The device and method for measuring the chordwise gravity center parameters and the height gravity center parameters are provided and used for measuring the gravity center parameters of the helicopter rotor blades.

Description

Technical field [0001] The invention relates to the field of measuring the parameters of the center of gravity of a helicopter rotor blade, and further relates to a device and method for measuring the parameters of the center of gravity of a helicopter rotor blade. Background technique [0002] The static characteristics of the blades on a helicopter are determined by the structural parameters of the blades, and their joint action determines the characteristics of the blades. Therefore, in the calibration process of the blade, the static structural parameters of the blade are the first step to be carried out. First of all, it is necessary to ensure that the static parameters of the blade are consistent and stable. The calibration of the blade must ensure the consistency of the static parameters and the dynamic characteristics. The comprehensive effect of the static parameters is shown by the dynamic characteristics. They collectively affect the dynamic characteristics of the blad...
