    • This invention concerns a stress test rig consisting of a rigidly mounted part, which contains the devices uniformely used for all types of test gears, and an assembly truck (37), which holds the test gear (16) and the required adapter devices. A test rig gear unit (2) forms a continuous stress circuit with a superimposed gear unit (9), an adaptation gear (23), and a second test rig gear (19). The stress moment is set by a control unit (15) through the superimposed gear unit (9). The regulation variable for the stress moment is determined up to more than 80 % by a neuronal network (31). The test rig gear unit (2) is a conical gear wheel and the superimposed gear unit (9) has a conical gear step (13), so that the output shaft (14) of the superimposed gear unit (9) is pivoted and has a height adapted to an input shaft of an adaptation gear unit (23) or of a test gear unit (16).

    • The device is mounted in the position of a rotor blade on the rotor head (38) of a testing bench or helicopter. Said device has the same geometry as the connecting points to the rotor head and to the control rods (44), similar to a rotor blade. Said device enables the same relative movements of the connecting points, similar to rotor blade. As opposed the use of a rotor blade, a defined support surface (32) for a position measuring equipment on the device makes it possible to measure in a better reproducible way and faster the control angles predetermined by a control system. The possibility of fixing standard weights (36) on a lever arm (28) of the device allows for the impression of a defined longitudinal force to the control rods (44) when the rotor blade is not operational so as to be able to calibrate an integrated force measuring system (46). Said device may also be used when the rotor is working.
    • 该装置安装在在试验台上或直升机的旋翼头部(38)的转子叶片的位置。 它具有连接点到转子头和控制棒(44),其为转子叶片的相同的几何形状。 它允许连接点的相同的相对运动,如一个转子叶片。 A所定义的支撑表面(32),用于位置测量装置,该装置允许在使用的转子叶片,转向角,这是由控制系统确定的一个更可再现的和更快的测量的。 用于在装置的一个杠杆臂(28)的校准砝码(36)的附接使控制杆(44)在所述转子为一体的综合功率测量系统(46)极性的校准确定的纵向力的静止状态。 该装置也可与所述转子的运行使用。
