Today in the morning I took pictures of all our prototype torpedo's with their measurements . After school we had a conference call with ASU about the science festival sometime in February or March. As the conference call was in session I decided to take a couple of notes.

Today Kelly, Joach, Martin, Alexis, and myself worked on creating prototype torpedo's for the AUV. The first one we made was of a plastic material, it was about half a inch long. We tested in air and it worked awesome, in water not so well. On our second attempt we made a larger torpedo of the same material but double the length. That one also ended up in failure. Our third and final try of the day was made of aluminum. The aluminum torpedo worked okay but was not very hydrodynamic. Our next plan is to add some fins to make it more hydrodynamic. As a result I am reading up on the concept of hydrodynamics.

Today after school Timmy and I went to the library to print out some tax credit brochures and letters. We didn't get to print them today so we have to wait untill Monday morning. Also the team had a movie Friday where we watched "October Sky". Although the movie was playing I went in and out of the room to see how much progress David had made on fixing several small problems on the lathe. Finally we didn't get to start making our prototype projectile for the AUVSI, we'll have to start them Monday morning.
