摘要：
The present invention provides a test specimen configured for mechanical load life characterization testing of a dual wall bonded airfoil for use in a turbomachinery device. The dual wall bonded airfoil has a spar and a skin bonded to the spar. The test specimen includes a main stress body, which includes a test spar component configured to represent the spar of the dual wall bonded airfoil; a test skin component configured to represent the skin of the dual wall bonded airfoil; and a test bond joint bonding the skin component to the spar component. The test bond joint is configured to represent the actual bond joint between the spar and the skin of the dual wall bonded airfoil. The test specimen is structured to simulate the dual wall bonded airfoil for testing in a mechanical testing machine.
