摘要

Achieving high requirements for the safety and comfort of passengers and crew of modern aircraft requires the improvement of environment control systems, which are designed to create and maintain standardized air parameters (pressure, temperature, relative humidity, air velocity, etc.) in the pressure chamber.To solve such problems in joint hydraulic and thermal calculations, special software systems are used to replace real complex systems and structures with structural diagrams of the corresponding mathematical models. However, it should be borne in mind that one-dimensional software systems cannot take into account the effects of the distribution of temperature and air pressure, taking into account the three-dimensional geometry of the passenger compartment or cockpit. Stagnation zones or deterioration of comfort conditions due to the uneven distribution of air parameters near the passenger are also possible. To solve the problem of estimating the distribution of air parameters near passengers, computational fluid dynamics methods (LOGOS, ANSYS CFX, Fluent, Star CCM+) are used to obtain a spatial distribution of the desired parameters and improve passenger comfort. Thus, to improve the quality of calculations and optimize the design of the environment control system, the interaction of one-dimensional and three-dimensional software systems is required. To implement the interaction of software systems, an example of data exchange (flow rate, temperature) was considered to maintain a given temperature in the cabin. In the SimInTech software package, a model of an air-cooling installation with the ability to change parameters was implemented and automatic equipment was prescribed to set the flight mode and operation algorithms of the dampers. In the three-dimensional software complex LOGOS, a calculation model of the cabin was prepared. The calculation of the cabin takes into account heat from passengers and changes in the parameters of moist air. The interaction of software systems has shown the possibility of increasing the speed and quality of calculations by detailing the results in the areas of interest by applying a three-dimensional code and reducing the calculation time of complex schemes by using a one-dimensional code. The solution to this problem will improve the quality of the calculations, which is necessary to optimize the design of onboard aircraft systems.
