New type of propller that is 20 percent more thrust

Do you have the insurance or the wherewithal to protect the patent in court. Without one or the other the patent is worthless - I know from bitter experience!

If you don't have some form of registration, there is nothing to stop someone copying your design, patenting it themselves and then suing you and preventing you from exploiting your idea.
 
The propellor on boats is not that old. IIRC Brunel was the first to use it and the early ones were crude affairs.
It is a big step though.

Crude in execution, but surprisingly efficient. Great Britain's first propellor was actually pretty much as efficient as a modern design; it failed because 19th century fabrication techniques couldn't produce strong enough welded joints. Very interesting book on my shelf all about the design and history of Great Britain,which was an amazingly well-engineered vessel for such a pioneering type.
 
....... the engine is ...... well over 25 years old now ...........

There have been significant advances in propellor design in the intervening period.
I have become used to a Brunton Autoprop which self-pitches to match the load and the revs. It seems very good but there are several other propellors on the market which make the same claims. All have their merits and de-merits.
It begs the question "what is a better propellor?" . Is it for a yacht, a speedboat, a tug , a tanker and so on?.

Similarly with HMS Warrior. Unbelievably, they could haul the prop out of the water at sea to reduce the drag while under sail. They could even raise it to deck level and replace a blade as they carried a spare!
 
Have you contacted the major universities who do marine stuff, Southampton and Plymouth come to mind and do a joint venture with them?

Odd how people only look to unis in the south. I'm from the Isle of Wight but now live in Newcastle. I've been shown around the cavitation tunnel, wind/wave/current tank and main test tank at Newcastle Uni, and the facilities are something to behold. A reminder of how many ships were built on the Tyne, and how we completely missed the superyacht boat, while due east in Rendsburg, Lürssen have production line of GBP 50-100m boats on the go. Such a shame.

There's a wall of polished bronze props at Newcastle Uni which form the basis of international standards.

The academics aren't easy to cooperate with unless what you want help with happens to be exactly what they feel like researching.

It's more a case of having to fit in with the work that they have been able to get grant support for, which is decided by national or international committees. They will have more than enough to do working on the projects arising from these grant applications, and work that doesn't fit in with those activities simply can't be done, no matter how engaging it would be. Any "spare" time will be spent in working on the next round of grant applications! Universities I know also have strict finance rules that mean that lab time has to be paid for at an FEC valuation; that jacks the cost up.

I'm afraid there is very little space for "blue-sky" research these days - which I think is a shame, but that's life!
 
Sad to say that this YBW would appear to have been the target of a Nigerian Scammer


He/she has gone quiet all of a sudden.


Thank you but i have registered this design with the patent office in cardiff...


Link to your design? If it’s registered, it’ll be online and available for all to see.


Amazing things pop on boat-related design searches, BTW.

Someone clever enough to invent a more efficient prop would be expected to have better keyboard skills, spelling and grammar.
What would the academics at any uni think if they read his posts on this thread? A leg pull or scam?

On the other hand many of our great inventors, composers, scientists and mathematicians etc suffered from one of the many flavours of autism (Aspbergers)

Don't think it is a scam. He has posted the same thing before on the MOBO forum, but no takers.

Right, but how about someone who merely thinks he's invented a more efficient prop?

I can't see how it's a scam, and if it's a troll then it's a pretty feeble one.

He'd be OK even without registration if he could show prior art, but that would only overturn the other guy's patent, nor get the OP his own.

Absolutely. Another issue with these early propellers was that nobody knew about cavitation then, which didn't only cause material damage but also vibration and fatigue. As you say, the Great Britain's propeller was a remarkably good design, but waaaaay ahead of the materials and fabrication methods available.
