MHD Generator Test

A small scale test of a magnetohydrodynamic (MHD) generator. The generator pulls electrical power out of a rocket engine. This goes on the end our quad rocket engine. It allows us to run the engine in two modes. One for thrust and the other for power generation.

There is a datalogger that is taking five samples per second of voltage and current across the electrodes.

What's to indicate that any electrical power is being generated? A voltmeter across the electrodes would have been helpful.

How much power did your test produce?

I'm confused as to how this (MHD) relates to JP-Aerospace's goals.

Arn't all of your planned engines POWERED by electricity? I thought your plan was to use electric propellers, and electric ion thrusters - both powered by solar power.

Using a chemical rocket (as in this video) to create electricity to in-turn power an electric rocket - it's needlessly inefficient.

OK very good ! but Voltage and intensity ? P=u*I

Very good thinking! Two modes and no moving parts.
