Plasma Propulsion Engine
Transcript of Plasma Propulsion Engine
How does it work?
What is it?
Can be used for space travel.
Seems sci-fiction, but has been worked on since 1961.
It is a type of electric propulsion that generates thrust from superheated plasma.
What is Plasma?
One of the four fundamental states of matter. Neither being solid, liquid, or gas.
Comprises the major component of the Sun.
In the Beginning
Different kinds of the Plasma Propulsion Engine
The Present and Future.
VASIMR: Variable Specific Impulse Magnetoplasma Rocket.
Electro-magnetic thruster for spacecraft propulsion. Test phase will occur in 2014.
Predicted to shorten interplanetary travel substantially. Example: From Earth to Jupiter, originally 6 years, reduced to 14 months. Earth to Mars, originally 4 months, to 39 days.
Plasma Engine Propulsion
By: Simon Buser and Ian Callaway
An early plasma propulsion engine was created at a research center in Cleveland Ohio in 1961.
Helicon Double Layer Thruster: Uses radio waves to create plasma and accelerate the plasma away from the engine. Creates a velocity 10 times more powerful than that of chemical rockets.
SPT series: Started in the Soviet Union in the 1970's and has a thrust of 1.5N, 65% efficiency, and weighs only 23kg.
What this can do for NASA:
Conventional thrusters consume 7.5 tons of propellent a year, while the plasma rockets will consume 0.3 tons a year.
The plasma rocket has prolonged life time and higher power density than conventional rockets.
