| Zusammenfassung |
| The electric solar wind sail (E-sail) is a new type of propellantless
propulsion system for Solar System transportation, which uses the natural
solar wind to produce spacecraft propulsion. The E-sail consists
of thin centrifugally stretched tethers that are kept charged by an onboard
electron gun and, as such, experience Coulomb drag through the high-speed
solar wind plasma stream. This paper discusses a mass breakdown and a
performance model for an E-sail spacecraft that hosts a
mission-specific payload of prescribed mass. In particular, the
model is able to estimate the total spacecraft mass and its propulsive
acceleration as a function of various design parameters such as the
number of tethers and their length. A number of subsystem masses are
calculated assuming existing or near-term E-sail technology. In light of the
obtained performance estimates, an E-sail represents a promising propulsion
system for a variety of transportation needs in the Solar System. |
