Hi I'm a university student, Im in my 3rd year and im doing a project on designing a landyacht.

I need some help with the sails part
However I'm very new to how sails work and only know the simple fundementals of sails.
I have to do some calculations on the velocity of a land yacht, just some rough ones to start with what I don't know is how I can calculate how much force the sail generates from a given wind speed, and once I calculate this forward force, how do I calculate the velocity of the land yacht, given the land yacht drag and wheel drag

I would really appriciate it, if someone could shed some light on the subject so my question is how do I calculate the speed of the land yacht?

Thank you in advance!

Hi RED01,
Good on yer! You come all this way just to find out that you have a perfectly good Sail Maker in your own country[}:)]
I have just been in contact with John of http://www.sailrepair.co.uk/shopoffers.htm
info@sailrepair.co.uk
He has given me some really good advice.
I do not know where he is nor yourself, regarding County location but contact him and mention Ron Williams .Tassie

Go research your project.

Go here to see a Land Yacht video etc.

Who was that Dublahumpty Wheel barra fella that you guys were talking about a month back. You know the one that tested Sails in a Wind Tunnel affair and wrote a book. That may be of some use RED 01.

Ron do yourself a favor get hold of a copy of ...
"C.A. Marchaj Aero-Hydrodynamics of sailing" ISBN 0-396-07739-0 most public libraries can get a copy.
Almost ALL of the questions that are going through your mind have tried and tested.
Also several chapters on high speed and land / ice sailing.
