campo o propulsión de campo, es el concepto de propulsión espacial donde ningún propulsor es necesario pero en cambio, el ímpetu de la astronave es cambiado por una interacción de la nave espacial con campos de fuerza externos, como campos gravitacionales y magnéticos de estrellas y planetas. Es puramente especulativo y no ha sido todavía demostrado para ser de uso práctico o teóricamente válido. (es)

  • 无工质型发动机(英語:propellantless drive),即无需火箭推进剂的发动机。有别于传统的需要喷射工质的发动机,无工质型发动机是不需要工作物质的。工质即工作物质,传统的工质型发动机(火箭和喷气式飞机)是依据动量守恒定律,靠燃料燃烧向后喷射工质来实现推进的。无工质发动机则相反。 (zh)
