  In ultra-relativistic collisions of heavy ions, the strongly interacting
Quark Gluon Plasma (sQGP) is created. The fluid nature of the sQGP was one of
the important discoveries of high energy heavy ion physics in the last decades.
Henceforth the explosion of this matter may be described by hydrodynamical
models. Besides numerical simulations, it is important to study the analytic
solutions of the equations of hydrodynamics, as these enable us to understand
the connection of the final and initial states better. In this paper we present
a perturbative, accelerating solution of relativistic hydrodynamics, on top of
a known class of solutions describing Hubble-expansion. We describe the
properties of this class of perturbative solutions, and investigate a few
selected solutions in detail.
