hovercraft skirt

[HoverTim]

yse you are right designing a modle hovercraft skirt is a night mare so far i have used plans that come with skirts i cant stress this enough dont get some ply and a motor and try and make one as these will not work that well start off wih the Griffon 2000 TDX or the griffon 600 kit a bit off topic i wnt to the hovercraft museum last week to gete few mesurements for the well deck and i had the well deck in the van i alos has the SRN6 MK1 S so i took some pics of my modle in from of the real things

I suppose this was meant to be a reply to the other thread. Either way I agree with hovertim that you should build a griffon first to understand how these things work. I built one when I was 14 and it gave me a perfect basis for making hovercraft. I am 19 now and I can build them out of nothing.

well my first craft i designed myself it works with a few hicups but nothing to major i had only seen two hovercrafts when desinging it the rest was just based on how thay work which i did need a fair anount of recearch for it but it wasnt based on any craft

How do I keep my bag skirt from taking on water? The first craft I built had holes in the bag on the inside so air could be pushed under the craft for lift. This resulted in water (and rocks) getting into the skirt. How can I keep this from happening? Should I totally seal off the skirt and force air in the planum chamber a different way? If so how?

I have two ideas on how to fix this problem, but I don't know if either will work:

1. Put very small holes in the bottom of the bag somewhat toward the inside to force the water out and direct air into the plenum chamber.

2. Split the air from the lift motor and direct some directly into the plenum chanmer and the rest into the bag?

Any other ideas?

Thanks,

the second one is a good idea out of interest what material are you using for your skirt putting small hole may upset the airflow as the air will take the least path of reistance for reaserch see http://www.model-hovercraft.com/2000tdx/2000tdxhullplan1.html also http://www.rc-hovercraft.co.uk/infoframes.html
