July 29th, 2009 - Water valve and Nozzle mounted to the Cobra

Here are the results from yesterday's experiments. Our large-scale ice chip and snow delivery system was modified by adding a water valve on the nozzle to deliver a flat-spray of water on the deposited ice. We have also mounted it on the Cobra and programmed the valve to open from the point of origin to the finish along a straight path.

The rate of deposition was approximately 1/10" per iteration. Modifications to the nozzle and water-to-snow ratio are paramount in moving forward with this project.

July 16th, 2009 - Walk-in freezer experiement

Inside of a -20 °C freezer-room in the McGill University Engineering complex, Professor Sijpkes, Robert Pontarelli and I conducted an experiment to validate our ice-chip/snow delivery system.

Our system includes a Wye-channel, extended with rigid transport tubing, which is then attached to flexible tubing, so that we have the ability to manipulate the deposition path via the nozzle which is found at the base of the entire system.

Using a large air compressor, the lab-made ice chips and snow are transported via the tubing and finally out of the deposition nozzle. Thus far, the results have been extremely positive and may open up several possibilities for the development of this system and future concepts for the project.
