Abstract: Devices are provided to measure the mass inertia of moving surfaces (e.g., aircraft components). In certain embodiments, the devices will include a support frame formed by first and second structural frame members which form a space for positioning of a moving surface to be measured for mass inertia. A pivot joint assembly is supported by an upper portion of the first structural frame member while a distance alignment device is arranged at a lower portion of the support frame. The second structural frame member including an extension and a dynamometer supported operatively by the extension. The first structural frame member includes a comparator clock at a lower portion thereof.

Abstract: A method for measuring mass inertia of moving surfaces, comprising the steps of: (a) Alignment of the center of gravity of an assembly (90) formed by the moving surface (50) and a support device (70) fastened to at least two joints (31, 32) in a rest position, this alignment comprising a reading in a comparing clock (40) and driving of an adjusting element arranged in the support device (70) for obtainment of a predetermined value in the comparing clock (40); (b) Measurement of the static moment of assembly (Mstatic) in an intermediate position through a dynamometer (60); (c) Measurement of the oscillation period of assembly (T) in a pendulum position through an accelerometer arranged in the support device (70) and (d) Reading of the static moment of assembly (Mstatic) and that of oscillation period of assembly (T) and obtainment of the inertial moment of the moving surface (Ihhsup)—An equipment (10) for measurement of mass inertia of moving surfaces, is further described, comprising: a structure (20) formed
