In 2008, a team of Chinese researchers led by Juan Yang (杨涓), professor of propulsion theory and engineering of aeronautics and astronautics at Northwestern Polytechnical University (NWPU) in Xi'an, China, said that they had developed a valid electro-magnetic theory behind a microwave resonant cavity thruster.
Plasma propulsion engines using magnetohydrodynamics for space exploration have also been actively studied as such electromagnetic propulsion offers high thrust and high specific impulse at the same time, and the propellant would last much longer than in chemical rockets. [14]
Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in orbit. [1] The propulsion system is controlled by power electronics.
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.
Former Space Systems Lab associate director Dr. Raymond Sedwick (now at the University of Maryland, College Park) has been awarded the first Bepi Colombo Prize for a paper on electromagnetic formation flight. According to Aero-Astro Professor Manuel Martinez-Sanchez, who worked with Colombo and was a juror in the competition, "The jury was ...
In chronological order, spacecraft are listed equipped with electric space propulsion. This includes both cruise engines and/or thrusters for attitude and orbit control. It is not specified whether the given engine is the sole means of propulsion or whether other types of engine are also used on a spacecraft.
To date, it is the only operational MPD thruster to have flown in space as a propulsion system. Experimental prototypes were first flown on Soviet spacecraft. The applied-field MPD thruster in development at the Institute of Space Systems of the University of Stuttgart reached a thruster efficiency of 61.99% in 2019, corresponding to a specific ...
With private firms entering the space domain, Bellatrix Aerospace became the first commercial firm to bring out commercial Hall-effect thrusters. The current [when?] model of the thruster uses xenon as fuel. Tests were carried out at the spacecraft propulsion research laboratory in the Indian Institute of Science, Bengaluru. Heaterless cathode ...
