We study group-theoretical solutions to the dynamic equations of polytropic gas. 95 invariant submodels are considered. In a number of cases the factorsystems can be integrated, and several submodels admit constructing partial solutions. This result is applicable in gas dynamics, aerodynamics, and physics of atmosphere.
Keywords: dynamics of polytropic gas, algebra of symmetry.
Mots-clés : invariant solution
