Development of Advanced ECS

For the purpose of saving fuel, improving safety, and comfort, Advanced ECS is developing now. MDC, OBNOGS, Desiccant units, and CO₂ Removers are involved in the Advanced ECS and are developing. System analysis of the Advanced ECS is performed to build up Non-Bleed aircraft. In this paper, we show the development of the components (i.e. MDC, OBNOGS, and Desiccant unit) and the results of system analysis as a non-bleed aircraft and system evaluation based on the regulations.
