System Installs for the Next Run

July 5th, 2010

Away 47 is our next vehicle to head to the black.  Away 47 is another problem solving mission, a flight dedicated to troublingshooting a whole series of odds and ends. Saturday it got the position telemetry system installed along with the GPS antenna deck. The team also continued to put a lot of work into the new balloon release circuit and the trailer.

It looks like a big wooden fender, but it’s really a wing mounting deck.

Saturdays Work Session

June 28th, 2010

Saturday the team braved the baking parking lot to test fit the plane on the trailer. We had built ramps, wing stands, wing dollies, tail dollies and brackets. It all came together and the Sky Pup rolled up on the trailer. We took measurement for the next round, wing mounts and tie down brackets.

There was inside work as well. We’re still data crunching from the last mission set.  With four flights I  expect this set should be complete just before the lift off of the next one.

The data logger on the quad engine test stand is now talking to math cad.  That puts us one step closed to the first firing. Also for the quad we ran several more experiment with the MHD generator.

Everything I needed to know I learned from Science Fiction

Chief Engineers always exaggerate.

Never cross the streams.

Where every you go, there you are.

The Force is with you.

The enemy’s gate is down.

Always embed your website in top ten lists: www.jpaerospace.com

Never wear a red shirt.

Soon I will be invincible.

Take the BLUE pill.

Always know where your towel is at.

Can you identify where these came from?

MHD Generator for the Quad

June 24th, 2010

We spent a week trying to get the MHD generator for the Quad engine to produce power. The idea is that the magnetic system at the end of the engine is used in two modes. The first  mode is that of a magnetic nozzle increasing the thrust. The second mode is that of a Magnetohydrodynamic generator convert the chemical energy of the engine into electrical power.  Some parts of it’s climb to orbit the airship needs more thrust and sometimes it needs more electrical power. The tests with the first unit were a complete bust.  Taking Mike’s suggestion we made changes to the magnets and Paul’s suggestion we build a mini version just three inches long and a half inch in diameter.

We finally got the mini putting out power: 63 uA at 50mV.  A very humble beginning but at least it’s working.
