Mini MHD

Sunday, October 31st, 2010

We did the first two firings of the mini MHD generator today.

This unit can be unclamped and easily disassembled. This gives up a rapid turn around for a lot more testing.

Here’s a pics from our Away 25 mission at 100,000 feet.

ToDo’s for Today

Saturday, October 30th, 2010

Today we’re going to be working on the crew module mockup and the MHD generators. We’re experimenting with a stand up configuration for the crew for the module. The nice thing about a full size mockup is that you get to experiment and find out quickly what works and what ideas to later pretend you never had.

We’re finishing up a mini-MHD generator. This one will use even smaller rocket motors. The mini will be used as a base for testing the sensors. With the smaller engines we can fired several times a day pretty cheaply.  If all goes well with the sensor we’re going to try and get a firing in on the quads MHD generator.

We still have the 50 foot airbeam we want to test at 4 psi. However that’s best done outside and it looks like rain tomorrow, (we fire the rockets under an awning).

10MW MHD Space Power System

We’re been studying other people’s magnetohydrodynamic generators. This one is pretty interesting. It’s a Russian space based MHD generator that uses a liquid rocket engine at it’s core.

JPA in SuperFreakonomics

At least the Ascender is. Check out page 210 of the new illustrated edition of SuperFreakonomics. There is an illustration of two Ascenders carrying a hose up into the stratosphere. We consulted on that project and they went with Ascenders in their planning. However we were not credited in the SuperFreakonomics book. Oh well, you can’t win them all.  There are so many folks involved it would take an entire book just to credit everybody.

The Ascenders do look cool though holding up the hose to the sky.

MHD Generator Test Firing

Today we did the third test of our MagnetoHydroDynamic generator.
