摘要：

We study the original Chaplygin gas model in the context of Randall-Sundrum type-II braneworld with a hyperbolic potential. We consider the Chaplygin gas as a candidate for inflation by using the latest data release from Planck 2015. We found that the various inflationary spectrum parameters n(s), r and depend only on the number of e-folds. The compatibility of these parameters with the last measurement of Planck is realized with large values of N. In this context, a suitable observational central value of n(s) = 0.965 is obtained in the case of the original Chaplygin gas and a hyperbolic potential.
