The report is devoted to the results of acoustic emission (AE) diagnostics of vehicles obtained by the Rostov school of AE over the past 45 years. Over the years, we have carried out a series of studies both on the AE itself and on its practical application for the diagnosis of mission-critical products, including objects of aviation and rocket and space transport. The fundamentally new interdisciplinary approach proposed by us, which consists in using the kinetic concept of strength, the Poisson model of the defect formation process, and the experimentally discovered physical and mechanical features of the AE phenomenon (including the statistical parameters of the random AE process that are stable due to a number of limit theorems) is described. Practical application of the obtained results is shown on the examples of AE diagnostics of the strength of structural elements of the Russian heavy transport helicopter and the Russian Shuttle Buran.
