(R) Environmental Control System Contamination
|Publication Date:||1 May 2020|
This SAE Aerospace Information Report (AIR) includes a discussion of liquid and particulate contaminants which enter the aircraft through the environmental control system (ECS). Gaseous contaminants such as ozone, fuel vapors, sulphates, etc. are also covered in this AIR. This publication is concerned with contamination sources which interface with ECS and fuel tank inerting systems, and the effects of this contamination on equipment. Methods of control will be limited to the equipment and interfacing ducting which normally falls within the responsibility of the ECS designer.
The purpose of this AIR is to categorize sources of ECS contaminants, define the effects of these contaminants on equipment, and outline design features that can be used to control contamination in aircraft systems.
