UPM 2011 International Academic Competition on Underwater Glider – Ocean Glider - design (Competition Over)

Ocean gliders are small, crewless, underwater vessels with a low-consumption propulsion system.  They have a great deal of autonomy as they use light electrical batteries.
The majority of underwater vessels use propellers to move through the water.  Vessels that use propellers are faster but they need a lot of energy to maintain their speed.  Ocean gliders move by changing their floatability, giving rise to such a change in their density that it makes them more or less denser that the water through surrounding them.   This change in floatability causes the ocean glider to sink or float in the ocean.   When the ocean gliders dive or surface their flaps generate and forward motion.   Ocean gliders are capable of gliding both when they surface and when they dive.
In a typical configuration, an ocean glider changes it density by moving a small piston.  As the density is the quotient between the mass and the volume, and the mass of the ocean glider is constant, it is enough to modify the volume by moving the piston.  A small variation in the volume (like half a cup) is enough to make the glider surface and dive through the water.  Other types of configuration are welcome in this competition for the ocean gliders.
The objectives of this international academic competition are:
• Promote and develop ocean gliders.
• Involve university students in the design of ocean gliders.
• Optimize the design of ocean gliders.
• Obtain new ideas for the scientific or business application of ocean gliders in the future.
This is an international competition for the design of conceptual models of radio controlled ocean gliders in accordance with the requirements of the basis of the competition.  There has to be the future applications for the ocean gliders.
The competition is made up of 8 phases, with the following timetable:
Phase 1. Enrolment
Until the 15th of June 2011
Phase 2. Presentation of the project
Until the 2nd of September 2011
Phase 3. Announcement of the finalists
23rd of September 2011
Phase 4. Manufacture
Until the 14th of December 2011
Phase 5. Delivery of the ocean gliders
14th of December 2011
Phase 6. Preliminary trials
14th of December 2011
Phase 7. Competition
15th of December 2011
Phase 8. Announcement of the winners and prize giving
16th of December 2011
There are 4 prize categories:
1. The UPM prizes for the optimization of the design.
First prize: 1,200 Euros
Second prize: 900 Euros
2. Dassault Systèmes prizes.
All of the prizewinning teams will also be awarded educational qualifications together with online courses in the Dassault Systèmes design tools.
Dassault Systémes will award a prize to the Spanish team that best applies PLM solutions with a view to installing them in their facilities in France.
3. The UPM prize for the best idea for the scientific or business application for ocean gliders.
Prize: 1,000 Euros
4. The SOCIB prize for the best technological innovation.
It consists of a trip to Mallorca to participate in an ICTS SOCIB ocean gliders mission, together with SOCIB and IMEDEA researchers.
