Electromagnetic propulsion (EMP), is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The electrical current is used to either create an opposing magnetic field, or to charge a fluid, which can then be repelled. It is well known that when a current flows through a conductor in a magnetic field, an electromagnetic force known as a Lorentz force, pushes the conductor in a direction perpendicular to the conductor and the magnetic field. This repulsing force is what causes propulsion in a system designed to take advantage of the phenomenon. The term electromagnetic propulsion (EMP) can be described by its individual components: electromagnetic- using electricity to create a magnetic field (electromagnetism), and propulsion- the process of propelling something. One key difference between EMP and propulsion achieved by electric motors is that the electrical energy used for EMP is not used to produce rotational energy for motion; though both use magnetic fields and a flowing electrical current.

Electromagnetic propulsion is utilized in transportation systems to minimize friction and maximize speed over long distances. Power aircraft by magnetic currents.

There are multiple applications for EMP technologies in the field of aerospace. Many of these applications are conceptual as of now, however, there are also several applications that range from near term to next century. One of these particular systems is based on the direct interactions of the vehicle's own electromagnetic field and the magnetic field of the earth. The thrust force may be thought of as an electrodynamic force of interaction of the electric current inside its conductors with the applied natural field of the earth. To attain a greater force of interaction, the magnetic field must be propogated further from the flight craft. The advantages of such systems is the very precise and instantaneous control over the thrust force. In addition, the expected electrical efficiencies are far greater than those of current chemical rockets that attain propulsion through the intermediate use of heat; this results in low efficiencies and large amounts of gaseous pollutants. The electrical energy in the coil of the EMP system is translated to potential and kinetic energy through direct energy conversion. This results in the system having the same high efficiencies as other electrical machines while excluding the ejection of any substance into the environment.

The current thrust-to mass ratios of these systems are relatively low. Nevertheless, since they do not require propulsive mass, the vehicle mass is constant. Also, the thrust can be continuous with relatively low electric consumption. The biggest limitation would be mainly the electrical conductance of materials to produce the necessary values of the current in the propulsion system.Most of these kinds of propulsion work by electrically powering propellant to high speed. Electric thrusters typically offer much higher specific impulse, however, due to practical power source constraints thrust is weaker compared to chemical thrusters by several orders of magnitude.This type of rocket-like reaction engine uses electric energy to obtain thrust from propellant carried with the vehicle. Unlike rocket engines, these kinds of engines do not necessarily have rocket nozzles, and thus many types are not considered true rockets. Electric propulsion thrusters for spacecraft are usually grouped in three families based on the type of force used to accelerate the ions of the plasma:If the acceleration is caused mainly by the Coulomb Force (i.e application of a static electric field in the direction of the acceleration) the device is considered electrostatic

The electrothermal category groups the devices where electromagnetic fields are used to generate a plasma to increase the heat of the bulk propellant. The thermal energy imparted to the propellant gas is then converted into kinetic energy by a nozzle of either solid material or magnetic fields. Low molecular weight gases are preferred propellants for this kind of system.

Performance of electrothermal systems in terms of specific impulse is somewhat modest (500 to ~1000 seconds), but exceeds that of cold gas thrusters, monopropellant rockets, and even most bipropellant rockets

  • I came here to get information on new forms of propulsion not read bullshit from supremacist idiots who don't know how the world really works.

  • @marlboroman67213 - the Hg aspect is from Vimana design, that's where the Nazis got some of theirs from too - Aryan, Indo European, Vedas.

  • The Nazi-German technology was stolen by US goverment.... Apollo rockets were created by the V-2 rocket scientist, also the cruise missile came from the "buzz bomb" and the "H-bomb was designed by Germans. Hitler prevailed thru American goverment........
