The paper discusses the results of wind tunnel tests for different angular configurations (φ1 and φ2) of a V-style (Graf-Boklev style) ski jumper model. The range of tested angles of attack was α = -10, 20, 30, 40 (deg), depending on a configuration. The configurations of the Graf-Boklev style ski jumper model were compared with the classic parallel style of ski jumping with the ski-opening angle λ = 0. Kl as a configuration for the parallel style of ski jumping was used as the reference configuration for other configurations with different ski-opening angles, i.e. λ = 0, 15, 25, 45 (deg). The results obtained have been presented graphically as aerodynamic parameters within a specific angle of attack.
A physical model of the human-javelin system has been developed together with a mathematical model of javelin flight including its transverse elastic vibrations. Three kinds of parametric identifications were distinguished: geometrical, mass and aerodynamic. Numerical calculations were made for different initial velocities and throwing angles. The results obtained have been presented graphically.
