摘要： A method of simulating life of a rotor blade mounting feature mounted in a complementary rotor disc mounting feature comprises the steps of providing two specimen mounting features (37) each having portions defining pressure faces matching in profile respective faces of the rotor blade mounting feature; providing a fixture (38) having two opposed mounting features (39) each having portions defining pressure faces (78) matching in profile respective faces of the rotor disc mounting feature; mounting the specimen mounting features (37) in the fixture mounting features (39); applying a first load to the specimen mounting features (37); measuring a strain in a region (86) of the fixture (38) between the fixture mounting features (39); applying a second load to the fixture (38), the second load being substantially perpendicular to the first load; and controlling the second load in response to the measured strain. A high cycle load may simultaneously be applied to the specimen mounting features (37). Claims are also included for an apparatus (10) for carrying out the method.

摘要： A fatigue test system includes a frame having top, intermediate and bottom supports each operatively interconnected by at least one extension, and the intermediate support being disposed between the top and bottom supports. The fatigue test system further includes a driving mechanism connectable to one of the supports to drive the support substantially along a longitudinal axis of the extension for fatigue testing at least one spring disposed between the top and intermediate supports, and at least one further spring disposed between the intermediate and bottom supports. In an alternative embodiment, the fatigue test system includes a frame including top and bottom supports each interconnected by an extension, and a driving mechanism disposed between the top and bottom supports for driving springs against the top and bottom supports, each spring being fatigue tested by being driven along a longitudinal axis of the extension or a central axis of the spring.

摘要： A test apparatus (12) and a method of testing a sample (30) are disclosed. The method comprises receiving a test sample (30) within a test chamber (14), the test chamber (14) containing two or more iron saturation elements (2) separated by a spacer (16); and filling the test chamber (14) with a test solution, the iron saturation elements (2) being arranged to saturate the test solution with iron. Each iron saturation element (2) is shaped such that it has a predetermined surface area such that the ratio of the volume of the test solution to the surface area of the iron saturation elements (2) and the test sample (30) exposed to the test solution can be calculated.
