A Voith-schneider unit is a horizontal paddle wheel

PM?

Ashley has sent me a pm containing a design for a revolutionary horizontal paddle wheel jet drive, despite our often demeaning remarks about hardboard Ashleys jet drive has a lot of potential.

The Ashley Supersonic Horizontal drive or ASH drive could revolutionise model boating and possibly render brushless motors obsolete.

The science is fairly complicated but briefly the diametrically opposed paddles spin so fast that the tips of the blades actually move at 350m/s which is faster than sound and the opposition of the wheels create a negative inertia of mass that creates an anti electro-magnetic lift which in basic terms means as the drive spins faster the boat becomes lighter and theoretically, if spun fast enough, could lift the boat out of the water.

Well done Ash the inventor of the ASH drive.

Hi Ashley

The Free plans on the net for the Atlas Lines Hydro would be a good starting point .

These are available in 21 and 3/4, 24, 26 and 1/2 and 42 inch.

But if you take the PDF files to a printer, you can resize them to your requirements.

I resized the Sea Hornet 25% bigger to 31 and 3/4 inches and the Sea Rover 20% bigger to 35 and 1/2 inches.

I started on 26 and 1/2 one and found I had the reshape the central nose area to get a Lipo battery forward for the balance of the boat, also added lead into the outer hull sections.

No room in the slim hull for batteries, radio and servo, so the main fuselage area is the only area.

I like the boat to be nose heavy to start( I can move the battery back a bit).

I have a 4mm flex drive installed with a surface prop(adjustable).

The surface prop will shower all the boats and boys!!!!

Hi Ashley

This one would fit the bill!!!!

A POD RACER !!!!

[Paul TParticipant @pault84577]

Hello Harry

Oddly enough I have looked at the pod racers (they call them lobsters) and part of their overall design is being included within my project.

Thank you for looking at designs and contributing to the search.

Harry, whereas your very nice boat does look a bit futuristic with all that hardware hanging out the back (as compared to the normal sorts of rear ends), it is still nothing but a rudder and prop in clear view and not so futuristic for a futuristic craft. Don't get me wrong, I am not saying I dislike the flexidrive, but a futuristic craft needs something else…and this could simply be a normal prop but hidden from view if you see what I mean.

My large Ecranoplan could fall into the futuristic craft slot, as it has jet engines on display as the propulsion method, but of course it has (in this case) a flexidrive setup but out of sight​.

I believe Paul T has looked at pod racers, they do appear to fit the bill as far as futurism and three-point designs go.

Hi Paul

How about an x-wing from Starwars as in the ones flying across the water in the new film. Sorry but if this was a spoiler.

[Andy CParticipant @andyc56856]

Hydrofoils would be under the water keeping the ship up and looking like like it is skimming just above it.

[Paul TParticipant @pault84577]

Hi Andy

When I read your post last night I thought there's no chance that the X fighter would work as a boat as it would be top heavy but it kept on going round…….. and round………………and round in my head so this morning I had a look at the film scene (yes you did spoil it) and the props used during filming.

With the landing gear down it could be a very basic three point hydroplane and the tip of the lower set of wings could be modified into sponsons which could contain motors and props.

C of G is very far back so stability is an issue but I will play around with the idea.

Paul

[Andy CParticipant @andyc56856]

Sorry about the spoiler. Could the nose have some extra weight added up front to trim it out? How about some ducted fans instead of props? Could also look at some of the other more land based vehicle, say a snow speeder or something similar.

[Diede van AbsParticipant @diedevanabs87670]

Hi Andy,

You would need all the weight you add to be as far AFT as possible or the CG is too far forward. Apart from that, you want fast ships to be as light as possible, so if you can make do without adding weight… thats all the better.

Steering?

[Paul TParticipant @pault84577]

Andy

The C of G is roughly at the wing root so its high and would make the model very unstable, even with locating the motors and batteries in the sponsons the model would be very difficult to operate.

Hello Dave

Hello Dave

Oh dear did that one get away from you.

FYI I've just put a very nice LIDL 'Steak and Stout Pie' in at 200° and I'm about to go and peel some spuds and carrots. To those who sneer at LIDL and ALDI all I can say is that you don't know what you're missing. For those who think that Paul's 2-ton X-Wing budgie will ever fly then watch this space…….. It could go on longer than either Global Warming or Saving The Hobby.

…..and very nice it was, too!

[Colin BishopModerator @colinbishop34627]

You are suitably globally warmed then Dave?

Colin

[Dave MilbournParticipant @davemilbourn48782]

Yup! A thousand calories can't all be wrong!

Still not convinced by tank steering a water-born X-wing fighter, though. I remember an old schoolfriend* describing rolling his FIAT 500 (original type, circa 1968) – "It just tripped up and fell over".

[ashley needhamParticipant @ashleyneedham69188]

As per DM misgivings, tank steeing is no good for fast craft due to the sudden loss of power on one side when turning;

My Alvis has tank steering and this effect is vey noticeable; it is a sort of brick shape, on a boat travelling on foils….

Ashley. DM I`ll come round to your place for tea, sounds great !

[Paul TParticipant @pault84577]

Dave / Ashley

If this X craft ever became a live project then I would probably end up fitting some kind of rudder or nozzle system but at the moment this is just a top heavy hypothetical 2 ton budgie.
