Mathematical Modeling of the No-bleed Air Conditioning System for an Advanced Passenger Aircraft

At the moment, the most perspective development direction of the aviation industry is the creation of a more electric aircraft and in this case, there are no bleed systems that taking air from the engine, which is necessary to ensure the operation of the air conditioning system and ice protection system. This article discusses the possibility of using no bleed systems and calculating the required characteristics using mathematical modeling. Simulation results show the operation modes of a centrifugal compressor and using to compare two versions of the air-cooling units in case of rotational speed of compressor is limited. The simulation results presented in this article can be used in the design of compressors for advanced electric air conditioning systems.
