Three component model of cosmic ray spectra from 100 GeV up to 100 PeV

A model to describe cosmic ray spectra in the energy region from 100 GeV up to 100 PeV is suggested. It bases on the preposition that Galactic cosmic ray flux is a mixture of fluxes, accelerated by shocks from nova and supernova explosions of different types. We analyze recent experimental data on cosmic ray spectra obtained in direct measurements above the atmosphere and data obtained with ground EAS arrays. It is shown that the model of three classes of cosmic ray sources describes direct experimental data on cosmic ray elemental spectra and gives a smooth transition from all particle spectrum measured in the direct experiments to all particle spectrum measured in EAS
