Field propulsion : ウィキペディア英語版 | Field propulsion
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. Some methods such as the gravity assist have been in use for interplanetary spacecraft missions for decades. Others are speculative and have not yet been demonstrated to be of practical use or theoretically valid. == Types ==
