Here are some pics of our hovercraft, while the official webpage is being created. The pics are pretty large, so you'll have to deal with that for now. Anyways, the participants were Allen Wu (Course 16), Jordan McRae (Course 16) and William Chen (Course 6). We were funded in part by the Course 16 David J. Shapiro Award.
Prototype #1, using aircraft propellers, worked well, but was way too loud and ate batteries.
Prototype #2, using a vacuum centrifugal fan was much quieter.
You can see the inside of Prototype #2.
Skip ahead some time and you'll see the design we finally went with, configured for lift testing. It's an acrylic body sandwiching a G.A.R.(tm) foam ring.
It works! Hover testing.
The electronics bench. The first version of the hovercraft is radio controlled, so we had to interface a 4 channel receiver to the 10 lift/thrust fans.
The completed assembled hovercraft, with 8 directional fans and 2 lift fans. We decided to hook up two 4000mah lithium polymer batteries to increase runtime.
You can see our flag in this picture - the basilisk really has four legs, they're just not visible from this angle.
Ready for some outdoors testing.
And then water testing - see the power emanating from the hovercraft.
That's all for now. Hopefully we can add gyros, gps, autonomous control and all sorts of other good stuff in the future.
Here's a video of spin testing: Click. More coming later.
