METHOD OF DETERMINATION OF BODY STATIC MOMENT Russian patent published in 2008 - IPC G01M1/12 G01L3/00 

FIELD: metrology.

SUBSTANCE: invention relates to metrology, in particular to methods of determining the body static moment, primarily, that of elongated bodies, and can be used for measurement of the turbine machine blade static moment. The method includes the determination of reaction in the system measuring support, revealing the reference point, fastening the elongated body on the beam and calculation of the body static moment. First, the reaction in the measuring support is measured without fastening the body thereto, and this position is taken to a reference point. Then the body is fastened on the beam between the measuring and fixing supports to allow a two-position fixed location relative to the fixing support. The reaction in the measuring support with the body in the first position is measured. Now the body is moved to the second position to measure the reaction in the measuring support for this position of the body. The body weight "Р_л", the centre of gravity grid point a, and static moment M_s relative to the body base surface are calculated. The static moment M_cr of the body relative to any base axis is determined.

EFFECT: wider potentialities of the method.
