This video from Greg at Omen foils has the best explanation of our foil geometry and the forces involved that I have found, well worth a watch.....It shows the difference between our geometry and an airplanes , this is what I was poorly describing when talking about a lever.
Jaumet.......Could you comment on these 2 scenarios....
Firstly as you can see in Gregs video it is both drag and front wing -Cm that contribute to downward pitching in our foil systems.
Scenario 1...........High camber ( moderate rear camber) front foil.......High lift profile .....lets say a Cm of -.1 at 1 degree AOA
Scenario 2....... Moderate camber reflexed profile......Low/ Medium lift profile.......Cm -.05 at 1 degree AOA
Due to the lower lift of the reflexed foil we assume we need to increase the foil area to match higher cambered foils lift for the same rider, same conditions etc...lets assume 12% larger.... The larger front wing has a lower -Cm but due to being larger more parasitic drag from the increased surface area.
With both drag and negative Cm causing our board to pitch down which scenorio will pitch down worse at high speed?
And sorry in advance as I know there is so much math involved you won't want to answer this and I don't expect you to. I am just interested in your thoughts.... 😎 And no I have not done the math.
Thanks
