The formation of the toroidal and jet‐like structures in the central part of the Crab Nebula is explained in the framework of Kennel & Coroniti theory. The only new element introduced by us in this theory is the initial anisotropy of the energy flux in the wind. We estimate the X‐ray surface brightness of the Crab Nebula from the region of interaction of this wind with the interstellar medium and compare it with observations.
