you need the air to be forcing the canopy back due to the low pressure created behind the canopy
Yes and no grass popper I dont think low pressure behind the kite canopy is whats flipping it over? Its a bluff body type wind force.
The fatter the profile the Higher away the C.O.E will be from the leading edge so will the centre of force acting to tip the kite. So you are right about that.
More interested in the effects on kite preformance in the air and how luff curve will effect flight.
I will SEE you your wood models and Raise you a paper model (take a bit of paper and cut a luff curve in it and put it LE down and then roll it off the desk) Seee it flipped easier didnt it?
All my wood models float ok but i be buggered if i can get then to fly unless i tow them at 100 km/h behind the car.
Big airs soft landings
