FIELD: test equipment.
SUBSTANCE: invention relates to test equipment, in particular to benches for aircraft strength tests. The method consists in that for reproduction of pre-set program the sign-variable compression-extention load is applied to one of surfaces of the tested structure, for example, to the wing console - from below. Before tests along the compression channel the pre-set load and movement are established by means of an additional lever and a mobile support. In the offered technical solution the device for testing of aircraft for durability for the method implementation described above is also described. In this device the force excitators through the lever system are attached to the tested structure from one side, and the lever system is fitted with the additional lever with the mobile support allowing to change lever arms.
EFFECT: technical result consists in process simplification and reduction of test time.
