Adjusting the static moment of a rotor blade |
摘要 |
In finishing the construction of a rotary wing, particularly helicopter rotor blade, the blade is weighed to determine the position of its static moment. The measured value is compared with a predetermined value and, if necessary, the static moment is adjusted by applying a high specific gravity filler material to the surface of the blade. The filler material has a specific gravity in a range of 6 to 10 p/cm3 and can be formed of a mixture of tungsten powder and epoxy resin. The weighing operation is performed on a three scale apparatus with one scale supporting the end of the blade attached to the rotor and the other two scales supporting the opposite end of the blade.
