Abstract
The goal of this work was to test the practicability of using a device that provides airflow into the Laval nozzle channel to enable the application of metal coating by cold spraying. A turbine with an integrated Laval nozzle at the outlet was considered as a device to provide airflow into the Laval nozzle channel. The authors describe the equipment used in the calculations and the experimental study, the process of gas- dynamic calculation of the output velocity of the airflow injected by the turbine impeller and the results of this calculation with precise indices. As a result, functional dependences of the indicators that provide the possibility of using the turbine as a source of airflow have been obtained, and a conclusion about the inexpediency of using a turbine with an integrated Laval nozzle at the outlet to provide the possibility of metal coating by cold spraying has been formed.
