Контроль качества топлива – многопараметровая задача, включающая контроль содержания свободной влаги. Регламентирующие документы устанавливают содержание свободной воды не более 0,0015 % масс. Разработан прямой электрометрический микроволновый резонаторный метод контроля свободной влаги в авиационных топливах. Метод заключается в измерении характеристик резонанса цилиндрического объёмного резонатора. При этом на твёрдой диэлектрической поверхности внутри резонатора находятся капли влаги, прижатые тонкой пластиной. Вследствие этого резко повышаются диэлектрические потери. Проведены аналитический и экспериментальный анализы метода. Обоснован диапазон контроля 0,5–30 мкл абсолютного объёма влаги авиационных топлив с максимальной погрешностью не более 25 %. Чувствительность предложенного метода контроля СВЧ-потерь в каплях свободной влаги, трансформированных в тонкий слой прижатием тонкой пластиной, на порядок больше чувствительности метода контроля СВЧ-потерь в каплях влаги на твёрдой поверхности в резонаторе. Предложенный метод может быть положен в основу создания приборов контроля свободной влаги авиационных топлив в условиях аэродрома и лаборатории. Показано направление развития метода.</p></abstract><trans-abstract xml:lang="en"><p>One of the conditions for ensuring the safety of air transport operation is the quality of aviation fuel refueled in aircraft. Fuel quality control is a multi-parameter task that includes monitoring the free moisture content. Regulatory documents establish the content of free water no more than 0.0015% by weight. It is developed a direct electrometric microwave resonance method for controlling free moisture in aviation fuels, which consists in changing the shape of the water drops by pressing them on a solid surface inside a cylindrical cavity resonator. This can dramatically increase dielectric losses. Analytical and experimental analysis of the proposed method is carried out. The control range from 0,5 to 30 μl of absolute volume of moisture in aviation fuels with a maximum error of not morethan 25 % is justified The sensitivity of the proposed method for monitoring microwave losses in free moisture drops transformed into a thin layer by pressing is an order of magnitude greater than the sensitivity of the method for monitoring microwave losses in moisture drops on a solid surface in a resonator. The proposed method can be used as a basis for the development of devices for monitoring the free moisture of aviation fuels in the conditions of the airfield and laboratory. The direction of development of the method is shown.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цилиндрический объёмный резонатор</kwd><kwd>влага</kwd><kwd>электрическое поле</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cylindrical cavity resonator</kwd><kwd>humidity</kwd><kwd>electric field.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Viktorov V.
