초록

This paper is about improvements to prevent the crack on welding parts of bleed air duct and vent tube in Advanced Trainer ECS owing to vibration. The configurations and the path of vent tube should be changed to prevent the crack. To assure the result of improvements, measured the status of each pressure condition attaching pressure censers on duct and vent tube. The result of life analysis shows that a crack does not happen on improved configuration while a crack initiates after 19th flight and thru cracking could happen after the 30th flight on previous configuration.
