ジャンピングバルーンの動的特性

抄録

Dynamic response of a jumping balloon was focused in the present paper. Differential equations of motion for the balloon-pilot system were derived as for two degrees of freedom. Numerical simulation was performed to figure out the characteristics of vertical movement of the balloon-pilot system, and it was found that the system was stabilized and controlled by attaching an extending rope to the pilot as for balance. Effects of spring constants and balancing rope density upon the dynamic behavior of the system were identified. The jumping balloon is significantly improved by the present simple technique and is expected as one af new sky-sports.
