DESIRABLE GLIDING STYLES AND TECHNIQUES IN SKI JUMPING

Desirable flight styles and techniques in ski jumping were calculated on the basis of the new aerodynamic force data for three styles: class ic style, V style, and flat V style. In the V style and flat V style t wo skis are in a herringbone position in the frontal plane, whereas in the classic style the skis are parallel. Flat V style is more flat in the sagittal plane than V Style. The most effective style was the fla t V style if a ski jumper model did not change style during the glidin g phase, which was the late part of flight phase (distance was 110 m). If the model changed flight style, the model that changed from classi c style to V style at 1.3 s after takeoff or from flat V style to V st yle at 1.6 s could achieve 112.5 m. In addition, forward initial angul ar velocity was a positive factor to increase distance; in particular, the distance for the V style was sensitive to initial angular velocit y.
