TEST DEVICE FOR AERONAUTICAL COMPONENT

Test device for an aeronautical component ( 2 ) wherein M low- energy impacts are performed on the component to be subjected to testing ( 2 ) by calculating the relative uncertainty Ui of the non-destructive tests. A destructive test (block 120 ) is performed on the aeronautical component ( 2 ) by measuring and storing the value of a quantity VI representative of the elastic stress applied to the component during the destructive test and based on this the uncertainty of the destructive test is calculated (block 130 ). The absolute value of the difference between target values of quantities Ci based on a theoretical model that describes the elastic behaviour of the component to be subjected to testing and the value of the quantity VI representative of the elastic stress applied to the component during the destructive test (ABS ( Ci -Vi ) ) is compared with the product of the uncertainty of the destructive test Al and a scaling factor k in order to certify the theoretical model as describing with sufficient accuracy the behaviour of the aeronautical component during the destructive test.
