  In this paper we study the Chaplygin gas model as a candidate for inflation
in the framework of the Randall Sundrum type-II braneworld model. We consider
the original and generalized Chaplygin gas model in the presence of monomial
potential. The inflationary spectrum perturbation parameters are reformulated
and evaluated in the high-energy limit and we found that they depend on several
parameters. We also showed that these perturbation parameters are widely
compatible with the recent Planck data for a particular choice of the
parameters space of the model. A suitable observational central value of
$n_{s}\simeq $ $0.965$ is also obtained in the case of original and generalized
Chaplygin gas.
