Improving diagnostics and forecasting of the technical condition of aircraft structural elements by taking into account the impact of non-stationary gas flows

Abstract

This paper presents the results of a study of the effect of pulsating subsonic gas flow treatment on the corrosion resistance of structural metal materials used in aircraft structural elements. The disadvantage of even the most modern methods of increasing the structural strength of metal materials is an insufficient increase in corrosion resistance. An urgent task is to develop methods for increasing the corrosion resistance of aircraft structural elements throughout their volume without additional alloying, which not only increases the cost of the product material, but also, often, makes it less producible, which can be used during the restoration of both aviation and airfield equipment. The article describes a method developed by the authors to increase corrosion resistance using pulsed subsonic gas flows. The data obtained as a result of the conducted research will allow more effective control of the corrosion condition of aircraft by non-destructive methods, as well as increase the accuracy of forecasting the technical condition.
