review text: In this article, two new cosmological solutions to Einstein's field equation are presented. The metric is assumed to be of Bianchi type II, and the matter source is a (non-perfect) fluid with or without additional radiation component. The pressure of the fluid is anisotropic and its flow lines are twisting, expanding and non-geodesic. In the case with additional radiation field, the scale factor is of the form \(R(t) = R_0 e^{Ht}\), where \(R_0\) and \(H\) are constants, so that the solution can be interpreted as a model for an inflationary phase of the universe.
