Catch-22 for any New Graduate
 You want to gain experience.
 Employers are looking for experience.
 You need experience to gain experience.
There was only one catch and that was Catch-22 . . . Orr was crazy and could be grounded. All he had to do was ask; and as soon as he did, he would no longer be crazy and would have to fly more missions. Orr would be crazy to fly more missions and sane if he didn't, but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to.
– Joseph Heller, Catch-22

I’ve taken some classes . . .


Coursework = Experience
•
Classes are learned knowledge
•
Jobs are applied knowledge
Disliking a course ≠ Disliking the job
 Internships allow you to:
•
Combine information from different courses
•
Experience a company’s culture
•
Find out what you like or do not like to do

Becoming an Engineer . . . .
 School teaches how to solve small problems
 Work teaches how to define the problem and then divide it into smaller problems


Multiple solutions to every problem
•
Not every solution is feasible
Almost everything is done as a team
 You never stop learning

Solid Rocket Propulsion
 All types of engineers involved
•
Chemical, Mechanical, Materials,
Manufacturing, Systems, Aerospace
 What do engineers work on?
•
Design
•
Propellant formulation
•
Material composition
•
Computer Modeling
•
Testing
•
Transportation
•
Safety
•
Manufacturing
•
Systems Integration
•
Risk Analysis
•
Technical Papers
•
Presentations

Research & Development
 Create an idea/concept
 See if the idea/concept is viable
 Future-Oriented - Long-term activities
 Part of nearly every company or organization
 Potential for high risk of failure
 US spends approx $330 Billion/year

Test & Evaluation
 Further development of idea/concept into a product
 Clearly defined matrix of tests
 Helps define concept maturity
 Failure analysis
 Pre-Production run
 Beta testing

Engineering Courses I Use
 Technical Communications
 Thermodynamics / Heat Transfer
 Combustion
 Structural Design
 Mechanical Properties of Materials
 Computer Aided Design (CAD)
 Statistics
 Physics / Linear Algebra

What I’ve learned about being an Engineer
 Projects are long-term (months to years)
 The solution is rarely known in advance


Engineering is more than technical ability
•
Lots of teamwork, presentations, reports
•
Customers, Suppliers, Contracts
Work isn’t like school
•
You don’t take it home with you!

What I’ve learned about being an Engineer
 Communication skills are important
•
Written and Oral
 You can never know everything
•
Experts just know more than most people
 Find a Mentor
•
