Magnetoplasma Dynamic Thruster Quiz

What is the primary advantage of using plasma in MPD thrusters compared to traditional chemical rockets?

• Plasma is more environmentally friendly.

• Plasma is cheaper to produce.

• Plasma can be fired at much higher speeds.

• Plasma requires less maintenance.

In the self-field MPD Thruster, what is the role of the electron stream?

• To generate plasma by knocking electrons away from gas atoms.

• To create a magnetic field.

• To provide structural support.

• To cool down the thruster.

What is the Lorent force responsible for in the self-field MPD Thruster?

• Creating a circular magnetic field.

• Pushing charged particles away.

• Heating the plasma.

• Stabilizing the thruster.

How does the applied field MPD Thruster differ from the self-field version?

• It uses less power.

• It relies on an external magnetic field for higher thrust.

• It is smaller in size.

• It does not require a power source.

What is a major drawback of the applied field MPD Thruster?

• It is too heavy for space travel.

• It produces too much noise.

• It requires nuclear reactors for power, which are currently illegal.

• It cannot operate in a vacuum.
