Determination was made of the length of the first region of instability in a gas jet, flowing from a channel under conditions of underexpansion, for the purpose of obtaining recommendations for the magnitude of clearance in an ultrasonic generator of a low-differential injector. The solution of the gas-dynamical problem is made in the assumption on the correctness of the equation of gas dynamics of a plane potential flow of gas for the case of flow in radial clearance. Results are given of experiments on the study of the fineness of liquid atomization by an injector with an ultrasonic generator, conducted while taking into account recommendations of the author related to the length of the region of instability.
