Load-Carrying Ability and Application of Composite Materials Air Cushion in the Aerostat

Abstract:

The applications of air cushions are briefly reviewed in airships and tethered aerostats. The stress distributions of air cushions are simulated by finite element analysis software according to its load-carrying characteristics. Three kinds of interlayer forms are proposed and simulated thereafter. A best form of interlayer has been obtained via comparing the different analyzing results. In addition, an empirical formula is proposed for the differential pressures and load at the top of the air cushions, with experiments in which two kinds of air cushions are designed and their load carrying abilities are evaluated. Some advices are then provided for the designing and using of air cushions at the end of this paper.
