by Kitesurfing is a wind-based sport where the kiter can travel on water or snow propelled by a large kite connected directly to the kiter.
The kite has an aerodynamic shape similar to the wing of an aircraft wing; the upward force of the wind into the kite – lift – counteracts the downward force of weight – drag of the kite – and is added to the thrust, i.e. the traction given by wind itself.
There are several parameters that affect the way a kite flies.
Riccardo Mereu, Professor of Innovative Technologies for Energy, explains them.
