Geometric Dimensioning and Tolerancing

Description

Geometric Dimensioning and Tolerancing

In this project we scanned the left and right hand propeller blades of a 7000 HP towboat.  The problem being addressed was to determine the geometric differences in the wheels that cause differences in their performance. Even though the pitch and diameter are identical between the two sets of propellers, one set performs better than the other.  A point cloud was obtained for each propeller and we analyzed the differences to determine where additional repairs were needed to improve the underperforming set.
