Abstract
We have measured aerodynamic forces acting on a ski-jumping robot. The commercially available robot was applied for the wind tunnel test to measure aerodynamic forces in the transient phases just after the takeoff and before the landing. The robot moves in the direction of nose-down rotation in the take-off phase, while it does in the direction of nose-up rotation in the landing phase. It was found that the lift increased at the beginning of nose-up rotation in the landing phase, and then it decreased until the body coincided with the vertical direction.
