Vasimr engine

The Variable Specific Impulse Magnetoplasma Rocket (VASIMR ®) engine is a new type of electric thruster with many unique advantages.In a VASIMR ® engine, gas such as argon, xenon, or hydrogen is injected into a tube surrounded by a magnet and a series of two radio wave (RF) couplers The couplers turn cold gas into superheated plasma and the rocket's magnetic nozzle converts the plasma. The VASIMR engine is able to vary its specific power and impulse. Like ion engines, it can operate for very long durations to provide slow but very economical propellant acceleration. It can also provide a very strong boost but less economical, provided you have a powerful source of electricity available The VASIMR engine, however, could change that, since it would use hydrogen, which is already generated as a waste product on the ISS. By using waste hydrogen and electricity from the solar panels of the ISS, VASIMR could maintain the ISS's orbit without requiring any additional fuel

The aim of this report is to survey the new ideas and technologies associated with electric propulsion.Specifically, the report covers the VASIMR engine by providing updates in this engine's. A VASIMR does not produce enough thrust to escape the Earth's gravity, but this is not a design flaw. Since ion engines work best in a vacuum, the VASIMR engine is suited for space travel only VASIMR, short for Variable Specific Impulse Magnetoplasma Rocket, uses radio waves to ionize a propellant into a plasma. Then, a magnetic field accelerates the plasma from the rocket engine, generating thrust. The VASIMR is being developed by Ad Astra Rocket Company, headquartered in Houston, TX The VASIMR engine, shown schematically in fig. 1., is. a high power, electrothermal plasma rocket, capable of. exhaust modulation at constant power.

The VASIMR engine was born from the imagination of the NASA astronaut, who flew on the space shuttle seven times during his NASA days and holds a Ph.D. in plasma physics from MIT. The plasma rocket technology will be the key to a Mars vehicle that will be faster and more efficient than any old-style chemical rocket The VASIMR engine is already at level 6, according to Chang-Diaz, who has worked on plasma rocket technology since the 1970s. I always felt there was a way to use that high-temperature plasma to. The VASIMR system would cut the trip to Mars by months according to Franklin Chang Diaz, a former MIT student, NASA astronaut, and now CEO of Ad Astra. Ad Astra Rocket was established in 2005 by former NASA astronaut Franklin Chang-Diaz. Ad Astra Rocket is working on one project in particular: the VASIMR plasma engine However, the VASIMR differs considerably from these other thrusters in that it lacks electrodes (a lack that enables the VASIMR to operate at much greater power densities) and has an inherent capability to achieve high and variable I sp. Both the ion engine and the SPT are electrostatic in nature and can only accelerate ions present in plasmas.

A VASIMR engine would consist of three electromagnets, powered by a small nuclear generator, linked together, that would provide the magnetic fields necessary to contain and control the plasma.
