Description
Summary:With the development of aircraft electrification, the problem of thermal management has become increasingly prominent. It is necessary to propose a new aircraft energy management method to satisfy the needs of aircraft thermal management while maintaining high efficiency. This study addresses a compressed carbon dioxide energy storage system applied in aircraft energy management. Especially, this is the first time carbon dioxide has been used for aircraft energy storage. In this system, carbon dioxide can be used as a cold source to dissipate heat for the equipment. The system can also provide electrical energy for avionics, achieving combined cooling and power generation with a compact structure. Moreover, the energy storage unit increases the flexibility of the system. In this paper, the novel system is modeled and simulated. Results indicate that the system can operate stably to satisfy energy demand. The energy utilization efficiency of the system is 69% under design conditions. When the energy is stored first and then released, the exergy efficiency of the system can reach 81.66%, which has good economic benefits. The system is efficient, compact and flexible. It realizes the cascade utilization of energy while working, and simultaneously meets the energy requirements of cold, heat and electricity.
