[0027] Example: see figure 1 , figure 2 .
[0028] figure 1 It shows the load condition of the aircraft after it is overturned. In the figure, G is the center of gravity of the aircraft, and P w - downward inertial load; P f -Friction force at the ground point of the cockpit; the horizontal reference line of the aircraft in the figure is used to mark the horizontal plane of the aircraft. During the test, the horizontal reference line should be used as a reference to calibrate other positions, such as the position of the stress measurement point and the position of the displacement measurement point. The direction indicated by the arrow in the figure is the taxiing direction after the aircraft is overturned.
[0029] figure 2 Shown in the aircraft overturning test device of the present invention, and the aircraft overturning test method on the basis of this device.
[0030] An aircraft overturning test device comprises a test platform 2 and a support 8 for supporting th...
