WebSep 1, 2024 · In this paper, we have performed an experiment of inflating a cylindrical nematic balloon with an additional external load along the axial direction as shown in Fig. 1 (a) for a free-standing case. Our experiments show that soft elasticity of the nematic elastomer can lead to anomalous inflation behavior of the balloon, which is in significant … WebRubber airbags are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in a long cylindrical balloon shape. Ship launching or upgrading using marine airbags is an innovative ship launching technology. It overcomes the disadvantage of “end-on launching”, “side ship launching”, “float-out”. ...
