Dynamic response to turbulence of tethered lighter than air platforms
Dynamic response to turbulence of tethered lighter than air platforms
The study presented in this paper concerns the development of an algorithm, based on finite element analysis, for
the dynamic simulation of a tethered lighter-than-air balloon when subjected to operational conditions. The main
features of the algorithm are described, highlighting the advantages of this approach when performing dynamic
analysis. The input parameters considered in the method are derived from experimental and simulated data, which
are elaborated to obtain the static and dynamic atmospheric properties in terms of mean windspeed profile, discrete
gusts, and continuous turbulence. In particular, the algorithm is employed to perform a thorough analysis of a specific high-altitude tethered platform operating in a realistic design scenario. The dynamic behavior of the system is evaluated in terms of displacements and tether forces. The results, even though they are obtained for a specific example application, demonstrate the general viability of the algorithm proposed for the evaluation of the dynamic response of high-altitude tethered platforms and for the preliminary assessment of the technical feasibility of these systems.

Abstract
The study presented in this paper concerns the development of an algorithm, based on finite element analysis, for
the dynamic simulation of a tethered lighter-than-air balloon when subjected to operational conditions. The main
features of the algorithm are described, highlighting the advantages of this approach when performing dynamic
analysis. The input parameters considered in the method are derived from experimental and simulated data, which
are elaborated to obtain the static and dynamic atmospheric properties in terms of mean windspeed profile, discrete
gusts, and continuous turbulence. In particular, the algorithm is employed to perform a thorough analysis of a specific high-altitude tethered platform operating in a realistic design scenario. The dynamic behavior of the system is evaluated in terms of displacements and tether forces. The results, even though they are obtained for a specific example application, demonstrate the general viability of the algorithm proposed for the evaluation of the dynamic response of high-altitude tethered platforms and for the preliminary assessment of the technical feasibility of these systems.
