An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms. The ions are then accelerated using electricity to create thrust.
This type of thruster can accelerate a large number of different liquid metals or alloys. The best performance (in terms of thrust efficiency and power-to-thrust ratio) can be obtained using high atomic weight alkali metals, such as cesium ( Cs , 133 amu) and rubidium ( Rb , 85.5 amu).
Current EHD thrusters are far less efficient than conventional engines. [15] An MIT researcher noted that ion thrusters have the potential to be far more efficient than conventional jet engines. [16] Unlike pure ion thruster rockets, the electrohydrodynamic principle does not apply in the vacuum of space. [17]
Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
The aircraft is an example of an ionocraft, which is powered by an ionic wind generated through controlled electrical discharge. The fuselage contains a stack of 54 lithium-polymer batteries. [ 2 ] [ 8 ] With the aid of a power supply unit these deliver a minimum of 20,000 volts of electrical potential, producing enough corona discharge (EMF ...

The dumbbell thruster exercise is a popular full-body movement trainers use to build strength, muscle, and power. Here's how to do it.
Such a thruster often generates the source plasma using radio frequency or microwave energy, using an external antenna. This fact, combined with the absence of hollow cathodes (which are sensitive to all but noble gases ), allows the possibility of using this thruster on a variety of propellants, from argon to carbon dioxide air mixtures to ...
