Hale Propeller M.R.I. Features
Operates on Microsoft Windows Platform

|| Computer operates just like
the one you are now using|
Because we use the Hale M.R.I. every day in our propeller shop we are continually
developing new features that are added to the software. Additionally, input from our
customers has also resulted in new functions that are included with our software upgrade
releases. Among the assets of modern computer programming language is the ability to make
programming changes readily.
Hale M.R.I. software has multiple data analysis Tools each designed toward one
Propeller Repair. The
first several data tools are designed for and presented to the propeller technician. A
detailed layout of each blade in multiple radii with several hundred interrogations per
radius as well as the computed mean for each radius provide the technician with a detailed
image of each blade. Point to Point Position, Blade Segment Analysis and Section Plot
Graphs for the entire wheel are available in both numeric and graphic formats. This detail
provides the repair technician with an accurate picture of not only how much each blade is
out of specification but also WHERE. As the repair process proceeds the Hale M.R.I. may be used to
document and analyze the progress.
The Hale MRI will even compare one propeller to
another in graphic and numerical formats. The technician can compare port to starboard, a
replacement wheel to an existing wheel or any wheel to any other wheel.The Hale MRI also
has the ability to compare the propeller to factory design files.
At the completion of the repair a report is printed that can be presented to the
customer. The data is presented in a concise manner that is designed to be
understood by the boat owner. (Sample Reports)
The "Import" / "Export" tool allows all of the data to be transferred
from any Hale MRI to any other Hale MRI. A distinct advantage to the
cruising boat owner. Their analysis may be transferred via e mail, direct data transfer or
on disk, insuring that their wheels are repaired to the same configuration even when away
from home port.
Rapid and Efficient
Because the Hale Propeller MRI Software has
been designed by propulsion professionals for propulsion professionals and operates in a
Windows environment, the operation of the system is easy to learn. After only a few hours
of experience most operators are able to complete a full propeller analysis in less than 5
minutes. A full analysis consists of several thousand measurements taken at 35%,
40%, 50%, 60%, 70%, 80%, 90% and 95% radii on each blade.
In order to provide maximum stability and to insure that all critical measurements are
derived from a constant reference the Hale Propeller MRI is built upon a 1½"
thick solid steel table bed supported by 2" welded steel legs. The radial spar
assembly is fixed between two precision ground masts to eliminate unnecessary deflection.
Due to the strength and rigidity of the platform assembly and its center of gravity,
propellers up to 50 inches in diameter and up to 500 pounds may be safely and conveniently
The rotating portion of the table assembly uses bearings of such capacity and tolerance
that any propeller is easily rotated by the operator with almost no effort.
High Resolution Astronomy Grade Optical encoders
transmit extremely precise three dimensional position data to the computer. The information supplied by these
devices allows the software to determine and calculate not simply pitch but also camber,
rake, track at any point on any blade and blade geometry. These encoders are identical to
those used in astronomical telescopes to accurately locate and center a single star.
Calculation = 0.0000000000001 in.|
||Data Display = 0.001 in.|
||The Hale MRI is calibrated to Certified Standards traceable to the |
National Institute of
Standards and Technology of the United States
The entire electronic interface to the computer is
accomplished through a specially designed dedicated single printed circuit board (PCB).
This PCB is integrated into the computer via one of the computer's expansion slots. Not
only does the PCB provide all of the data interface to the MRI but also supplies power to
the system. No additional power supplies or cables are required.
Following data collection all mathematical and analysis functions are performed within the
proprietary Hale MRI software with simple "point and click" commands.
