Bigger Motor

Saturday night we fired MHD generator test number 27. This was the our first with a composite motor, an Econjet F-20.

We incorporated the structural lessons from test 26m segmented top plate and forward electrode plate retention wires. The motor was double of thrust from test 26. We were anxious to see if it would all hold together. We need it to be able to handle a “J” class motor to be used on the desktop quad engine.  The structure held find but the cathode was completely eaten through. The composite motor also left a hard non conducting coating on the electrodes.

    What sort of data loggers do you use to determine current/voltage generated by this beautiful apparatus?

    We’re using a custom built datalogger with the basic stamp II as the processor. It loads it all live to a comma delimited file on a memory stick.
