Abstract

The article presents the main principles, methods and techniques for assessing the tightness of fabric-film materials (FMM) and flexible pipelines of air conditioning systems (ACS) of aircraft made of them. The tightness of these products is one of the main requirements and is necessary for the reliable functioning of the ACS. The article presents a method for calculating the tightness indicators during tests using the manometric method, diagrams of a device for monitoring the tightness of the TPM, a stand for testing the tightness of flexible pipelines, and a brief technological process for performing tightness monitoring operations.
