Progress

Currently-configured suit with Mark II home-built convolute elbow section on the left, and on the right (in black/yellow) the off-the-rack, industrial hosing convolute elbow section (already tested on the sleeve testbed, but not yet on the suit under pressure) that is lighter, cheaper and simpler. SO suit Mark I was the essential suit without convolute elbows that gave essential function but limited mobility at operational pressures of up to 3.5psi: Mark II was same suit but with the home-constructed (on left) heavy convolutes that gave significantly better mobility at operating pressures; Mark III will be same suit with both lighter, cheaper and simpler convolutes (black/yellow) to give even better mobility at high suit pressures. Mark IV will be an entirely new suit with either these new elbow sections, or a different variety under construction & testing at present. We'll only give that new approach another month or so, then make the decision and build Mark IV; to make a flight at the end of the year, we have always to move ahead, even if only a little, every day.

Open House!

Our first Open House of 2015 was a lot of fun, with lots of visitors -- just a few shown in the photo above (click to enlarge) -- from Portland State University's Aerospace Society and Portland State University Rapid Prototyping Group. We also had a visiting marine historian from the Explorers Club (he's dived to over 13,000 feet in Russian submersibles) and a couple of people simply walking by the porch saw the interesting devices inside, and came in to see what was up. Great fun!

Cold Chamber!

Last summer we had some good test experiences in a cold chamber, testing the suit and its Life Support System at -20F. We'll be back in there this coming year for a more controlled test, which will be written up as a technical brief. The three technical briefs so far written can be found here. Photo by A. Magruder.

New Research Brief Online

Between the thrilling and dramatic tests, there are hundreds of hours of building and planning the pressure suit project. I am organizing the precipitates of this work into research briefs that I archive online in PDF format; you can find the latest by clicking here.

At TEDx Brussels

My buddy Louis-Philippe Loncke is wearing the suit on stage as I describe its function and construction. A good week in Brussels and Toronto/Waterloo!

Video Archive of My Talk at the Perimeter Institute for Theoretical Physics

What a week, first at TEDx Brussels (link later), then the Perimeter Institute for Theoretical Physics, where I was thrilled to be given an office for the day in the Hawking Wing.
