The quad engine is getting closer and closer to firing. The oxidizer plumbing is done. We did a cold flow test at 100 psi. It turns on and off just like it should from the remote control box. We also modified our Hypertech ignition system for the quad. Lastly we’ve mounted the whole thing on tracks.
Next the instrumentation needs to be added so we’ll know what’s going on. Then the entire system will get mounted on a cart to make setup in the desert easier.
Saturday was a day of sewing, circuits and foam cutting. We need a little more power output from the new propeller driven balloon release (propeller as in the chip). Mike spent the day bread boarding the modification circuit. Paul was busy at the sewing machine creating a wider tear panel for our small balloon bag. The balloon bag is just the right size for sea level launches but too small for launches the 4000 foot Black Rock lake bed. The wider tear panel will add just the right amount of room. Ethan our evil intern wrestled with triangles all day making antenna mounts for the next set of vehicles (the triangles almost had him, but he won out in the end).
Here’s the first video from the last mission set. It shows what it takes to get these things in the air. This is fill and launch one of four. This one is dedicated to the balloon fill team.
