Abstract:

Mathematical tools were developed previously to analyze the dynamic behavior of tethered balloon systems. The model for the tethered balloon system consists of the streamlined balloon and a tether made up of three discrete links. The tools consist of the linearized characteristic equations which incorporate the physical, aerodynamic and mass characteristics of the system and the dynamic simulation computer program which determines the response of the tethered balloon system to wind disturbances. A tethered balloon system consisting of a 70,000 cubic foot aerodynamically shaped balloon and a 0.52 inch diameter Nolaro tether was flown at Fair Site on White Sands Missile Range to obtain experimental motion data.
