A new type of aircraft environmental control system (ECS) using a membrane-based high-pressure air dehumidification package is proposed. According to its working principle, the mathematical models of key components of the system are established, based on which a performance simulation of this new type of ECS is carried out with module structure models, and this performance is compared with that of a conventional two-wheel high-pressure water-separation ECS. The simulation results show that the simulation model has good dynamic response and steady-state values, and the new aircraft ECS using membrane dehumidification possesses some advantages in terms of system structure, performance and weight compared with the conventional system. Therefore, it is worthy of further system experimental research to lay a good foundation for the development of a new type of membrane-based air dehumidification aircraft environmental control system (MADECS).
