This year the new students will be building a UH-14P. The craft is a little larger than last year's UH-13P. We will also be modifying the design to include a second engine for the lift system. This ... http://ahsist.edublogs.org/2007/08/18/new-hovercraft-project-on-the-way/ The craft has come back from United Auto Collision where they did great job as always. We decided on a blue craft with a spray-on bed liner material for the horizontal surfaces to prevent someone from slipping when boarding or disembarking. I'll publish pictures when the craft is fully ... http://ahsist.edublogs.org/2007/08/14/uh-13p-back-from-paint/ You can see we didn't keep up the site like we should have. Things got incredibly hectic near the end of the project and it fell between the cracks. We have learned a lot and are looking forward to documenting the build better the next time through. We had successful ... http://ahsist.edublogs.org/2007/06/18/uh-13p-update/ This week we came in to see the inside of the duct had expanded with the foam used to attatch it to the deck. We had to cut off a section of fiberglass and foam to fix the problem. We began the process of mounting the shaft for the fan ... http://ahsist.edublogs.org/2007/04/09/lift-duct-moves-forward/ With the help of some very dedicated students we made some progress this week.

It was great to see us have more than 1 hour at a time to give to the craft. ... http://ahsist.edublogs.org/2007/04/01/spring-break-progress/ This was a very good week for the deck team. Lots of hard and quick work helped us aproach finishing the deck. We fixed the plywood lamination and made sure there were no defects. Next, we ran a router around the edge of the deck to make the plywood flush ... http://ahsist.edublogs.org/2007/03/24/week-of-progress/ This week was a slow week because, for a few days, we did not have a full crew. There was some vary important things that did get done though. One was the removing of extra foam so that the duct could sit at 30o from the deck. The other was the installation of the 1x6's. This ... http://ahsist.edublogs.org/2007/03/23/first-look-at-lift-duct-on-hull/ This week, we made an effort to laminate the foam deck with 1/8" plywood. We placed epoxy in between the plywood and the foam and then layed the plywood on top of the foam. Then, we put the entire deck into a vacuum bag to ensure that the plywood had ... http://ahsist.edublogs.org/2007/03/18/laminating-problems/ We made alot of progress this week. The lift duct has been constructed using layers of fiberglass epoxied to take the shape of the duct. It is fairly rigid and we believe it is the best answer to our problems. On Thursday we wrapped the fiberglass duct in 2-inch foam ... http://ahsist.edublogs.org/2007/03/18/lift-duct-takes-shape/ The lift group might have finaly found a material that will work. After struggleing with the 1/8 in plywood for a month, we gave up on that and have moved on. Our solution was found using layers of fiberglass as the inner material to provide durability to the duct. We ... http://ahsist.edublogs.org/2007/03/10/lift-duct-may-eventualy-get-finished/
