The Prop Eye
The Prop Eye is designed to automatically measure the pitch, rake, tracking and squareness of a marine propeller. Laser technology is used to scan the Z axis. The degrees of rotation along with the radii of the propeller are established through computer interaction with encoders integrated into servo motor drives. The Prop Eye is designed to be fixed on a single tapered center point. The single center point allows the laser to be rotated around the propeller for data acquisition. The Prop Eye scans in both clockwise and counter clockwise directions and records data for up to seven previously defined radii as set by the user. The complete scan can be accomplished in as little as two minutes. The simplicity of a single point fixture also allows for mounting to several different platforms eliminating costly set up time. The Prop Eye can scan a larger diameter propeller while still being able to measure the 50% radius on a smaller diameter propeller.
