Magnetic veil

It is about a proposal for a mode of space Propulsion which makes use of a Magnetic field to deviate of the Particule S charged electrically, moving (typically, those of the Solar wind).

Principle and analogies

This concept presents points commun run with the ionic Moteur: in both cases, it is a question of modifying the kinetic Moment of a gas of Ions or plasma (one regards the Proton S of the Solar wind as hydrogen ions). One exerts in return an influence on the movement of the Spaceship. The behavior of a Fluid conducting of the electric current in the presence of electromagnetic fields, concerns the Magnétohydrodynamique.

Strong points and weaknesses

The theoretical main advantage lies in the weight saving. For the conventional engines, it is necessary to embark the mass to be ejected and energy to eject it. With a traditional ionic engine, only the mass to be ejected is embarked, the energy of the ejection can be taken on the spot with solar panels or come from a thermoelectric generating with radioisotope. The solar sail is freed from this last burden, since it draws the ions to be ejected in its immediate environment.

Such a device can also be useful in any magnetic field even stripped of plasma, for example the magnetosphere of a planet.

In both cases, not requiring more fuel, the spaceship thus becomes lighter easier to send in space, at a less cost. Moreover, its autonomy of displacement corresponds then to that of its electric energy source. In the case of a thermoelectric generating with radioisotope it can exceed the twenty years!

However, as the solar sail or the ionic engine, this system delivers only one weak force of propulsion, though over great durations of time.

Moreover it acts for the moment only of one concept theoretical which will undoubtedly require many tests before becoming an effective device
