Design and build of Hovercraft - any experts?

My son is considering the design/build of a hovercraft as an A level
project, has anyone had a go? Any suggestions? Is it feasible as a school
project?
I've found alt.rec.hovercraft but pointers to other sources of info would be
gratefully received.

I built one as a schoolboy - basically attached a small glow-plug
motor & propellor to a pice of plywood with a hole in it, attached a
skirt made from heavy gauge plastic sheet, & started it up. Crude, but
it hovered; it also spun on its own axis owing to there being nothing
to counteract the reaction from the propellor.

Tony

The idea is to build one large enough for him to blast around the fields on;
torque reaction is probably something he'll need to fix - although it would
be very entertaining if he didn't ;-)

We built one when I was at school in the late 70's (well we bult 2)

I clearly recall managing to hit the single oak tree in a 90 acre
field.

They have been built on "Scrapheap Challenge" (on Channel 4 TV there are
some websites about the programme and the various challenges) in two
days by four people only one of whom would know anything about
hovercraft.

IIRC the hardest parts were propellors/fans and skirts.

Dave, I bought some plans for a hovercraft from Universal Hovercraft in the
states. (Haven't built it, and doubt I will ever get the time!!!)

If you need plans, their website might be some help to you:

Have a look at http://www.hovercraft.org.uk/hcgb.htm

They publish a lot of useful handbooks on the subject and will advise on
suppliers for all the hard to make/ find parts.

My father in law tells me that he once witnessed some engineers who
worked at the docks he was employed at near Rainham, Essex, build a
hovercraft from scrap.

IIRC, they used two or three motorbike engines to provide lift and
thrust, and a body made of wood, with a skirt of some canvas or thick
plastic. One or two engines drove fans downward into the plenum, the
other one drove it forward with a fan behind the driver - a chair was
bolted onto it.

Apparently they took this thing out on the Thames to rescue stuff that
had dropped overboard and floated away, that sort of thing. So it is
practical!
