In this paper, the author proved the existence and uniqueness of a steady solution of the compressible axisymmetric jet problem. The problem was described within the formulation of irrotational flow, and it was proved that the jet problem and the previously examined variational problem are equivalent. Problems of the collision of two jets and jet impinging on a wall were also discussed. It should be mentioned that the corresponding two-dimensional problem has been studied before. It is also interesting to learn how this problem was evolved from a shape-charged device.
