Helicopter Rotor Blade Static Balancing Instruments

Product Details

Raptor Scientific is the world’s leading manufacturer of Helicopter Rotor Blade Balancer Systems.  These two-axis Weight and Center of Gravity measurement instruments use the multi-point weighing method.

Each rotor blade is positioned using pins to interface with the root lug holes.  A post located past the center of gravity of the blade would provide support to keep the blade horizontal during measurement.  The blades are loaded in a horizontal position (“flight configuration”) in order to measure moment weight in two axes, along span and chord.

System software directly reads the absolute value of moment weight.  If the length from the root to the weight adjustment location is entered, the software will calculate the amount of additional weight needed to balance the blade.  The system output can be configured to be an absolute moment weight value or a deviation from a master blade.

Blades weighing up to 200 pounds can be accurately measured for weight and moment due to CG offset.  We also offer adjustable fixturing options to accommodate various blade types.
