Abstract
The invention discloses a helicopter rotor blade static balancing fixture. First, the blade is rooted to provide a basis for accurate station or spanwise measurements. Then, weight information is measured by the load cells, and the distance from the weight measurement to the leading edge of the blade is measured by linear transducers, respectively, and communicated to a computer. The computer calculates the spanwise moment, compares the calculated value to the factory standard spanwise moment, and calculates and displays a recommended weight adjustment. The computer calculates the chordwise moment, compares the calculated value to the factory standard chordwise moment, and calculates and displays a recommended weight adjustment.
