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 field, which can then be repelled.

2024年2月27日 · Electromagnetic propulsion, however, converts electric power, potentially from nuclear sources, into thrust without the need for massive fuel reserves, offering longer missions with less mass. What challenges must be overcome to make electromagnetic propulsion viable for manned spaceflight?

2023年10月22日 · Florian Neukart introduces the Magnetic Fusion Plasma Drive, a revolutionary propulsion method combining fusion and ionic techniques. Offering immense energy density and numerous advantages, it could redefine space exploration, although challenges in sustaining fusion reactions in space remain.

A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics. The fluid is directed to the rear and as a reaction, the vehicle accelerates forward. [1][2]

2024年1月8日 · Magnetic propulsion in aerospace refers to the use of magnetic fields to propel spacecraft without traditional fuel. By harnessing electromagnetic forces, this technology has the potential to revolutionize space travel by enabling fuel-less propulsion systems.

2023年5月24日 · The US Defense Advances Research Projects Agency (DARPA) have announced a 42 month programme to develop develop a maritime propulsion system, a magnetohydrodynamic (MHD) drive, that uses no moving parts, silently propelling ships and boats with magnets and an electric current.

2016年11月19日 · In case you've missed the hype, the EM Drive, or Electromagnetic Drive, is a propulsion system first proposed by British inventor Roger Shawyer back in 1999. Instead of using heavy, inefficient rocket fuel, it bounces microwaves back and forth inside a cone-shaped metal cavity to generate thrust.

2005年1月1日 · The principles of the magnetic propulsion (Prog Aerospace Sci 2001;37:245–61) allow to substantiate the proposed application and variant of design of the magnetic flight vehicle, to clarify its advantageous properties and to determine the main problems to …

2005年1月1日 · Electromagnetic propulsion [1,3], or magnetic propulsion [2,6], is a conceptual means of accelerating an object via the interaction of external magnetic field and a local magnetic field generated by an electric current.

In MagLev trains, electromagnetic propulsion works thanks to a linear motor. The train track pushes away the train’s electromagnets, forcing it forward. But how would that work in space? An engineer named Roger Shawyer believes electromagnetic propulsion can also be …
