Scoot is now fully functional and has been operating for several months. Its debugged and very reliable. Looking at its statistics it has cut over...
Hi Brian - Its not new its just become more accessible. The first aero-elastic job I contracted to Norths was over 15 years ago. It was a mission...
Hi Doug, I think you need to rethink your logic. The smaller the boat the more sail area you can put up, so the SA/weight ratios are huge on model...
Doug - When are you going to go METRIC? Peter
Hi Doug - There are many ways to solve this problem and Tom says this as well and yes the conventional way is for the board to control lift/height...
What Tom is saying is analogous to trail on a bicycle/motorbike or castor on a car wheel. The larger the trail/caster the less sensitive it is to...
Hi All - More can be learned about this sort of thing by looking at PID control systems which were originally developed for autohelms by the way....
The flap has two purposes a) to control twist and b) to control the flow of air onto the rear element. Flaps are not nozzles. The aim is to keep...
No the idea is not to fill the gap. The two elements have independent airflows. The idea is to bend the air more. A single element can only bend...
The "fellow" explains how the trim tab works on the first element of the wing. A trim tab is used to either control the downstream airflow onto...
There's a lot to learn about composites. Most fabric suppliers have lots of info about this area. http://www.gurit.com/product-brochures.aspx...
Plain weave glass is not stiff or strong vs a multiaxial cloth as ther PW fibres are crimped (bent). So if you used a 600gsm quadaxial (where the...
there are several plywood structural codes that specify its stiffness. AS1720 for instance specifies the short duration modulus for F17 plywood as...
What are the units of your modulus figures? plus can yopu also spec the glass in g/m2 for us metric people. Peter
The siurface pierching V foil is not really "new" its been in use for decades on ferries, naval ships and other boats . TNZ however did cantilever...
