POE Hydrogen Fuel Cell
Airboats were originally designed to navigate the swamps in Florida and Louisiana. They are still in use today; in fact, the airboat rides in the Florida Everglades attract many tourists every year. Airboats are increasing in popularity, especially among rescue personnel. During hurricane Katrina thousands of flood victims and pets were rescued by airboats. Airboats also played an important role in the Minneapolis bridge collapse rescue efforts.
A company that gives swamp tours has decided that exhaust and loud engine noise in their current airboats is less than appealing to tourists. More importantly, the boats are affecting the proximity of wildlife to the boat. They believe that if their engines did not emit fumes and were less noisy, their swamp tour would easily beat the competition.
To meet the requirements of this challenge you must design, construct, and test a prototype airboat that uses fuel cells as the power source. The prototye will have high speed capabilities. Other teams also hope to design the boat that the company will ultimately decide to purchase. They will choose the boat that provides a combination of high quality and speed.
- Define the Problem—review these rules and write a synopsis in your engineer's notebook.
- Generate Concepts—brainstorm ideas. Research the topic using available resources. Document your research. Perform tests on various motors and propellers using the hydrogen fuel cell. Sketch possible solutions. Decide on a solution to develop further using some logical method.
- Develop a Solution—sketch the final design in your engineer's notebook. Annotate the sketch. Show it to the teacher for approval. Could someone else build your design just by looking at your notebook?
- Construct and Test a Prototype
Evaluate the Solution—compare your performance to other teams in the class. Decide on ways to improve your device for the next design itteration.
Present the Solution—provide a written report in the informational report format or an oral
- Construct the device out of approved materials.
- Test the device by participating in a double elimination tournament.
- Race your boat in a double elimination tournament. Each heat of the race will be against one other boat.The race course is a 12 foot long water tank that is 24 inches wide and will be filled with at least 3 inches of water.
- Your score will be 21 minus your best standing in either side of the brackets.
- This is an activity for teams of 1 or 2 students.
- The maximum allowed length is 12 inches and the maximum allowed beam is 10 inches.
- For safety reasons, propellers may not extend beyond the sides of the boat.
- The boat must be propelled by an air propeller powered by one or two hydrogen fuel cells.
- The boats must have sufficient stability to not capsize from the addition of the fuel cell(s). The purpose of this rule is to avoid fuel cells being ruined by being dumped into the tank.
- The boat must be able to support fuel cells in a way that lets them be readily removed and replaced for charging or to be used by another team.
- The fuel cell may be charged between rounds using the solar panel provided by the teacher.
- The boat may use any combination of motors and propellers, but the power can only be provided by no more than two hydrogen fuel cells provided by the teacher.
- Teams that cannot make the starting line within three minutes of being called will be eliminated from that race.
