A Flexible Toolkit for the design of environmental control system architectures

Abstract

One of the core systems in a conventional or More Electric Aircraft (MEA) is the environmental control system (ECS). It is either the key consumer of pneumatic power or draws a substantial load from the electric power system. Therefore, it is crucial for the trade-off between aircraft and engine design and an important element of a tool to assess system architectures at aircraft level. Drawing on these findings, this paper presents the development of a dedicated simulation tool to evaluate potential ECS architectures in conceptual design with respect to systems weight and performance metrics such as electrical power demand or engine bleed air mass flow.
