Документ Відкритий доступ Advanced Eddy Current Methods For Evaluating Aviation Components(Національний авіаційний університет, 2024-05) Lysenko, I.; Kuts, Y.; Mirchev, I.The presentation provides guidelines for conducting eddy current non-destructive testing on components made of Al-Mg-Si alloy, a popular material in the aerospace industry due to its high mechanical properties and good corrosion resistance. Several potential defects may exist in such components, including internal voids or blowholes, cracks, corrosion, and inhomogeneities in the material's structure. Internal voids can occur during manufacturing, reducing mechanical strength and potentially leading to failure. Cracks may form due to stress or mechanical influences and can propagate, causing component failure. Corrosion may develop on the surface when exposed to aggressive environments or high humidity, weakening the components. Inhomogeneities arising during manufacturing or thermal treatments can affect mechanical properties and lead to failures.Документ Відкритий доступ Analysis of non-destructive methods for the testing of the powder materials physical and mechanical characteristics(КПІ ім.

Ігоря Сікорського, 2019) Muraviov, OleksandrДокумент Відкритий доступ Investigation of frequency impact on the efficiency of automated eddy current testing of aluminum alloys(Національний авіаційний університет, 2024-05) Lysenko, I.; Uchanin, V.; Kuts, Y.; Aleksiev, A.In modern manufacturing, objects made from aluminum alloys are widely used in various industries such as automotive, aerospace, shipbuilding, construction, and others. The application of aluminum alloys is continuously expanding due to their lightness, strength, and corrosion resistance. During the operation of aluminum alloy structural elements, quality testing is crucial, especially for critical components in aerospace, marine, and construction structures. An important aspect of ensuring the quality and safety of such structures is the timely and effective detection of defects, such as cracks, fatigue assessment, and flaws in structural joints. For this purpose, various non-destructive testing methods are employed, among which eddy current testing (ECT) methods hold a significant place.Документ Відкритий доступ Lens image quality athermalization for infrared medical cameras(КПІ ім. Ігоря Сікорського, 2023) Muraviov, O. V.The article focuses on resolving the challenge of maintaining image quality in IR lenses of medical thermography cameras due to thermal instability, which can arise when these devices operate in environments with fluctuating temperatures. The paper provides a succinct analysis of the potential areas where thermography can be applied. The proposed solution involves utilizing the passive optical athermalization method to stabilize the characteristics of thermographic optical system.Документ Відкритий доступ Medical thermal imaging diagnostics: current problems and surgical application(КПІ ім. Ігоря Сікорського, 2024) Muraviov, O. V.; Dovbysh, I. O.Nowadays criteria of thermal imaging diagnostics for more than two hundred diseases and pathological conditions are developed and this list is constantly being replenished. One of the most important problems at cardiac surgical interventions is ischemic myocardial damage, since normal coronary perfusion is absent due to aorta clamping. For complete control over the temperature distribution using of infrared cameras is promising and innovative, that allows to get a highly informative image of temperature distribution on entire heart surface.Документ Відкритий доступ Modern laser rangefinding(КПІ ім.
