Re: rear wings on boats
Here's a couple of pics of a 38 Signature that Pepe and the boys at Pantera got to pilot in Florida. According to them the customer wanted to use the wing to help lift the stern out of the water. Good news/Bad News...
The good news is it worked! The bad news was that it worked so well that above 90mph the wing started to lift the transom out so far they had no steering or propulsion and the boat would start to bow steer. Another OSO member bought this boat and intended to take the wing off. |
Re: rear wings on boats
saw this too...

so your opinion is right and his is wrong? everybody has their own perspective on things... "performance" is respective to what your used to i guess, run 130+ MPH cats all the time and a 70 MPH ride doesn't seem that fast anymore... and i don't think anybody brought up steps? :confused: |

Re: rear wings on boats
And here I just thought you worked on boats and vettes. :p Those 2 alone will take up all your time.
Very cool stuff. I love following those technologies. Well... as best you can on Discovery or TLC. Gary

Gary, Here is a small blurb on some of our Mars work, part of my "paying" job to fund all the other toy projects. - Greg

Everyone else here was having an interesting and informative discussion on what Baja has been testing. I just didn't see why one person needs to ruin a good thread by attacking the manufacturer. |

Just point the force the direction that you want it.
Oh, and if you rotate it "just right" it produces thrust for a propeller or lift again for a helicopter rotor. "Streamlining" is the coloqial term for minimumizing drag or disturbance to the airflow. Now days it's just called drag reduction. I won't get into boundary layers and viscous -vs- induced drag as it's time for lunch. -Greg I was waiting for you to find this thread. When are you going to calculate the lift of the beak again :D |
