Static Draw Bar Pull of an Airboat

Hi y'all!
I am not into airboats or boating for that matter but am working on a machine design which may utilize an airboat propulsion system.
My very generic question: Is there data out there which shows the 'draw bar pull' of airboats with various engines and propellers? I am interested in the static pull force, i.e. if the airboat was tied up to the dock with a rope and a dynamometer.
Any info is greatly appreciated.
 
ok ill bite

ummm search the forum here and you will find some guys posting numbers.

you would not measure it with a dyno, its just a scale in LBs eg. the boat can pull 1500lbs of weight.

Big motor and big prop can make 2000lbs of force or so some guys on here have said :) @Waterthunder

what are you building
 
Call GTO Airboats in Ocala. They actually build wind machines using airboat setups and sell them to movie and TV production outfits form what I understand. They can probably answer your questions with regard to static pull force.
 
Thanks for the replies and pointing me towards GTO Airboats. I will contact them, for sure.

Can't disclose details here but it involves moving a large and heavy suspended object with a certain degree of accuracy using some sort of thruster or thrust generating device, like an airboat drive. It's still in the early conceptual stage. ;-)
 
We get a super top secret never been done before type inquiry probably every third or fourth year or so.
You should be aware that you may need a super top secret never been done before type of budget to implement your plan.
Sadly, this is not one of the more cost effective means of entertaining one's self.

In fact, I don't recall any of those in the past showing back up later to share their intent or the success they had with it.
Wishing you all the luck in the world, but don't be offended if we don't hold our breath. 🤷‍♂️

Wouldn't you be better off pushing it instead of pulling it so you don't have your prop blast fighting you? Or is this getting too close to the secret.

It will have to go both ways - push and pull, so the propeller does have a symmetric airfoil so it can be pitched in both directions.
 
Always good to see your posts! Slidin Gator. Thanks for your help in past. If you have any questions about LSA, let me know. Been trouble shooting and solving problems, I have found since buying this airboat.
Be on the Water!

Kinda gave up a bit of the top secret here, prop R&D, symmetrical airfoil, steering air vs creating "lift" with the dihedral at the root of said prop, I hope you share the outcome with us, seems like reinventing the wheel or airscrew for that matter, lol

Don't look like you'll be the first one to return later with your story of success. 😞


Maybe if you could teach a prop to drink Bud Light, you could also re-write the Laws of Physics.

That is funny right there!!!
To be honest, since I switched to Miller Lite or Yeungling my digestive system has been much better.
 
Reach out to Dave, (Waterthunder) he might just be able to point you in the right direction.
