It's been a while since I've been here, not much progress on my VTOL project. But figured I'd post my physics project in the mean time.
Well it was build in a bit of a hurry. I had all semester to do it but procrastination won out again and I was spending the last 3 days of in a mad rush to get it done. I started Saturday cut out the rough shape out of foam board and another that was about 2" smaller around the perimeter, added some supports, taped a some fabric around it added a IPS motor and presto hovercraft.
The fabric leaked air badly so I put a backing of silicone on it to seal it(that added about 7oz...), that took all day Sunday and Monday... Well lucky we ran out of time in class Tuesday for me to demonstrate the hovercraft because I blew the motor trying to get it lift. So I visited to local hobby shop and my $100 budget when out the window but it was worth it :cool:
I still had to use an IPS motor and prop for movement and had to have another heavy battery because the LiPo would have fried them. I didn't event have time to mount the servos I hot glued everything down at the last minute :D
Wish I would have looked here first tho, looking at the hovercrafts here mine's like a tank lol. I can't wait till I cut half the weight off and get another brushless motor.
The day of the demonstration it worked vary well on concrete but not grass and was a bit slow. was funny to see it struggle to fight the wind but it worked. I got a 99% for a grade the -1% was for spelling on my report -_-
With the success of that I have 2 friends that want to make one :D
Any suggestions are welcome, I do plan on adding a cowling around the lift fan and completely revamping the push motor and rudder. I'm wanting to use this as a test bed for my VTOL prop designs too.
Hope to get a video up tomorrow when it's light out.
