“…Consequently, the dry weight can be calculated from Equation (8), and the wet weight from Equation ( 9), considering that HEXs are constructed from aluminum. It is important to calculate both, as wet weight includes the coolant, with the assumption that 25% of porosity accounts for the liquid coolant channels.…”

“…On a parallel configuration either or both the battery powered motor and the gas turbine can provide propulsive power. Parallel hybrid configurations have been extensively studied in the literature, with applications on commuter and regional classes [6][7][8][9][10][11]. Their apparent benefits include easier implementation, reduced complexity and costs, compared to the other variants.…”

“…As the majority of research focuses mainly on parallel-hybrid configurations [8][9][10][11], the motivation of this work is to explore the preliminary design of a TMS considering a series propulsion architecture. Different thermal management architectures are examined, by altering the number of the system's heat exchangers.…”

The current paper is focused on the conceptual design of a thermal management system with a liquid working medium for a commuter hybrid-electric aircraft, featuring a series propulsion configuration. Regarding the system’s architecture, parametric analyses are conducted, by altering the number of heat exchangers. To clarify, a centralised and a decentralised thermal management system architecture are examined. Furthermore, a computational model calculates the temperatures during the system’s operation and the required coolant mass flows to sufficiently cool all the compartments. Subsequently, the required heat exchanger surface is determined and the weight of each compartment that comprises the thermal management system can be calculated. It is worth noting, that the compartments’ cold plate weight is integrated. The results indicate that the decentralised configuration results in lower temperature fields for all components compared to the centralised configuration. However, the latter weighs 32.2% lower at 158.22kg while the decentralised configuration weighs 233.48kg.

This paper discusses the development of mesh jet devices for hybrid turbines, including developing Euler's ideas, and considers a new patented version of a mesh jet device designed to create guiding devices for turbines. The research methods are based on simulations using CFD and additive technologies. An intermediate conclusion is that a new scientific direction for the study and creation of mesh jet control systems has been formed as part of developing Euler's ideas. Calculation methods showed possible improvements in the performance of jet devices, including the use of curved tubes proposed by Euler to create turbines. This study shows that at the nozzle or mixing chamber outlet, the jet can deflect by an angle from +180° to -180° within the geometric sphere. This study also shows that the scientific groundwork prepared by Euler is not yet fully understood. The ongoing research mainly focuses on creating multi-mode jet devices designed for control systems for mesh turbomachines. Here, power consumption from an external source can be reduced to save energy. Some results of ongoing studies can also be applied in other industries (for example, when creating hybrid propulsion systems or propulsors). The scientific novelty of this work consists of improving the design methodology of jet machinery and turbomachines. Doi: 10.28991/CEJ-2022-08-12-06 Full Text: PDF
