(Материалы и методы) Провели исследования, опираясь на основные уравнения сохранении энергии и массы в прикладной газовой динамике: уравнение Бернулли, уравнение неразрывности потока. Использовали методику оценки распределения давлений в воздуховоде вентиляторов и аналитические выражения расчета газовой струи, а также стандарты для установления универсальных параметров и размеров вентиляторов и распылителей жидкости. (Результаты и обсуждение) Теоретически рассчитали основные параметры: расход воздуха для покрытия заданного объема кроны – 11,28 метра кубического в секунду; расход воздуха одним вентилятором – 1,88 метра кубического в секунду; скорость потока воздуха при выходе из вентилятора – 17,9 метра в секунду; полное давление, развиваемое вентилятором – 192,25 паскаля; мощность, необходимая для привода одного вентилятора – 0,170 киловатта; установочная мощность двигателя вентилятора – 0,204 киловатта; длину начального участка струи – 1,53 метров; осевую скорость струи – 13,6 метра в секунду, расход воздуха – 12,84 метра кубического в секунду, диаметр круглой струи 1,58 метра. (Выводы) Обосновали технологическую схему мультивентиляторного опрыскивателя. Предложили расчетные уравнения, устанавливающие характер распределения статического, динамического и полного давления в различных сечениях вентилятора опрыскивателя. Представили алгоритм расчета параметров модуля опрыскивателя.

As new technologies emerge, the demands placed on spraying ventilation systems are also evolving. (Research purpose) The objective of this research is to establish the design and technological speciﬁcations of the multi-fan sprayer module. (Materials and methods) The research is grounded on fundamental equations of energy and mass conservation in the ﬁeld of applied gas dynamics, speciﬁcally the Bernoulli equation and the ﬂow continuity equation. To analyze the pressure distribution within the fan duct and calculate the gas jet, a speciﬁc methodology was employed in this research. Additionally, the research utilizes analytical expressions and industry standards to determine universal parameters and dimensions of fans and liquid atomizers. (Results and discussion) Theoretical calculations were performed to determine the main parameters. The results are as follows: the air consumption required to cover a given crown volume is 11.28 cubic meters per second; the air consumption by one fan is 1.88 cubic meters per second; the air ﬂow rate at the fan outlet reaches 17.9 meters per second; pressure generated by the fan is 192.25 pascals; power required to drive one fan is 0.170 kilowatts; the installed power of the fan motor is 0.204 kilowatts; the jet initial section length is 1.53 meters; the axial jet velocity is 13.6 meters per second; the air consumption is 12.84 cubic meters per second; the round jet diameter is 1.58 meters. (Conclusions) The technological scheme of a multi-fan sprayer has been developed and justiﬁed. Calculation equations have been proposed to determine the distribution of static, dynamic, and total pressure in diﬀerent sections of the sprayer fan.  An algorithm for calculating the parameters of the sprayer module has been presented. The numerical values of the parameters for the multi-fan sprayer module have been determined for speciﬁc operating conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мультивентиляторный опрыскиватель</kwd><kwd>аэродинамические характеристики</kwd><kwd>расчетные уравнения</kwd><kwd>обоснование</kwd><kwd>параметры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multi-fan sprayer</kwd><kwd>aerodynamic characteristics</kwd><kwd>calculation equations</kwd><kwd>substantiation</kwd><kwd>parameters</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">Куликов И.М., Утков Ю.А., Бычков В.В.
