description: This work is devoted to modeling hydrodynamic jets with an initial Lorentz factor of G = 5 using the FLASH code for numerical calculations in the field of hydrodynamics. The jet model was developed and simulations of two types of jets were launched with a full energy release of E = 3 * 10^51 erg and E = 10^52 erg for different times of activity of the central jet engine. The simulation results were studied: the dependence of the time of the breakout of the starshell on the activity time was obtained for both jet models, the plasma flow profiles were constructed (the dependence of the cumulative energy distribution on the Lorentz factor in the jet), and the radial profiles of the Lorentz factor in the jet were constructed. Based on the results, 3 possible ways of developing a supernova were formed, in which a jet is developing: a successful gamma-ray burst, a relativistic supernova, and a common supernova. Modeling has shown that a low-density jet can produce ultrarelativistic gas flows at certain times of activity of the central jet engine.
