Summary

The Environmental Control System, ECS, represents a constant power demand over the complete flight envelope, regardless of engine project. This thesis focuses on the definition, design, sizing, and simulation of the ECS for hypersonic civil aviation. The ECS is an innovative way to conceive this subsystem, never experienced before. At subsonic and supersonic speed, until Mach 3, open-loop ECS is assumed, in line with traditional commercial aviation systems to meet entry-into-service requirements. From Mach 3 to Mach 4, there is a transitional phase in which open and closed Loop coexist. At hypersonic speed, a full closed-loop system is the optimal solution given present data. The Carbon Dioxide Removal Assembly (CDRA) and Trace Contaminants Control Subassembly (TCCS) are responsible for removing CO2 and contaminants to provide clean air to passengers. The target of the work is to define a proper architecture for the subsystem and verify its compliance to the mission. The necessary air flow to cool down the cabin into +18oC to +25oC temperature range is obtained and compared with the mass flow rate required for breathing. Architecture design is hypothesized and open to future development, including using CO2 from CDRA to create oxygen exploiting Sabatier reaction or exploiting electrolysis to use water condensed in Air Cycle Machine (ACM) to produce oxygen to enrich the air in the cabin.
