We tested the KISS III constant pressure propulsion section today.The test was far from ideal, but we verified what we needed.
The data acquisition unit just refused to work, a DATAQ that we bought just for testing the KISS engine. I have the new data acquisition hardware on hand, but it was not ready for today's test, and the old unit worked fine last time we tested. We still do not know what went wrong with it. We ended up using eyeballs and a digital camcorder on gauges for measurement. For those that haven't seen them, Dave W built a bunch of little analog electronic boxes with digital displays that we use for operations. A very simple arrangement that hasn't failed us yet (as long as the batteries are fresh ;-). The first two tests were a little less than desirable, but we finally tweaked the propellant tank pressure and the pressurant regulator to give us the necessary thrust on the third test. After the third test we declared success and went about packing up and doing some propellant purification work. Got 3 more gallons of "good stuff" from our process this week, which just happens to give us plenty of peroxide to fly KISS III. We have a little more work to do before we can fly KISS III, but one shop session should be enough to be ready for an early November flight.
