A series of simulation calculations is carried out in a software package based on multiphysical modeling methods STAR-CCM+. Based on their results, the model of the existing ejection water pumping system of a serial amphibious vehicle is verified and the high convergence of the data obtained by modeling is confirmed. А model of the ejection water pumping system of a promising amphibious vehicle is being developed. The influence of the location of a row of holes in the pressure pipe of a water-jet propulsion unit, the number of rows, the number of holes in each of them and their diameters, the chamfer angle at the inlet section of the hole, the inlet and outlet diameters of the holes on the performance of the ejection water pumping system is considered and analyzed. Based on the results of a series of simulation calculations, the parameters were determined, allowing the highest productivity of the ejection water pumping system. Productivity is increased by 1,29 times compared to the original version, and the resistance of the suction path is reduced by 1,97 times. Tests of an improved ejection water pumping system is confirmed the simulation results.</p></abstract><trans-abstract xml:lang="ru"><p>Усовершенствована конструкция эжекционной системы водооткачки перспективной амфибийной машины. Проведена серия симуляционных расчетов в программном пакете на основе методов мультифизического моделирования STAR-CCM+, по результатам верифицируется модель существующей эжекционной системы водооткачки серийной амфибийной машины, подтверждается высокая сходимость данных, полученных путем моделирования. Разрабатывается модель эжекционной системы водооткачки перспективной амфибийной машины. Рассматривается и анализируется влияние местоположения ряда отверстий в напорном патрубке водометного движителя, числа рядов, количества отверстий в каждом из них и их диаметров, угла фаски на входном участке отверстия, входного и выходного диаметров отверстий на производительность эжекционной системы водооткачки. По итогам серии симуляционных расчетов определены параметры, позволяющие обеспечить наибольшую производительность системы эжекционной водооткачки. Производительность по сравнению с исходным вариантом увеличена в 1,29 раз, а сопротивление трассы всасывания снижено в 1,97 раз. Испытания усовершенствованной эжекционной системы водооткачки подтверждают результаты моделирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>water-jet propulsion</kwd><kwd>water pumping</kwd><kwd>dewatering</kwd><kwd>ejection effect</kwd><kwd>amphibious vehicle</kwd><kwd>simulation</kwd><kwd>CFD</kwd><kwd>modeling</kwd><kwd>verification</kwd><kwd>experimental research</kwd><kwd>prediction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>водометный движитель</kwd><kwd>водооткачка</kwd><kwd>водоотлив</kwd><kwd>эффект эжекции</kwd><kwd>амфибийная машина</kwd><kwd>симуляция</kwd><kwd>CFD</kwd><kwd>моделирование</kwd><kwd>верификация</kwd><kwd>экспериментальное исследование</kwd><kwd>прогнозирование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Степанов, А.П.
