Away 28 Reimagined

The new frame for Away 28 is just about complete. The team assembled the new drum mount and installed it last night. The next step will be assembling the new drum.

Away 28 Reimagined

Busy

All kinds of work has been happening over quite a few vehicles.
Here’s what has been going on in the last week:

The Tuesday night crew has been knocking out carbon clamps for Away 28. They also replaced the carbon vertical poles.

Mark and Drew laying carbon
On Saturday we were cutting and sewing ten by twenty foot fabric panels. These will set inside the balloon bag under the balloon during launch. It allows us to adjust the position of the balloon. Both sewing machines were flying as the parts were hemmed, joined, (pulled apart again) and rejoined. After this post I’m going to sew handles on the corners and it will be done.

The sensor cables on the tandem were too long. Off they came. They got trimmed, new connectors put on and remounted on the airship.

A wire running near the parachute cannon on Tandem was giving us trouble. There is a eight watt transmitter nearby and the wire was picking up noise. We tried filtering it out, but it was still a problem. We replaced the wire with coax. It’s a bit heavy but, it should do the trick.

We continued testing on the airship’s main controller. One glitch found and fixed.

Heavy duty construction was happening on the crew module mock up. The aluminum bracing for the crew couches was completed.

We completed the frames for Away 35, 36 and 37. They just look like skeletons without there decks and gear. Like a Christmas tree before you decorate it.

And last we started pulling the parts together for the Light Nose Cone project.

The Silence of Space?

I read the comment recently about the silence of space.
I think this idea started with the line from the movie Aliens,
“In space, no one can hear you scream”.

This is an odd notion. Space is completely filled with pulses,
beats, tones across the entire spectrum. Even gravity has
waves to it. Jupiter acts like four million heavy metal bands
are trapped inside.

It’s as if we’re in a symphony hall and Beethoven is thunder
around us shaking the shingles off the roof and we think to
ourselves, “why is it so quite in here?”

Balloon Tests the Sequel

It was back out to the park to work on the balloon nozzle issue. This test was critical to the launch of the Tandem airship. It was a beautiful day. Even though the solution was not at all what we expected the solution was in hand by the end of the day.

Here’s the pics of the test.

For background here is the first round of tests.

Growing the Team

The team has grown by nine folks in the last month. That’s a lot considering we’re a pretty small team to start with. New people are thrown right into the mix building hardware. We’re constantly training and cross training with the old hands so new people don’t really change the pace. Tuesday we used the making of a mount for Away 28 as a lesson in molding carbon.

Serial Port

Finally! I’ve been debugging a serial port on a new controller for days. I’ve made dozens of these things and there’s not at lot to it. This was making me a bit bonkers. It ended up being a sharp point on a bottom on a chip socket that was poking through the insulation of a wire and intermittly applying 12 volts to the attention line. The wire was moved and sharp point clipped, and a few more gray hairs added. I guess that’s what testing is for.  This one will fly on Away 36 this summer.

Saturday at the Ship Factory

Every corner of the shop was in action on Saturday.

The Tandems main flight controller was brought back on line. It had undergone a major overhaul. Panels for two new parachute were cut out.

We’re ramping up for quite a few flight this year. Over the next month we’ll be replicating equipment for five vehicle. Three of the vehicles will be high racks. Foam was flying as eight decks were cut out.
The last six panels of the new balloon bag were sew together. At 28 feet a piece it was quite a job.

We moving from a wood and wire to a metal and wood version of the crew module. The frames for the couches were assembled. In a few months it will be ready for training and fit studies.

We also did some simulator work and in the middle of it all the Sacramento NSS had a meeting. Definitely a space day!

Don’t bother me I’m debugging.

New Parachutes!

Paul loves triangles…

Just what is he thinking about?

Away 28 Drum Assembly

The Tuesday night crew has been revamping the Away 28 vehicle. So far the focus has been on the drum assembly that holds the balloon. They’re making great progress.

Tuesday nights are also the time we work on the simulators. It’s moving forward bit by bit…. (sorry I couldn’t resist).
