Alpine Downhill and Speed-Skiing,ft on the body will be important. Since the lift will indirectly reduce the ski friction, a reduction of the friction coefficient μ could be applied. For the speed-skier at velocities around 250 km/h, the lift force will seriously influence the stability of the athlete.

Computer simulation of ski jumping based on wind tunnel data,enables the calculation of the flight path; the inverse approach starts out from flight path data and results in the time-funtions of the lift of drag forces and areas which can be used for a quantitative flight analysis.

Skin Suit Aerodynamics in Speed Skating,ifferent suits on speed skating performances just with field measurements is a difficult task. In fact, field measurements and competition results do not clearly show the effect of using different suits. Industries and Olympic committees have then been pushed to increase the number of laboratory tes

Alpine Downhill and Speed-Skiing,ed the lift force on the cross-country skier since the velocity is relatively low. For an alpine skier and especially a speed-skier the aerodynamic lift on the body will be important. Since the lift will indirectly reduce the ski friction, a reduction of the friction coefficient μ could be applied.

Performance factors in ski jumping,g movement and the utilisation of aerodynamic lift, accurate timing of the take-off jump with respect to the edge of the ramp, appropriate angular momentum at take-off in order to obtain an aerodynamically advantageous and stable flight position as soon as possible, choice of advantageous body and e
