DEVICE AND METHOD FOR MEASURING AND CALIBRATING THE CONTROL ANGLES AND CONTROL FORCES OF A ROTOR BLADE

摘要

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.
