-Hey Everyone



I'm designing a hovercraft for military applications at university. After researching, I haven't been able to find any information on how the hovercraft skirts have coped with things such as small arms fire etc. and how it has affected the performance of the hovercraft. Does anyone have any information regarding this subject, if so I would be extremely grateful for your comments and opinions.



Many Thanks

Two things come immediately to mind:



1) Have a look at the research into "ordinary" material/fabric under ballistic conditions, especially puncture size. If the puncture is relatively small it probably won't noticably affect the performance of the skirt.



2) But, if the small arms fire penetrates the skirt (highly likely given that it will be made of rubber/fabric) then it will probably pass into the cockpit or engine area causing further and more serious problems. I would have thought that the chances of the round damaging just the skirt would be quite small...

Contact Griffon Hovercraft http://www.griffonhovercraft.com/ (www.griffonhovercraft.com/)

They may be able to share experience on craft used by British Army in Iraq.

Hovercraft Museum may also have reports on (unsuccesful) attempts to blow up an SRN3 by exploding a sea mine under it.

Thanks guys,



The hovercraft will be armoured so the rounds won't be affecting the vital systems.

I have emailed Griffon but have had no responses at all.

Also tried getting in touch with someone from the 539 sqn Royal Marines who operated hovercraft but again, no response.

What would the feasibility of adding chain mail/plated armour around the skirt be? I've also come up with ways of replacing the skirt while in use but it would add so much weight and increase the height between the ground and the bottom of the hull.



Many Thanks

News update, Air commander is out of business! Besides, it's my experience you'll have to be a money spending customer to get any help or bad advice from this place.

Gary has always been helpful to me, and he's been a friend for over 15 years. Also- when you're doing this as a business instead of a hobby, you learn to be quite selective on how you spend your time. (message boards are for free info; businesses are for making money)

See below for details on the business change:

From the HCA website:

January 4, 2006



Air Commander Hovercraft, Inc. has announced the formation of a new company; Hovercraft Depot, Inc. As a result, Air Commander Hovercraft, Inc. has been dissolved in favor of the new Hovercraft Depot, Inc.



Hovercraft Depot, Inc. will provide parts, service, and accessories for Scat, Aerocruiser, Hovercraft Concepts, Hovercraft America, Sky Rider, Sea Breeze, Starship 500, RX 2000, Hover Jet, and homebuilt hovercraft owners.



The Air Commander product has been sold to Air Cushion Technologies, Inc.; an existing company in Hobe Sound, FL. Air Cushion Technologies will continue production of the Air Commander, product line, and maintained the 800 number and the website listing. Hovercraft Depot looks forward to their success in higher quality and volume.

Looks like this place is where one of the old US-SRN5's ended up!
