More measurement for maximum geometrical accuracy

Whether the potentials of the propeller design can be exploited depends largely on the technological implementation. By using Optical Precision Measurement (OPM) MMG guarantees the highest design accuracy in all dimensions.

The propeller is scanned with an accuracy of up to 1/100 mm – from the cast blank to the final grinding – using fringe pattern projection and an optical sensor. The propeller is only awarded the »Efficiency by MMG« certificate when the results of the OPM are in perfect alignment with the design geometry from the Multidata Design Concept. In this way we guarantee that our propeller will achieve the calculated and predicted performance in full scale on all oceans.
