LOW PRESSURE COMPRESSOR BLEED EXIT FOR AN AIRCRAFT PRESSURIZATION SYSTEM

摘要

An aircraft pressurization system, includes an auxiliary compressor for further compressing compressed air received from a low pressure compressor section of a gas turbine engine while the compressed air is below a predetermined pressure level; a bleed passage for fluidically connecting the auxiliary compressor to the low pressure compressor section; and an environmental control system coupled to an output of the auxiliary compressor for conditioning the compressed air to a predetermined level.

主权项

1. An aircraft environmental control system comprising:
a multi-spool turbine engine having at least one low pressure spool and at least one high pressure spool; a bleed port located on a low pressure compressor of the low pressure spool; a bleed air passage configured to deliver high pressure engine air from the bleed port of the low pressure compressor to an environmental control system.
