- 1985,
Special Recognition Award for Test Stand upgrades including design and implementation
of custom programmable liquid flow metering system.
- 1995,
Division ROI Award (team member) for bringing in-house PW2000/4000 Engine Component
rework and calibrations. My contribution was the design & construction of
the Electronic Test Consoles and some of the procedures.
- 1995,
Certificate Of Achievement: Dorries High Speed Grinder Quality Improvement Team.
Original
Designs:
- 1973 - 1976, Pulsed Arc Welding Apparatus (see attached patent)
Patented apparatus (PN=3,989,922) that was a forerunner
to the pulsed welding feature on modern TIG & Plasma welding processes.
This attachment to existing TIG & Plasma welders enabled repairs of certain
engine cases and other titanium parts resulting in a minimum savings, for UAL,
of $160,000 in the first year it was used. It was used more or less continuously
for 10 years until it was displaced by more modern OEM equipment.
- 1978-1980, Liquid Flow and Miscellaneous Parameter Calibration System
for Engine Component Test Stands
This incorporated a Commodore PET computer and some OEM
Instruments to enable calibrations of the test stand gauges while still
installed in the Test Stands.
- 1978-1983, Electronic Accuracy Compensation
Circuitry for NC Machine Tools
This predated the compensation feature now provided by
nearly all control vendors. Installing the electronic compensation circuitry
in the control of an “out of spec” rotary table yielded performance exceeding
OEM specs. This permitted deferral of purchase of a new rotary table for about
9 years. The value of this 6-week design effort was, by the machine shop’s estimate,
greater than $150,000.
Accuracy of linear axes on other NC equipment was also
improved. On a Burgmaster Bridge Mill, with this feature installed, accuracy
was improved enough so that special fixtures could be reliably manufactured
on the machine. This produced more $$ and time savings.
- 1985-1987, Programmable Liquid Flow Metering System for Jet Engine
Test Stands.
With my design and implementation of this system, UAL
was able to bring engine nozzle testing in-house (previously outsourced to Garret
Air Research) resulting in $$ & time savings. I received a Special Recognition
Award for this.
- 1995-2002, Programmable Multi-Purpose Jet
Engine Component Test Console
This multipurpose tool for testing/certifying engine components
such as SVAs (Stator Vane Actuators), AOHEVs (Air Oil Heat Exchanger Valves),
and many other engine component types was part of the 1995 Division ROI award.
It is configurable so that new parts can be easily added
to its database of qualified items. Cost to manufacture is approximately $50,000
(as opposed to cost to purchase an OEM unit for more than $150,000). In addition
to the Component Test Console’s greater versatility, certain evaluations suggest
that it is more accurate than the OEM units, i.e. it meets or exceeds
the OEM requirements.
- Other accomplishments on request.
Equipment/Design
Modifications:
- 1969-1971, Balancing Machine Electronics Redesign
To achieve the redesign necessary to address machine reliability
issues, I “transistorized” the vacuum tube technology within the original Gisholt
equipment. I designed and manufactured printed circuit boards to accomplish
this.
The result was essentially zero downtime and improved
process accuracy during the 1970s. This was a modest $$ savings in terms of
reduced maintenance costs, but the real benefit was in cycle time reductions
(due to the reduced down time) when balancing engine parts.
- 1980-1982, AMS (Asset Management System) Mark V Computer Modifications
When Alton Technology (a contractor)
went bankrupt during installation of UAL’s first generation Asset Management
System (which includes keycard entry to the MOC), SFOMP Ron Brooks (another
maintenance specialist) and SFOMP Jim Trainor (the Plant Maintenance Manager)
requested that I evaluate the issues and assist in saving the project. This
was a $1,600,000 project and had zero reliability and zero component interchangability
(as left by the contractor).
I re-manufactured three PDP11/03-based DEC Computers and
made many other system improvements of an electrical/electronic nature. Within
a year our efforts literally saved the project.
- 1995-1996, High Speed Grinder Enhancements (Electrical, Mechanical,
and Software)
When the machine shop was contemplating buying a new high
speed grinder, I was asked for my opinion. I decided that improvements to the
Dorries were possible, would be less expensive, and could deliver needed functionality
sooner.
I suggested and directed certain mechanical improvements
and created software that took advantage of those mechanical improvements. This
resulted in the Dorries Grinder performing much better (+/- 0.0005”) than its
original specifications. The improved accuracy was sufficient to meet the P&W
spec for the PW40xx rotors (+/- 0.001”).
As a consequence, no OSV grinds of PW40xx rotors since
1995 have been required. This accounts for more than 300 PW40xx rotors ground
in-house as well as quality improvements for all other rotor types. At an estimated
OSV charge (including shipping) of $20,000/rotor, these changes have yielded
savings (not counting cycle times), since 1995, exceeding $8M (this includes
a one time first year savings of about $2M, estimate by SFOEP). Cycle times
have been reduced from a minimum of 3 weeks to 1 day.
