In this paper, we examine the possible realization of a new inflation family called "shaft inflation" by assuming the modified Chaplygin gas model and a tachyon scalar field. We also consider the special form of the dissipative coefficientφ 2 and calculate the various inflationary parameters in the scenario of strong and weak dissipative regimes. In order to examine the behavior of inflationary parameters, the n s -φ, n s -r , and n s -α s planes (where n s , α s , r , and φ represent the spectral index, its running, tensor-to-scalar ratio, and scalar field, respectively) are being developed, which lead to the constraints r < 0.11, n s = 0.96 ± 0.025, and α s = −0.019 ± 0.025. It is quite interesting that these results of the inflationary parameters are compatible with BICEP2, WMAP (7 + 9) and recent Planck data.
