Who the Heck Are You? Systems Engineering

I’m John D. Knapp! I’m an Eastern Montana kid!

Degrees: A.A. (1965) Pre-Engineering, B.S. (1967 in

Mechanical Technology, MBA (1975).

I’ve worked in nuclear reactor operations and nuclear QA (7 years), commercial nuclear QA (6 years) , aerospace and supplier/subcontractor quality engineering (29 years).

My Emphasis is in Procurement Quality Engineering!

Working with people to get a quality product is my goal!

LHot Rodding_3

Who the Heck Are You? Systems Engineering

I’m a Gear Head! I’ve been interested in cars since 1955!

I’m always learning new skills and applications.

Taking welding (Arc and MIG welding) and auto body repair classes @ CCOC in San Jose.

Will be taking machining, automatic transmission repair, tune-up, electrical, suspension, brakes & steering classes.

I don’t plan to retire – I’ll just continue to learn and apply,

until I wear out. Boredom is a slow, painful death.

Systems Engineering

• Systems Engineering (SE): An approach AND a discipline.

• Identifies new methods/opportunities like other engineering fields.

• Note: SE’s approach is holistic (i.e. concerned with complete systems) and interdisciplinary (i.e. works with other applicable disciplines).

• Integrates work-processes and tools to handle projects, (large or small). It overlaps with technical and human-centered disciplines.

• SE helps meld technical contributors into a unified team effort, forming a structured development process that proceeds from concept through production to operation.

• It’s “hot rodding” (integrating subsystems into a “system” or “car”).

Systems Engineering - Definition!

LHot Rodding_5

Premises of This Presentation Are: Systems Engineering

0. Eighty (80) Percent of All Hot Rodding Projects Never Get Done! Why?

1. Work Isn’t Done, Isn’t Planned/Funded!

2. Inadequate Preparation/Education!

3. No Commitment To Learn AND Do! 4. Inadequate Facilities/Tools/Expertise!

Systems Engineering

Hot Rod - a car with an engine modified for linear speed. - typically a roadster or 2-door coupe that was modified for speed.

- a roadster was light; the windshield could be removed.

- burning out connecting rod bearings (hence the term, “hot rod”) was a very common failure in modified four-cylinder Model “T”, “A”, “B” and Model “18 (i.e. V8 Ford; particularly Model “T”s and “A”s with 4-cylinder engines with babbitted main bearings).

The term “hot rod” was adopted in the 1930’s or 1940’s as a car that had been

modified in various ways to achieve higher performance.

A Little Background!

LHot Rodding_7

The Classic Hot Rod!

LHot Rodding_8

Systems Engineering

Original hot rods were old cars that were modified to reduce weight, improve aerodynamics and performance.

Typical modifications were removal of windshields, lowering the chassis, and modifying and tuning the engine for more power/torque or replacing it with a more powerful one for top speed.

“Top chopping” (i.e. removing vertical parts of the car’s roof to lower the aerodynamic profile) occurred.

“Sectioning” (the removal of a vertical “section” of metal from the body) also lowered wind resistance came a little later.

Wheels and tires were changed for improved traction and handling.

Hot rodder’s modifications may or may not have improved the appearance.

Show cars in the 1950s replicated these modifications, added distinctive paint

jobs and all kinds of interior/exterior modifications.

Still More Background!

LHot Rodding_9

Systems Engineering

In 1930’s, the Southern California Timing Association regulated top-speed trials @ dry lakes in California.

The Bonneville Salt Flats became the home of top speed records in 1949.

In the late 1940’s, NASCAR originated from moonshiner cars that used modified engine and suspension. Also, the National Hot Rod Association (NHRA) is born in the 1950’s!

In the 1960’s, the Muscle Car emerged (i.e. the Hemi-Dodge; Ford Thunderbolt; Chevrolet Camaro with an aluminum 427 cu. in. engine).

Maslow’s Hierarchy of Human Needs – Part 2.

You’ve probably guessed this:

1. You’re not building a car, you’re going to have an experience and build YOURSELF + a Car.

2. You have a choice – use your own design, someone else’s or a totally new design!

3. One idea of this build is to challenge your understanding and your point-of-view (i.e. what I see and how I see it) through experience(s) and application(s). This challenge will build, grow, mold & “polish” you. The car is the by-product of this experience!

LHot Rodding_28

What’s Not Mentioned In Maslow’s Hierarchy?

We’ve talked about building a person and a car but we’ve missed a VERY important point!

We haven’t talked about TRANSCENDENCE!

You’re going to transcend your:a. Point-of-view.b. Current knowledge.c. Current understanding.d. Previous experience(s).e. The experience(s) of other’s who’ve

also done this work.f. Our previous self-actualization.

LHot Rodding_29

Then You Get Into the “Real” Stuff!

• The “Real” Stuff is THE KNOWLEDGE that you find out about the hardware, the build and the insight that you get from this experience –

THAT NO ONE ELSE BUT YOU AND A FEW OTHERS (WHO’VE DONE THIS WORK) ACHIEVED!

LHot Rodding_30

Lessons of Previous Automotive Work!

1. The “De Saxe” Principle in Ford Flathead V8 and 1920’s Ford Four-Cylinder Engines!

The crankshaft is offset 0.265” to the left of engine center!

Why?

LHot Rodding_31

The “Side-Oiler” Ford OHV V8 Block!

The main bearings get the oil first, in a side-oiler Ford V8!

Why?

What was the application?

LHot Rodding_32

The SR-71 Engine Experience!

“Lockheed’s gearbox manufacturer had NO experience with metals or materials that would see the temperatures of the flight regime of this aircraft”.

Neither Did We – But, We Were Already Committed To Learn!

Bill Brown–Pratt & Whitney Program Manager for

the J-58 Engine (1981/82 Lockheed Magazine).

LHot Rodding_33

What Did You Know About Threaded Fasteners?

LHot Rodding_34

Get Ready – You’ll Learn What Others Don’t OR Won’t!

1. Why are torque wrenches an ineffective way to preload (i.e. “torque”) threaded fasteners?

2. What’s the most effective installation method for T/F’s?

3. Why is a stud (a bolt with threads @ each end) much more effective @ clamping than a screw?

4. Why was the first thread that was standardized, more effective, in its time than other types of threads that were developed later?

LHot Rodding_35

You’ve Been a GREAT Audience!

• Thank YOU for attending and allowing me to share my “gear head” experience(s)/insights with you.

• Your Attention is VERY MUCH appreciated.

• Please continue to be an eternal student – a continual learner AND share your knowledge with other students (i.e. be a “genuine” (i.e. agape) teacher, with no strings on your sharing your knowledge) .

• If you’d like to provide feedback about this presentation, please call John Knapp @ (408) 743-1802 or send an e-mail to john.knapp@lmco.com.

Last But Not Least………

A Hot Rod Should Be Constantly Improved or Changed. Why?-------------Because Technology Changes/Improves.
