Power Check



Yes -- 12+ volts and things are really coming together with the suit coolant pump running smoothly and just the smallest adjustments to make to the suit itself. But not today--this weekend I read the space book manuscript for the first time in two weeks, my coauthor and I have completely left it aside for that time to come back to it for a final editing pass with fresh eyes. Could I be ready for the full test at the end of the month? I think so! I need to recruit some helpers, as I simply can't do it alone!

Suit Coolant Epoxy Seal






Tonight I took an hour to finalize the coolant hose through-port; in the first picture, I'm mixing epoxy, with the coolant in/out hoses through the PVC fitting that will screw into the port on the suit; in the second photo, starting to pack it into the fitting, around the hoses; in the third, the fitting rotated and its second opening being packed, and in the fourth, a closeup of the rather messy, but well-packed epoxy job that I'll sand down to smooth later. When this hardens in the next 24 hours, it will make an airtight plug around the coolant hoses, so that when this fitting is screwed into the suit port hardware, pressure will not escape the fitting, around the coolant hoses. One of a dozen little jobs that are quickly coming together to be ready for an end-of-the-month full test!

Suit Coolant Pump Installed



Finally -- a functional coolant pump, hoses and connections! The two quick connections in my hand are for coolant fluid in and out; they pass through a port to be installed in the suit after I epoxy the fitting to be sure it's airtight. The clear, thin hoses will circulate body-cooling fluid through a mesh vest I'll wear inside the suit, under my thin long-john union suit. On the left, the small black module is the new, more powerful 12vDC pump (driven by the motorcycle battery on the right, which will be replaced by a car battery that I purchased today, but had to leave at the shop because a bus driver said it could be used as a weapon! I'll pick it up on Thu with a taxi). A switch on the main control panel turns the pump on and off; it will not run continuously, only when I need it. The clear plastic cylinder in the background, with the orange bands, contains the coolant fluid; just water now, but later, basically, antifreeze. Hard to believe it was November 2009 when Angela and I did the first test of the pressure suit, it's two years later and I think by the end of this month my test will see the whole system ready for a full test!

Making Towards Life

This piece, by Luigi Boccherini, makes towards life, while so much of our culture seems to make towards destruction and death. By the time we are 10 years old, the sociologists tell us, we have witnessed over 2,000 murders on television.

Flight Simulator



When I was in Barrow, Alaska a few winters ago, I visited with the Search and Rescue pilots who would be alerted if I'd been in an emergency. Touring their office, I was surprised to see one pilot seated at a PC, flying a flight simulator, like you see above. These computer programs have come so far that they're useful for pilots to keep up basic hand-eye coordination, muscle memory, and, probably most importantly, checklist procedures memory when they're not actually flying. So, now, sometimes late at night, when I can't sleep or need some item to work on the balloon project, but don't have it, I fly a flight simulator to keep me conversant with things like glancing at the altimeter to know my altitude, understanding the effects of winds (I can set clouds and winds at whatever altitudes etc. I want), and checklists; for example, in the screen grab above, I'm making my 'base' leg of the approach (which I learned in paragliding flight training) and have to keep an eye on my altitude, speed (not too fast, not too slow!), using flaps to decelerate at a certain time, my vertical speed (and whether it's positive or negative), drop landing gear at the right time, and so on as I maneuver in for a landing at dusk at an airstrip near San Francisco.
For the balloon project, the main things of relevance here are becoming familiar with the altimeter and the vertical speed indicator, both instruments on my current flight panel. Otherwise, not much here is directly relevant to flying a balloon, but there are balloon simulators out there, and I mean to get one. I will then connect that to some actuators that will activate my flight panel instruments, so that as the program runs on the computer, sitting at the controls I will be able to simulate flights while completely suited up in the pressurized pressure suit. That will be invaluable experience, just as simulator time is a major component of any pilot's training and skills maintenance.
Flying the simulator is also, I have to say, a lot of fun. I am certain that some elements make it sometimes harder to fly than an actual airplane; for example, there is no physical sensation of movement, that pilots use to help gauge what the aircraft is doing, and as good as the graphics are, depth perception is still difficult to simulate.
In the image I'm setting up landing in a twin-prop Cessna. I like twin-prop aircraft of any kind, and don't like much single-engine craft of any kind! I have been in enough of them--over Canada, Kenya, and Alaska--to realize that I don't like staking so much on just one engine!

Quick Test


Unable to focus on a piece of writing this morning, a little while ago I put on the helmet and pressurized the system. Still little bugs to iron out -- though just about anything other than perfect isn't 'little' at all -- but good to see they system come right up to good pressure and voltage. I need to seal off all the wiring after making the final connections, get the tank refilled, and make one or two adjustments to the pressure suit itself. Then, I think I'm ready for the full test.
