Influence of Non-stationary Subsonic Air Flows on the Properties of Materials of Structural Elements of Aviation Equipment

The strengthening technologies currently used are not capable of providing a comprehensive increase in the mechanical properties of materials of aircraft structural elements. The processing technologies presented in the article based on pulsating air flows are capable of providing high values of structural strength. In the course of the research, the dependences of the mechanical properties of aircraft structural elements on the time of exposure to a pulsating subsonic air flow were established and the speed of the pulsating air flow acting on the product were found. The technologies developed by the authors to improve the mechanical properties of aircraft parts using the influence of pulsating subsonic air flows are described, the optimal processing time is found. The developed processing methods based on non-stationary air flows make it possible to provide a comprehensive increase in the mechanical properties of aircraft structural elements and to refine the forecast of the technical condition of aircraft components and parts that are affected by air flows during operation.
