1990's to test small-and large-scale rotor systems as described in Refs. 1-3. Based upon the RTA experience (Ref. 1), the LRTA included the design of a calibration stand, which enabled an LRTA-installed rotor balance calibration. Deflection measurements using a laser tracker were acquired during the LRTA balance calibration.
Temperature Compensation for Portable Metrology Hexagon
1. Reference scale bars made of the same material as the part to be measured (this technique is a hold-over from theodolite measurement systems). 2. Another similar technique is to measure two points on the tool and tell the measurement system the “known” distance between those two points. This is a variation of the scale bar method. 3.
