Abstract

Environmental Control Systems (ECS) on civil transport aircraft constitute large portions of the secondary power demand. In this paper, an alternative compression system to the conventional two-port bleed design is presented, which can substantially lower the level of secondary power required for meeting the ECS demand. The concept presented is a novel engine-mounted cabin compression system (EMC2S). The potential benefits of the novel EMC2S over conventional systems are quantified and a multi-disciplinary approach, involving combined engine and aircraft performance analysis, is used to quantify the mission fuel burn of both conventional and novel EMC2S configurations for a reference mission. It is shown that, compared with a conventional system, an EMC2S can achieve up to a 0.72% reduction in fuel burn for a single-aisle short-to-medium-range aircraft with a year 2000 entry-into-service turbofan. Larger savings are expected for higher bypass ratio engines.
