Abstract : A plane, steady, laminar, and adiabatic flow of an ideal gas in a Laval nozzle is studied. Such a flow is described by the Chaplygin equation for any practical important distance from the sound line. The Chaplygin equation is sought as an infinite series in which the first member is the Tricomi equation. Unlike the straight problem in the nozzle, when for the given walls the flow inside it is sought, a semireverse problem has to be solved; the distribution of gas velocity passing beyond the speed of sound along the axis of symmetry, considered as the zero line of the flow in the form of ananalytical function from the coordinate. The flow outside the axis is sought. Two fixed lines of the flow are assumed as the walls of nozzle. (Author)
