In order to find some fundamental effects and new applications of tapered pneumatic transmission lines, their dynamic characteristics are investigated, which is based on step pressure inputs. Various wave phenomena in a compound system of some tapered tubes, e. g. in the combination of tapered and linear tubes, in a tapered tube with an arbitrary cross-section, are theoretically and experimentally studied. The pressure histories are characterized by some dimensionless parameters, for example, which indicate the tapered effect of a tube, the effect of viscosity of a gas, the effect of capacity of a tank and so on. The period of pressure wave and the attenuation of pressure wave are largely influenced by these parameters.
