  • To study the design problem and evaluate the resisting wind ability for a double balloon system with tether and net, the mathematical model of the system was established consider of the effect of wind, it includes the balloon’s mathematical model in the body-coordinate system, tether’s mathematical model based on non-limit analyze theory and the net’s mathematical model according as some assumptions. The nonlinear equations was linearized based on small disturbance assumption in the state of equilibrium. The response and stability of the double balloon system was analyzed with step wind input. The simulative results show that the design of the double balloon system is reasonable and the system is considerable for resisting wind.
