DEVELOPMENT OF A METHODOLOGY FOR DETERMINING THE OPTIMAL GEOMETRIC PARAMETERS OF A CONFUSER IN THE COOLING SYSTEM OF A HELICOPTER POWER PLANT

Relevance This article discusses the possibility of increasing the heat transfer of radiators by installing a confuser in the receiver space. This will allow for more efficient distribution of air flows, as well as increase their flow rate, which, in turn, will lead to an increase in oil heat transfer to the environment by reducing the flow section. The relevance lies in the fact that the solution proposed in it allows to improve the heat distribution inside the radiator, increase the efficiency of heat exchange and lower the oil temperature, which helps to increase the service life of the equipment and reduce maintenance and repair costs. Aim of research The aim of the study is to develop a methodology that will allow determining the optimal geometric parameters of the confuser in the cooling system of the helicopter's power plant. This will increase its efficiency and reduce energy consumption. Within the framework of this study, the following tasks are to be performed: to develop a structural diagram of the data acquisition unit, to modernize the receiver, to develop a functional diagram of the asynchronous motor control unit. Results Thus, the development of a methodology that will help determine the optimal confuser geometry for the cooling system of a helicopter power plant is an urgent and important task. The proposed technique will make it possible to efficiently distribute air flows and increase the heat transfer coefficient of radiators. This, in turn, will improve oil cooling and increase the reliability of the power plant. Further research in this area may be aimed at experimentally confirming the effectiveness of the proposed technique and optimizing the design of the confuser, taking into account the specific operating conditions of the helicopter.
