Исследование устойчивости авиационного двигателя ПД-14 к воздействию вулканического пепла // Вестник УГАТУ. 2022. Т. 26. Вып. 96. № 2.

Впервые представлены результаты испытаний российского авиационного двигателя типа ПД-14 при попадании в его газовоздушный тракт вулканического пепла. Испытания ПД-14 разработки АО «ОДК-Авиадвигатель» проводили в условиях закрытого наземного стенда Ц-17Т ФАУ «ЦИАМ им. П. И. Баранова» согласно требованиям европейского агентства по авиационной безопасности EASA. В качестве вулканического пепла использовали натуральный пепел современных извержений камчатского вулкана Шивелуч. Показано, что попадание пепла в двигатель ПД-14 с максимально допустимой в Европе концентрацией 4 мг/м3 в течение одного часа не приводит к изменению тяговых характеристик ПД-14 и возникновению нежелательных последствий. Особое внимание уделено воздействию вулканического пепла на камеру сгорания и турбину двигателя. Приведены данные рентгеноспектрального анализа стекловидных отложений пепла на элементах турбины. Проведен численный расчет модельной области генерации стекловидных отложений пепла Шивелучa в газовоздушном тракте двигателя ПД-14.

На основании данных полевых исследований разных лет рассмотрен макро- и микрокомпонентный состав вод оз. Зеленое в кратере Троицкого активного вулкана Малый Семячик. Показано, что озеро содержит ультракислую (pH < 1) воду сульфатно-хлоридного состава с минерализацией от 8 до 42 г/л в зависимости от состояния вулкана. Анионный состав озера формируется за счет поступления и последующего растворения кислых вулканических газов в водоносном горизонте, располагающемся непосредственно под озером. Катионный состав воды обусловлен практически конгруэнтным растворением вмещающих пород. После длительного периода покоя, в 2008 г. начался новый этап гидротермальной активизации вулкана, продолжающийся в настоящее время. На фоне постоянно повышающегося объема наблюдается рост концентраций основных макрокомпонентов (SO4, Cl, Al, Fe) и минерализации воды в целом.

Based on the data of field studies in different years, the macro- and microcomponent composition of the waters of the Zelenoe Lake in the crater of the Troitsky active volcano Maly Semyachik were considered. It is shown that the lake contains ultra-acidic (pH < 1) water of sulfate-chloride composition with mineralization from 8 to 42 g/L, depending on the state of the volcano. The anion composition of the lake is formed by the inflow and subsequent dissolution of acidic volcanic gases in the aquifer located directly under the lake. The cation composition of water is formed by the almost congruent dissolution of the host rocks. After a long period of dormancy, in 2008 a new stage of hydrothermal activation of the volcano began. The activity is ongoing. Against the background of a constantly increasing volume, there is an increase in the concentrations of the main macro components (SO4, Cl, Al, Fe) and in the salinity of water in general.

There are 30 active volcanoes in the Kamchatka, and several of them are continuously active. In the XX-XXI centuries 17 volcanoes of Kamchatka erupted. During this time, 183 volcanic eruptions occurred, including three catastrophic eruptions (Ksudach, 1907; Bezymianny, 1956; Sheveluch, 1964). Strong explosive eruptions of volcanoes were the most dangerous for human society because they produce in a few hours or days to the atmosphere till 2-3 cubic kilometers of volcanic products. Ash plumes and the clouds, depending on the power of the eruptions, the strength and wind speed, to traveled thousands of kilometers from the volcanoes for several days. Any territory of the Kamchatka Peninsula has repeatedly been exposed to ash falls, the thickness of ash in settlements was from less than 1 mm to 4-5 cm. Strong explosive eruptions of volcanoes Sheveluch, Klyuchevskoy, Bezymianny, Kizimen, Karymsky, Zhupanovsky, Avachinsky, Kambalny were the most dangerous for air travel not only over Kamchatka, but also hundreds of kilometers away from the peninsula.
The strong explosive and effusive eruptions of Sheveluch, Klyuchevskoy, Bezymianny, Kizimen and the other were often accompanied by the formation of hot mud flows (lahars), which sometimes disrupted transport communications (roads, bridges) of nearby settlements.
Scientists of KVERT monitor Kamchatkan volcanoes since 1993. Thanks to satellite monitoring of volcanoes carried out by KVERT, several explosive eruptions were predicted in the XXI century, and early warnings were made to the population about possible ashfalls in settlements and about hazard to aviation.

The work is devoted to the activity analysis of Kamchatka and the Kuril Islands volcanoes in 2019-2020.The activity of the volcanoes was estimated based on the processing of data from daily satellite monitoring carried out using the information system “Remote monitoring of Kamchatkan and the Kuriles volcanoes activity (VolSatView)”. The activity of the Kamchatka and the Kuril Islands volcanoes considered based on the analysis of their thermal anomalies. Analysis of the characteristics of thermal anomalies over volcanoes was carried out in KVERT IS. Analysis of the temperature of thermal anomalies of volcanoes in the Kuril - Kamchatka region in 2019-2020 shows a significantly higher activity of the Kamchatka volcanoes in comparison with the Kuril volcanoes.

Geometric estimation of volcanic eruption column height from GOES-R near-limb imagery – Part 1: Methodology // Atmospheric Chemistry and Physics. 2021. Vol. 21. Vol. 16.

A geometric technique is introduced to estimate the height of volcanic eruption columns using the generally discarded near-limb portion of geostationary imagery. Such oblique observations facilitate a height-by-angle estimation method by offering close-to-orthogonal side views of eruption columns protruding from the Earth ellipsoid. Coverage is restricted to daytime point estimates in the immediate vicinity of the vent, which nevertheless can provide complementary constraints on source conditions for the modeling of near-field plume evolution. The technique is best suited to strong eruption columns with minimal tilting in the radial direction. For weak eruptions with severely bent plumes or eruptions with expanded umbrella clouds the radial tilt/expansion has to be corrected for either visually or using ancillary wind profiles. Validation on a large set of mountain peaks indicates a typical height uncertainty of ±500 m for near-vertical eruption columns, which compares favorably with the accuracy of the common temperature method.

In a companion paper (Horváth et al., 2021), we introduced a new technique to estimate volcanic eruption column height from extremely oblique near-limb geostationary views. The current paper demonstrates and validates the technique in a number of recent eruptions, ranging from ones with weak columnar plumes to subplinian events with massive umbrella clouds and overshooting tops that penetrate the stratosphere. Due to its purely geometric nature, the new method is shown to be unaffected by the limitations of the traditional brightness temperature method, such as height underestimation in subpixel and semitransparent plumes, ambiguous solutions near the tropopause temperature inversion, or the lack of solutions in undercooled plumes. The side view height estimates were in good agreement with plume heights derived from ground-based video and satellite stereo observations, suggesting they can be a useful complement to established techniques.
