Evaluation of Aircraft Environmental Control System Order Degree and Component Centrality

Air cycle systems (ACSs) are primarily used in aircraft environmental control (ECSs) to provide a suitable cabin temperature and pressure environment for passengers avionics. It comprises heat exchangers, compressors, turbines, water separators, various other components that interconnected form an information-transmission network. Traditional research on ACSs has focused their thermal performance. This study abstracted into network graphs based characteristics, determined the weight of each route using fuel penalty method, calculated compared order degree different structure entropy measured importance component centrality first time. The results showed gradually increased with increase number wheels air machine (ACM), high-pressure separation had higher under wet conditions than dry conditions. Moreover, vertex graphs, ACM secondary exchanger ACS were fundamentally important should be during system design. methodology proposed this provides theoretical basis evaluation organizational design performance components.
