Hi @PierreB, this is clearly my field of interest and you can be sure that we will provide continuous results on this topic. But simply speaking now, the higher the flight speed the higher the aerodynamic loading and thus also the deformation of the kite. How this increased deformation affects the resultant aerodynamic force depends on the design of the kite. It is difficult to make a generic statement because there are many superimposing deformation effects. E.g. spanwise bending (anhedral & sweep), billowing/ballooning of wing sections,… Following Paul Thedens there will be Mikko Folkersma defending his PhD towards the summer. And we start a new PhD project on the topic
