The nonlinear kinetic model of cosmic ray (CR) acceleration in supernova remnants (SNRs) is used to describe the properties of the young remnants of SN 1006, Tycho's supernova, and Cassiop eia A in the Galaxy. The calculated expansion law and the radio-, X-ray and gamma-ray emissions produced by the accelerated CRs in these SNRs agree quite well with the observations, which in the case of Tycho's gamma-ray flux corresp ond to an upper limit. It is shown that the predicted pion-decay TeV gamma-rays from SN 1006, Cas A and Tycho dominate over the inverse Compton (IC) gamma-rays, generated by the CR electrons in the cosmic microwave background. It is also shown that the associated set of parameters is consistent with the idea that these SNRs are typical Galactic CR sources.
