DEVELOPMENT OF AIR COUPLING SEAL FOR BOEING B-747 AIRCRAFT

A new coupling seal for the air duct of a Boeing B-747 aircraft has been developed as a substitute for the conventional one which has an unsatisfactorily short service life. This report describes the testing results of the new seal as well as several types of conventional seals. The first tests were conducted to determine the best materials for and design of the particular seal. Then sample seals and conventional ones were subjected to various kinds of tests such as leakage tests under heat cycle of room temperature to 230 degree C, and ease in installing the seal into the coupling rig using simulated test jigs.
