  The discovery of the almost perfect fluid like nature of the strongly
interacting quark-gluon plasma was one of the most important discoveries of
heavy-ion physics in recent decades. The experimental results are well
described by hydrodynamical models. Most of these models are numerical
simulations, however the analytic solutions are also important in understanding
the time evolution of the quark-gluon plasma created in the heavy-ion
collisions. Here we present a perturbative, accelerating solution on top of a
known solution, the relativistic Hubble flow. We describe the perturbative
class of solutions, and calculate a few observables for a selected solution.
