AUVSI Competition Team |
 |
|
|
|
|
A new project that aims to create a sub capable of competing in the 2007(8) AUVSI competition is starting up. Additional team members will be added to this site so that they may use it for reference etc until we create an official site for this new group. |

A new year |
|
|
|
|
|
Soon the project will be one year old. Mike has done some additional vehicle testing over the summer (which can be found in the file archive). The sub's been such a success that it remains active as a test-bed for synthetic vortex generator propulsion for us. No specific plans exist right now for the future but there is sure to be some development once the school years begins. |

Final Presentation |
|
|
|
|
|
We've completed our final review. Here's us with Dr. Mohseni after making our final review presentation to the advisory board.
Here's some videos we have of our sub performing extremely well and exceeding our original specifications.
Actuator Thrust Test (61.3 MB)
Translation (16.7 MB)
Rotatation (30.1 MB)
Forward (11.2 MB) |

Success |
|
|
|
|
|
After performing three fully-integrated system tests in the pool, our submarine performed brilliantly. The specified yaw rate of 2 RPM was met and exceeded in some rotation tests. Lateral translation was also achieved and was faster than specification. We have quite a few still images and video that will be up soon that document this. The Calamar-E project is officially a success.

Test phase |
|
|
|
|
|
The first sealing test has been performed with the sub's core structure/hull/skeleton. The electronics module and actuator drives as well as the rear propulsion system were not installed for this test as they were not required and aren't done anyway. Here are some images of the test at the Claire Small pool on Friday, 3/31, 2006.
This is the sub on its stand with the majority of the structure assembled. Rear cavity cups have not been installed yet in this photo.
Here's the sub strapped to a floating medical/rescue gurney/backboard for transportation. We also performed the main leakage test with it mounted to this for stability and weighting purposes. The right rear cavity cup is not installed either. At this point we still need it to work on the actuators with so a hole-expander and silicone sealant was used to seal that hole for this test.
This is the sub just floating. As it is in this photo (without the components mentioned above), it is approximately 75 lbs underweight to achieve neutral buoyancy.
This is the inside of the sub after the 2nd sealing and submersion. The paper was placed over locations we expected to see leakage occur (if it was to occur) and where the water would gather (the bottom). The main O-Ring mount also had toilet paper on it earlier but we didn't have a camera present for that.
The result of this qualitative test was that the sub did not leak at all. The images above show the paper as 100% dry indicating no water entered the vehicle. We also observed, visually, as we submerged it to ensure no water was leaking in. Our main seal and actuator cavities sealed perfectly which is excellent news for us |

We're making a land submarine |

|
Although we're somewhat behind schedule and our first testing is approaching fast, there has been quite a bit of progress.
