Název v původním jazyce

Study of close ground proximity on a flexible wing

Popis výsledku v původním jazyce

The coupling of the aerodynamic forces and the elastic deformation of a generic wing approaching the ground and its consequences are studied. Static aero-elastic phenomena are modeled in a coupled manner. The aerodynamic characteristics of the wing respecting the deformation of the wing caused by the aerodynamic loads and the gravitational force with respect to the wing flexibility are computed using a relatively simple method suitable for the wings of the higher aspect ratios. The presented study is focused on the very close proximity of a wing to the ground as it is the case during a sailplane take-off run. The study was initiated by the problems encountered during sailplane take-off where the touch of the wingtip with the ground during the take-off run is not uncommon.
