Akin’s Laws of Spacecraft Design - #3
Design is an iterative process. The necessary number of iterations is one more than the number you have currently done. This is true at any point in time.

A Word on Homework Submissions...• Good methods of handing in homework
– Hard copy in class (best!) – Scanned or electronic copies via e-mail (MUST put
“ENAE483” or “ENAE788D” in subject line) • Methods that don’t work so well (for DLA)
– Leaving it in my mailbox (particularly in EGR) – Leaving it in my office – Spreadsheets or .m files – Handing it to me in random locations – Handing it to Dr. Bowden

Design/Build/Test/Evaluate• Hardware design, fabrication, and testing can be
a valuable part of the 483/484 capstone projects • A requirement for this term is to figure out
exactly what you’re building next term • Choice is based on
– Getting design data unobtainable by analysis (e.g., examine human mobility in low gravity)
– Enabling meaningful mission simulations – Providing value for competitions
• Leverage the facilities and infrastructure of SSL

Experimental Studies in ENAE 483/4• Traditionally, experimental studies are second-
term (484) activities • Would be ideal if experimental results were in
time to affect 484 design efforts (before PDR in early March)
• Generally get results after CDR (late April) • Intent to put significant effort into design and
(potentially) construction of experimental hardware to ensure results are in time to improve 484 design

U N I V E R S I T Y O FMARYLAND
A Word about CAD• Computer-aides design is an important tool for
all engineering, and an essential tool for a designer
• The best way to learn CAD is to use it - a lot! • In a project team of this size you can’t have
everyone use whatever system they feel like - since Siemens made a major gift of software to UMd, we are all going to use NX this year
• “Resistance is futile”

U N I V E R S I T Y O FMARYLAND
Some Thoughts on Teamwork• Your entire career will be spent doing
engineering in teams • You have had team experiences before (e.g.,
ENAE 100, ENES 100) • This is intended to be as close as possible to your
professional experience, except for a flat organizational structure (i.e., you can’t fire anyone)
• Nothing can guarantee the success of a team - but a lot of things will guarantee its failure

U N I V E R S I T Y O FMARYLAND
Some Thoughts on Professionalism• In this class, like life, you won’t like everyone
you interact with • Nevertheless, you owe everybody respect and
support where necessary • Hopefully it’s not necessary to say it, but there
will be zero tolerance for discrimination on the basis of gender/race/nationality/sexual orientation/etc.
• You also owe your team(s) your best effort and dedication to the project(s)

U N I V E R S I T Y O FMARYLAND
Closing Comments• Focus on numerical analysis and systems
engineering → this is not “hardware-bashing” • Look for your own design solutions → this is
also not “catalog shopping” • Approach everything rigorously with numbers →
this is also also not “adjective engineering” • Manage scope and risk along with cost, mass,
and other design parameters • Be innovative, while remaining real • What you get out of the process is directly
proportional to what you put in

Today’s Assignments• Go to https://ter.ps/483F19L1 and take the short survey
about the class and today’s lecture • Go to the RASC-AL web site (http://rascal.nianet.org)
and get familiar with the material there, particularly the descriptions of the themes and the information on their assessment criteria
• Watch the posted video clip on the design of the Apollo Lunar Module from the episode “Spider” of the HBO mini-series “From the Earth to the Moon”
• Do the rest of the assignment linked at the bottom of the Lecture #01 splash page.

Not having all the information you need is never a satisfactory excuse for not starting the analysis.
