  • Method and apparatus for checking the bonding of a cellular structure to a support
    Patent number: 5078005
    Abstract: The bonding of a honeycomb structure to a support at one end of the cells of the structure is checked by applying a detector to the opposite end of the cells, the detector comprising first and second compartments which are separated by a partition, supplying compressed air to the first compartment, and measuring the flow of air out of the second compartment by means of a flowmeter connected to an outlet from the second compartment. The flow value measured by the flowmeter enables one to determine whether or not there are any non-bonded areas between the honeycomb structure and the support in the region of the detector.
