民用飞机空调系统性能仿真与燃油代偿损失研究
Performance simulation and fuel penalty investigation of civil aircraft air conditioning systems
摘要
Abstract
The air conditioning system in civil aircraft provides a comfortable thermal environment for the cabin,serving as a critical system to ensure the health and safety of passengers.Currently,most civil aircraft utilize a three-stage pressure-boosting high-pressure water removal system,which employs engine bleed air as the heat source and ram air as the cooling source,leading to significant fuel penalty losses.To analyze the economics of civil aircraft air conditioning systems,this paper establishes a dynamic simulation model of aircraft air conditioning system and presents a method for analyzing fuel penalty losses.The operating parameters of the system are calculated based on dynamic models and algorithms for key components such as air cycle machines and heat exchangers,combined with engine performance maps to obtain specific fuel consumption,thereby achieving the performance simulation of the air conditioning system and the analysis of fuel penalty losses.The results show that the bleed air used by the air conditioning system has a substantial impact on the system's fuel penalty losses.At a cruising altitude of 31000 ft,the fuel penalty loss caused by the bleed air accounts for 51.3%of the total fuel penalty loss of the system.An overall optimization of 10%in the air conditioning system's bleed air can reduce the total fuel penalty loss by 5.3%.关键词
