  Tachyon inflationary universe model on the brane in the context of warm
inflation is studied. In slow-roll approximation and in longitudinal gauge, we
find the primoradial perturbation spectrums for this scenario. We also present
the general expressions of the tensor-scalar ratio, scalar spectral index and
its running. We develop our model by using exponential potential, the
characteristics of this model are calculated in great details. We also study
our model in the context of intermediate (where scale factor expands as:
$a=a_0\exp(At^f)$) and logamediate (where the scale factor expands as:
$a=a_0\exp(A[\ln t]^{\nu})$) models of inflation. In these two sectors,
dissipative parameter is considered as a constant parameter and a function of
tachyon field. Our model is compatible with observational data. The parameters
of the model are restricted by recent observational data from the nine-year
Wilkinson microwave anisotropy probe (WMAP9) and Planck data.
