Разработана цепная математическая модель линейного импульсного электромеханического преобразователя (ЛИЭП) электродинамического типа. Получены рекуррентные соотношения для расчета взаимосвязанных электромагнитных, механических и тепловых процессов. Установлено, что при увеличении толщины квадратной медной шины катушек индуктора и якоря от 1,0 до 2,5 мм увеличиваются амплитуда и величина импульса электродинамических усилий (ЭДУ). Максимальная скорость якоря наибольшая у ЛИЭП, катушки индуктора и якоря которого намотаны шиной толщиной1,5 мм. Наибольшее значение КПД у ЛИЭП, катушки которого намотаны шиной толщиной2,0 мм. При увеличении количества слоев шины катушки индуктора амплитуда ЭДУ уменьшается существенно, а величина импульса ЭДУ– незначительно. Вследствие этого снижаются максимальная скорость якоря, КПД и превышения температуры катушек. Наибольшая амплитуда ЭДУ реализуется в ЛИЭП при минимальном количестве слоев шин катушек индуктора и якоря, а наибольшая величина импульса ЭДУ возникает при максимальном их количестве. При этом наибольшие значения амплитуды и импульса ЭДУ возникают при условии, когда количество слоев шины катушек одинаковы. Наибольший КПД(21,82 %) реализуется в ЛИЭП, у которого катушки индуктора и якоря намотаны в четыре слоя квадратной шины толщиной 2,0 мм. На базе ЛИЭП электродинамического типа была изготовлена и испытана модель катапульты для запуска беспилотного летательного аппарата.
The aim of the paper is to study the influence of geometrical parameters, namely, the number of layers and the cross section of the copper tire of the inductor and the armature coils on the power and speed indicators of a linear pulse electromechanical converter (LPEC) of an electrodynamic type. Methodology. On the basis of the developed chain mathematical model, recurrent relations are obtained for the calculation of interconnected electromagnetic, mechanical and thermal processes of LPEC of an electrodynamic type.The effect of the thickness of a square copper tire and the number of its layers in the inductor and armature coils on the characteristics and characteristics of electrodynamic LPEC is investigated. It is these parameters that determine the number of turns and the axial height of the coils with limited radial dimen-sions. Results. The influence of the geometrical parameters of the inductor and the armature coils with limited radial dimensions on the electrical and mechanical characteristics of LPEC of an electrodynamic type is established. It has been established that with an increase in the thickness of a rectangular cross-section of copper tire from 1 to 2.5 mm, an increase in the amplitude and pulse of electrodynamic forces (EF) occurs. However, the maximum speed of the armature is the highest at LPEC wound with a 1.5 mm thick tire.The highest efficiency value is demonstrated by LPEC, in which the inductor and armature coils are wound with a 2 mm thick tire. With an increase in the number of layers of the inductor coil tire, the amplitude of the EF decreases significantly, and the magnitude of the EF pulse decreases slightly. As a result, the maximum armature speed, efficiency and temperature rise of the coils are reduced. Originality. It is established that the largest amplitude of the EF is realized in LPEC with the minimum number of layers of tires of the inductor and armature coils. The largest value of the pulse EF occurs when the maximum number of layers of the inductor and the armature. In this case, the largest values of the amplitude and pulse of the EF occur under the condition that the number of tire layers of the inductor and the armature coils are the same. Practical value.It has been established that the greatest efficiency 21.82 % is realized in LPEC, in which the number of tire layers is 2 mm thick with inductor and armature coils are 4. A catapult model for launching an unmanned aerial vehicle was made and tested on the basis of LPEC of an electrodynamic type.
