Balloon Nozzle Height Tests 2
Problem: The balloon nozzle is too high.
Solution: The Origami balloon.
See Part One
On
Saturday we conducted the follow-on balloon nozzle lowering tests
Our earlier testing with small and medium balloons make it
appear that the solution was in hand. It's never as easy as it seems.
The large 4000g balloon behaved (or misbehaved), very different than
the smaller model. Our plan was to conduct one test with air in the
balloon than a second with helium. It took about a dozen air
inflations to find the techniques for keeping the balloon nozzle low.
Instead of a three hour test it took just over eight hours.
In the end we had success. We were able to repeatably put the balloon nozzle at 40 inches off the ground at peak balloon fill.
The day was also a good equipment shakedown. We discover that our
helium flowmeter is broke and the vans generator needs a tuneup.
We just need to sell eight space ads to cover it...
