Aerospace and Mechanical Engineering2022<p>The Engine Air Particle Separator is considered to be the most important element for maintaining the performance of helicopter engines when operating in dusty air conditions. The intensity of erosion of the elements of the gas-air passage of the gas turbine engine depends on many factors: on the hardness and chemical composition of dust particles, on the fractional composition, sand concentration, engine operating condition etc.Therefore, the development of a method for selecting the optimal values of the Engine Air Particle Separator parameters is a complex multi-criteria and multi-factor task. The present document addresses the selection method of optimal values (geometric dimensions) of the Engine Air Particle Separator parameters in aviation gas turbine engines. The methodology includes six main steps. The choice of optimal values of the Engine Air Particle Separator geometrical parameters is accomplished taking into account three partial criteria for the Engine Air Particle Separator efficiency: the degree of air purification, pressure loss and mass. The Engine Air Particle Separator parameters are selected using the Pareto method. An example of choosing the optimal values of the geometric parameters of a cyclone Engine Air Particle Separator is considered.</p>Пылезащитное устройствопоказатели эффективности пылезащитного устройстваобобщённая функция целиПарето-оптимальное множествоParticle separatoroptimal parameters of a dust protection devicegeneralized target functionPareto optimal set[Stepanov G.Yu., Zitser I.M.
